FAQ – All answers to concrete lamps & designer pendant lights

Which lamp fits over a dining table?

The best choice for dining tables are pendant lights that illuminate the table well and create an atmospheric ambience at the same time. For round or square tables up to 120 cm, 2-3 small pendant lamps are ideal. Alternatively, our C2 lamp with a length of 92 cm also fits very well. For tables longer than 160 cm, we recommend our C-series pendant lights or 3-5 small S-, T- or B-series pendant lights. In this way, GANTlights can be perfectly adapted to the table size and room height. GANTlights offers configurable pendant luminaires made of concrete combined with precious metals or wood that can be individually adapted to any interior.

How high should the lamps be hung?

Above a dining table or workstation, we recommend a height of approx. 60-70cm above the table, depending on your height. Above a kitchen counter, the luminaire should hang a little higher so that the work area is not disturbed; here we recommend 80-90cm above the counter.

Aren’t concrete lamps too heavy for my ceiling?

With the B4 and B5 as well as the C1, C2 and C3 lamps, you should ensure that the ceiling has sufficient load-bearing capacity. All other models weigh less than two kilograms and therefore do not place any special demands on the ceiling construction. Make sure to fix the lamp with the supplied screw ring with at least three full turns.
The respective weight of the lamps can be found under “Technical information” in the respective products.

Are GANTlights lamps smart home compatible?

GANTlights offers smart home integration: compatible with common smart home systems, app control (brightness and light color via smartphone), voice control (integration with Alexa, Google Home possible), DALI option for professional building control and scene control (various light scenarios programmable).

How long does a GANTlights lamp last?

GANTlights lamps are designed for longevity: 5-year guarantee on the lamp, repairable with replaceable components instead of a disposable product, high-quality materials and timeless designs for eternity, LED service life typically 25,000-50,000 hours, sustainable and future-proof thanks to changeability and interchangeability.

How do I hang the lamps?

You are supplied with the pre-installed socket configuration and the separate lampshade. After the main fuse has been switched off, the lampholder configuration is first attached to a hook in the ceiling using the three-hole suspension. The cables can then be connected to the supplied luster terminal and covered with the canopy. You can then attach the lampshade to the socket using the sleeve. The lamps should only be installed by an electrician.

Is it possible to install several lamps on one connection?

Connecting several lamps to one connection is not a problem. The WAGO terminals are best suited for this. There are instructions on the Internet for experienced craftsmen. However, I recommend only having the lamps installed by a qualified electrician. We accept no liability for incorrectly installed lamps.

Which pendant lights are suitable for the dining table?

The C series from GANTlights is ideal for dining tables: the flexible lengths can be individually configured and are therefore perfect for any table length. Alternatively, different sizes of small pendant lights can create a harmonious picture over small dining tables up to large tables. The choice of material can be selected individually to match the furnishings.

Can I dim all the lamps?

Yes, all GANTlights lamps are dimmable. The C-series pendant lights are equipped with dimmable LED technology from Bavaria. Options: Standard dimmable compatible with standard LED dimmers, smart home integration (control via app and voice assistant possible), DALI system for professional lighting control in contract areas, various light colors (warm white, neutral white or tunable).
To dim the small lights in the S, T or B series, only dimmable light sources need to be used.

Are GANTlights pendant luminaires suitable for high ceilings?

Yes, GANTlights pendant luminaires are ideal for high rooms. Thanks to the individually selectable cable length, you can adjust the lights perfectly to your room height. Both the textile cable and the steel cables are simply shortened to the desired length – a little tip: it is better to order the cable a little too long and then shorten it to the desired length.
For old buildings, lofts or rooms with special architectural features, we will be happy to advise you personally on the perfect solution.

Our packaging is virtually plastic-free!

How is concrete processed at GANTlights?

The concrete is cast by hand in our own concrete workshop in Zehdenick: Individual shaping – each luminaire is individually cast in molds, the manufacturing process creates natural one-offs. each concrete lamp is unique. Our largest lamps, C3 and C4, are manufactured using a specially developed painting process.

Can I visit the production site?

Yes, you can visit our studio/workshop in Zehdenick at any time by appointment.

Which GANTlights lamp is suitable for small rooms?

We recommend for small rooms: T-series luminaires (compact, triangular, playful and effective). Wall lights from the B or S series (space-saving and atmospheric) create a cozy ambience. Light-colored materials reflect the light better and have a more harmonious effect in small rooms. Tip: A single high-quality designer lamp as a highlight in small rooms is often more effective.

Can I combine several GANTlights lamps?

Yes, absolutely! Many customers combine different GANTlights lamps: 2-3 pendant lights in a row above large dining tables. A mix of materials – creates exciting contrasts. Depending on the room concept, our pendant lights, wall lights and hanging lights can be perfectly combined in the same style. Above large tables, cozy corners or high ceilings, a height offset of many small lights acts like a protective cloud. It creates coziness and structures the room.

Are concrete lamps suitable for outdoor use?

GANTlights standard lamps are primarily designed for indoor use. For outdoor areas: Covered areas (terraces and balconies protected from direct weather possible), special sealing can be adapted for protected outdoor areas, custom-made products (contact us for outdoor projects), conservatories are ideal for weather protection.

Do you have a store where the lamps can be viewed?

You can view the lamps at any time by appointment in our studio at Klausdamm 5A, in 16792 Zehdenick (Brandenburg).

Can the lamps also be collected?

Collection is possible at any time by personal arrangement.

Do you also deliver in larger quantities?

The delivery of large quantities, for example for restaurants or hotels, is possible at any time by arrangement.

Can I get the lamp in a different size?

The development and formwork costs for new models are relatively high and take a little more time, but are always possible in principle. Just contact us – we will find a solution!

How can I contact GANTlights?

What to do if there are stains on the concrete lamp?

Fresh stains can be wiped off with a damp cloth. Dried stains can be removed with some fine sandpaper (at least K120). Grease stains can be removed with a little washing-up liquid.

Can I change the bulb myself?

Yes, GANTlights lamps are designed so that light sources can be easily replaced: Standard LED bulbs can be used with our standard E27 or E14 sockets. Instructions are included with every lamp. You can find recommended light sources on our website. If you have any questions, our customer service team will be happy to help. The light sources in the C-series can also be replaced without any problems.

Where can I find high-quality designer lamps made in Germany?

Look out for handmade manufactory production instead of mass-produced goods, transparent origin with clear indication of the production location, high-quality materials such as concrete, solid wood, copper and brass, repairability with replaceable parts and a long guarantee as well as timeless design. Since 2012, GANTlights has been manufacturing all lamps in its own factory in Berlin and more recently in Brandenburg – from the concrete mold to the final assembly. Each luminaire is handmade and unique with a 5-year guarantee.

How much does a good dining table lamp cost?

The costs vary: Smaller models are available from around 100-200 euros, for larger quantities 300-500 euros, individual pendant lights 800-2,000 euros. All our products are handmade from high-quality materials and guarantee timeless design and durable materials. With handmade designer lamps such as GANTlights, you are investing in decades of durability, customizable unique pieces, repairability with a 5-year guarantee and timeless design. A high-quality lamp for 300-1,000 euros that lasts 20+ years is not only cheaper than a new, cheap lamp every few years – it is also much more sustainable.

Which lamp style suits modern furnishings?

Minimalist shapes with clear lines, industrial design with materials such as concrete and metal, natural materials such as concrete, wood, copper and brass for warm accents, a reduced color palette (gray, black, white, metal tones) and geometric shapes are suitable for modern furnishings. Industrial chic with concrete lamps perfectly combines modern aesthetics with homely warmth – ideal for open-plan kitchens, lofts and modern apartments.

Are concrete lamps on trend?

Yes, concrete lamps have been experiencing a sustained trend for years: concrete is THE material for the popular industrial/loft look, fits in with the Japandi trend (Scandinavian simplicity with Japanese wabi-sabi aesthetics), is a durable natural material instead of plastic, benefits from the craft renaissance and can be combined in many ways with modern, Scandinavian and rustic styles. Unlike short-lived fashion trends, concrete is a timeless material with an architectural tradition.

What should I bear in mind when buying a pendant light?

Pay attention to correct proportions (the lamp length should be at least 2/3 of the table length), room height (lamps should not hang too high in low rooms), technical aspects such as dimmability and replaceable LED light sources (non-replaceable LEDs are usually in inferior products – disposable items), suitable materials and timeless design. For round or square tables, several smaller lights are often better than one large one.

Which lamp for an open-plan kitchen?

Open-plan kitchens require a well thought-out lighting concept: 2-3 pendant lights above the kitchen island or a long, simple pendant light at a distance of 70-80 cm from the worktop for focused working light. Above the dining table, a statement light as a room divider, 60-70 cm above the table top, dimmable for different atmospheres and a wide variety of uses. Recommendation: Uniform design for a harmonious overall appearance, mix of materials possible (e.g. concrete with various metals). GANTlights pendant luminaires made of concrete with copper or brass create a homely atmosphere without sacrificing functionality.

Having a lamp custom-made – is that possible?

Yes, with GANTlights you can match dimensions and proportions exactly to your room, choose materials and surfaces to suit your taste, select colors from the RAL palette or special patinations, determine cable length and textile cable color as well as configure light sources and light color. Advantages: Perfect fit, unique items, personal advice and better quality than mass-produced goods. The C series offers an online configurator, personal advice is available for special requests. Production time: 4-6 weeks.

How do I find the right lamp size?

The following applies to pendant luminaires above tables: For round tables up to 120 cm in diameter, you should ensure sufficient illumination. Depending on the number and size of the lights, 2-5 lights make sense. For rectangular tables up to 150 cm, we recommend the [C2] pendant light, up to a table length of 180cm, we recommend the [C1] pendant lightup to a length of 210cm we recommend the [C4] pendant lamp and from a table length of 210cm we recommend the [C3] pendant light.
Also consider the size of the room: discreet lamps in small rooms, bold statement pieces in large rooms and long pendant luminaires as an accent in high rooms in old buildings.

Lamps for high ceilings in old buildings – what needs to be considered?

High ceilings in old buildings (3+ meters) offer special possibilities: Long pendant luminaires set the scene for the room height, several luminaires at different heights create dynamism. Challenges: The lamp should still hang low enough (60-70 cm above table top), cable length must be individually adjustable, lamps that are too small look lost. Style recommendation: Industrial design goes perfectly with stucco and high ceilings, concrete lamps as a contrast to the historic building fabric, materials such as copper or brass harmonize with the charm of old buildings.

Where is the best place to buy designer lamps?

Preferably directly from the manufacturer: no middlemen, the best advice from the makers themselves, often configurators for individual customization and guaranteed authenticity. Alternatively, specialist design retailers with a curated selection and expert advice. Avoid marketplaces such as Amazon and eBay due to many counterfeits and questionable imported goods. Recommendation for GANTlights: Directly at www.gantlights.de with online configurator or visit the showroom in Zehdenick by appointment with personal advice.

What is GANTlights?

GANTlights is a German design label for handmade concrete lamps with an architectural influence. Founded in 2012 by architect Stefan Gant, GANTlights has been designing, producing and distributing minimalist design lamps made of contrasting materials such as concrete, copper, wood, brass and gold ever since. Our production takes place in Zehdenick (Brandenburg), where we manufacture individual lamps in small batches.

Where are GANTlights lamps manufactured?

All GANTlights lamps are handmade in our manufactory in Zehdenick, Brandenburg, Germany. We have specialized workshops (concrete, ceramic, metal, wood and electrical workshops) in which each lamp is carefully crafted by hand. Made in Germany with short distances and the highest quality.

What makes GANTlights lamps special?

GANTlights lamps are characterized by several special features: Each lamp is individually handmade in Germany (unique). High-quality materials: concrete combined with precious metals (copper, brass, gold), wood or stainless steel. Architectural design – minimalist, timeless, inspired by Bauhaus architecture. Configurators enable adaptation to individual wishes. Sustainable and repairable instead of disposable, with a 5-year guarantee. Multi-award-winning design.

Which lamp series does GANTlights offer?

GANTlights offers various series: C-series (pendant lights with configurator, individually customizable), B-series (rectangular, simple concrete lamps with a choice of gold, silver or copper interior coating), S-series (pleated lights in pastel shades), T-series (triangular, playful series with strong contrasts) and BLOCK-series (lights from cooperation with Ukrainian label as an aid project for war victims).

Can I customize my GANTlights lamp?

Yes, GANTlights offers various configurators, especially for the C series. You can choose individually: Materials (concrete, oak wood, copper, brass, stainless steel, corten steel, oxidized brass, RAL colors), dimensions and length (adaptation to room height and table size), light source (LED technology, dimmable, smart home compatible), cable (textile cable in various colors) and surfaces (from matt to glossy, sealed or patinated). All other lights are optionally available in light or dark concrete and can be individually combined with gold, silver or copper interior fittings. You also have a free choice of cable color.

What materials are used for GANTlights?

GANTlights works with high-quality, high-contrast materials: concrete (hand-cast, each piece unique), copper (genuine copper sheet with nano-sealing, warm sheen), brass (timelessly elegant with gold shimmer), oxidized brass (golden-brown textured patina), oxidized copper (turquoise-green patina), oak (natural wood, warm and durable), Corten steel (rust look full of character, sealed), stainless steel (brushed, minimalist) and gold (elegant accents).

What are the advantages of concrete lamps?

Concrete lamps offer numerous advantages: Unique design (rustic industrial look meets elegance), versatile combination (fits in with modern, Scandinavian and industrial furnishing styles), durable (robust material with a long service life), natural feel (each lamp is unique due to the concrete structure), trend material (concrete is all the rage in interior design) and high value (statement piece for a special atmosphere).

How do I look after a concrete lamp properly?

Concrete lamps are easy to care for: Dust regularly with a damp cloth and remove any dirt. For stubborn stains, the lamp can simply be sanded down with 120K sandpaper. Avoid vinegar or citrus cleaners (they attack the surface). For long-term protection, the surface can be sealed with oil or wax. Wipe with a dry cloth or allow to air dry.

Are concrete lamps heavy?

Yes, concrete lamps have a certain dead weight due to the material, but they are lighter than you might think due to the thin walls of the special concrete. However, this ensures stability and conveys value. In the case of pendant luminaires and hanging lamps, the ceiling attachment is designed accordingly. GANTlights pays attention to a balanced ratio between material thickness and weight so that the lamps can be securely mounted.

How do concrete lamps look in different interior styles?

Concrete lamps are extremely versatile: modern/minimalist (perfect complement to clean lines), industrial/loft (harmonizes with brick, steel and raw surfaces), Scandinavian (contrast with light wood tones), elegant/noble (combined with brass or gold for a luxurious ambience), rustic (goes well with solid wood furniture). Tip: Combine concrete lamps with soft textiles (cushions, rugs) for a harmonious overall impression.

Which light sources fit in GANTlights lamps?

All GANTlights sockets have standard sizes such as E14 or E27. You can use all commercially available light bulbs and LED bulbs with the appropriate thread. For the B3 and T2 lamps, you need a spherical E14 drop-shaped bulb, which is available at any DIY store. The bulbs are not included in the scope of delivery, so you can select them according to your personal lighting preferences.

What is the maximum wattage of the lamps?

We recommend using a maximum of 40 watt bulbs in the lamps. When using LED light sources, you can achieve the same brightness with significantly fewer watts (e.g. 8-12 watt LED) as with conventional 40 watt light bulbs – with significantly lower energy consumption.

Are the lamps dimmable?

All lamp models are dimmable. The built-in LED light of the C1 lamp is also optionally available dimmable. Please make sure that your dimmer switch is LED-compatible. You can find a list of compatible dimmers here.

How bright are the lights?

As the concrete is opaque, the light shines very directionally from the lamp. Due to the gold coating on the inside, however, the light cone is relatively large and, depending on the height of the lamp, is diffused far into the room. The coating also colors the light in a very pleasant warm yellow-gold. In addition, you can determine the brightness yourself with the strength of the bulbs used.

The different internal coatings – gold, silver and copper – have an influence on the color of the light emitted.

How many lamps do I need for my table?

For the pendant lights, B1, B2, B5, B6, T1, T2 and T3, we recommend one light up to a table length of 100 cm, two lights up to 160 cm, three lights up to 240 cm and so on. As a rule of thumb, we recommend installing one light for every 80 cm of table length.

How can I imagine Lumen?

Lumen (lm) describes how bright a lamp really is. The higher the lumen value, the brighter the light.
In the past, watts were used as a guide – today this no longer works because modern LEDs are just as bright (or brighter) at much lower wattages.

👉 What counts for brightness is lumens, not watts.

How do you calculate lumens in watts?

An exact conversion is not possible. But there are tried and tested comparative values that are perfectly adequate as a guide.

The best way to visualize lumens is to compare them with the brightness of classic light bulbs.

Lumen-watt comparison – LED compared to the classic incandescent lamp

• approx. 250 lm
  ≙ previously approx. 25 W incandescent lamp (e.g. small accent lighting)

• approx. 470 lm
  ≙ previously approx. 40 W incandescent lamp (basic lighting for small areas)

• approx. 800 lm
  ≙ previously approx. 60 W incandescent lamp (classic living room brightness)

• approx. 1,050 lm
  ≙ previously approx. 75 W incandescent lamp (bright room lighting)

• approx. 1,500 lm
  ≙ previously approx. 100 W incandescent lamp (very bright areas, work)

LED, halogen and incandescent lamp in direct comparison?

👉 S ame brightness – significantly less power consumption with LED.

Why are these only approximate values?

The actual lighting effect depends, among other things, on:

• Beam angle (spot or wide)

• Lamp shape (reflector, diffuse)

• Surface (clear or matt)

• Dimmability

• Quality and manufacturer

  However, the specifications are very useful for quickly getting a feel for the brightness – which is exactly what they are intended for.

Briefly summarized

• Watt = power consumption

• Lumen = brightness

• LEDs need far fewer watts for the same amount of light

• Lumen/watt comparisons are orientation aids, not exact formulas

The lumen, beam angle and lighting effect of our luminaires are precisely coordinated – for clear, architectural lighting without glare.
