English
You are fitting out a jewellery counter, a museum case, a pop-up at a trade show, or just a proper showcase for watches in a small shop, and someone has told you that you need a display cabinet with LED lighting built in. You search for display cabinet with LED manufacturers and land on a page full of companies whose photos all look like the same render — white gloss, blue LEDs, a faint reflection of a hand that was never there. The prices span a range so wide you assume two of them are quoting different planets. Nobody has asked what you are actually putting inside the case, which is the only question that determines whether the cabinet works or just looks expensive.
The short answer, if you want it now: the right manufacturer is the one who asks what is going inside the case, tells you the colour temperature and CRI of the LEDs in writing, names the glass type and thickness, draws the internal layout before you pay a deposit, and can show you a photo of a finished case taken on a phone in a real shop rather than a studio. Everything else — the glossy homepage, the "factory direct" badge, the forty product categories — is decoration.
Now the longer version, because this is where people quietly lose money.
This is the thing most buyers get backwards. The cabinet itself is joinery — MDF, plywood, metal frame, glass shelves, locks. Any competent workshop can build a box. What makes or breaks the result is the light: whether your product looks like itself, whether there are hot spots and glare, whether the customer's own reflection appears in the glass instead of the merchandise, and whether the LEDs will still be the same colour twelve months later when you add another case.
So when you talk to a manufacturer, spend most of your time on the lighting and less on the finish. The finish you can see immediately. The lighting you only notice once the cases are installed and it is too late to change without ripping everything out.
Ask these early. They take five minutes and they separate people who build showcases from people who stick a strip inside a box.
What colour temperature, and is it fixed? 3000K warm for gold, wood, leather, whisky, bakery. 4000K neutral for mixed retail and cosmetics. 5000–6000K cool for silver, diamonds, tech, clinical products. If they say "warm white, standard", ask for the Kelvin number. If they cannot give you one, write it into the order yourself and make them confirm it.
What is the CRI? You want Ra 90 or better for anything where colour judgement matters — jewellery, cosmetics, food, art, fabric. Ra 80 is fine for hardware, tools, general retail. Ask for the actual figure, not "high CRI". High CRI means nothing until it is a number.
Are the LEDs strip or module, and are they replaceable? This matters more than people think. A strip glued behind a fixed panel is a permanent problem when it fails or shifts colour. A modular LED bar or a strip mounted in an accessible channel can be swapped in ten minutes without dismantling the case. Insist on accessible, replaceable light sources. Always.
Where does the driver live? Drivers fail before the LEDs do. They need air, they need to be reachable, and they need to be outside the sealed display volume where heat builds up. If the driver is buried inside a closed plinth with no access panel, flag it. Also ask whether the driver is dimmable and what kind of dimming — PWM dimming at low frequency flickers on camera, and someone will always film your product.
Is there glare control? Louvred channels, frosted diffusers, and positioning the light so it hits the product not the viewer's eye. Good showcase lighting is invisible — you see the object, not the source. If the quote includes nothing about diffusion or beam control, assume you will be looking at bare dots of light reflected in your own glasses.
Heat and the sealed case. LEDs in a fully enclosed glass case dump heat into a tiny space. Heat kills drivers and it shifts LED colour over time. Ask how they manage it — ventilation, remote drivers, low-wattage runs, aluminium channels that act as heatsinks. A supplier who has thought about this will answer without looking it up.
Two things go wrong with glass, every single time.
One: reflections. Standard clear float glass has a greenish edge and throws back a visible reflection. Low-iron (extra-clear) glass costs more and removes the green cast — essential for jewellery, art, anything where colour truth matters. Anti-reflective coated glass costs more again and is worth it for museum work and high-end retail where the budget allows. Say which one you want. If you do not say, you get standard clear and you will notice the green edge on day one.
Two: safety and regulation. Shelves over a certain span need adequate thickness or they bow. Doors that the public opens need toughened glass. Cases in public venues often need laminated glass. Height matters too — a tall narrow case needs bracing or it will walk across the floor when someone leans on the door. These are not premium options, they are the baseline for a case that survives a year of public use.
| Glass choice | Best for | Cost | Trade-off |
|---|---|---|---|
| Standard clear float | General retail, storage displays | Lowest | Green edge, visible reflections |
| Low-iron / extra-clear | Jewellery, watches, art, cosmetics | Moderate | Still reflects, needs careful lighting angles |
| Anti-reflective coated | Museums, galleries, luxury retail | Highest | Coating must be cared for, specify which side |
| Toughened | Public-facing doors, shelves, floor cases | Moderate extra | Must be decided before cutting, no rework |
| Laminated | Security glazing, public venues | Higher | Heavier, thicker frames needed |
Mention this to your manufacturer before they quote. If they quote you standard glass and you later discover you needed toughened low-iron, the change order will cost more than the difference would have originally.
Display cabinet manufacturing is fragmented in a way that makes searching frustrating. There is no single dominant player because the work splits into several different trades, and most factories are good at one of them.
Retail fixture and shopfitting specialists — build complete store programmes: wall units, counters, islands, gondolas. Strong on consistency across a rollout, weak on one-off museum-grade cases. Best if you are opening multiple locations and need them all to match.
Jewellery and watch showcase specialists — understand high-CRI lighting, security glazing, lock systems, and the fact that a watch on a pillow needs a very different light from a ring in a tray. Best for high-value small goods.
Museum and gallery case makers — engineered for conservation: sealed environments, silica chambers, UV control, documented materials, tested locks. Expensive, slow, and exactly right when the contents are irreplaceable.
Exhibition and portable display case makers — lightweight, knock-down, flight-cased, fast to assemble. Best for trade shows and touring displays. Not built for twenty years of daily public use.
Metal and glass fabricators who also do cabinets — strong on structure and glass, weaker on integrated lighting and finish consistency. Fine if you have a separate lighting person.
B2B marketplaces and directories — lead generators, not makers. Useful for building a candidate list and checking rough price bands. Trading companies pose as factories here constantly, so verify properly.
Local joinery shops and sign makers — surprisingly good for one-off cases, quick turnaround, easy to visit in person. May need you to supply the lighting spec.
Geography matters less than people assume. A lot of the world's retail fixtures come out of Guangdong, Zhejiang, and Shandong in China, plus Italy, Turkey, Poland, and the US Midwest for higher-end or local-install work. Many European and American brands have their cases made overseas and fitted locally. Do not filter by country of origin — filter by whether your type of case is what they do every week.
Volume matters for a quiet reason: repeatable jigs, consistent paint batches, and spare parts that still exist in three years. If you might add more cases later, batch consistency on finish and light colour becomes part of the product, not a nice-to-have.
| Use case | Cabinet type | Lighting spec | Common mistake |
|---|---|---|---|
| Jewellery / watches | Low-profile counter, locked trays | 3000–4000K, CRI 95+, anti-reflective glass, dimmed | Too much light, wrong temperature, glare in the glass |
| Museum / gallery | Sealed case, conservation grade | 3000–4000K, low UV, strictly limited lux levels | Ignoring lux limits and heat buildup |
| Cosmetics / beauty | Wall unit or island, mirror lighting | 4000–5000K, CRI 90+, even face-level light | Overhead-only lighting that shadows the face |
| Electronics / tech | Clean lines, cable management | 5000–6000K, neat concealed runs | Visible cables ruining the look |
| Food / bakery | Hygienic finishes, easy clean | 3000K warm, high CRI for appetite appeal | Lights that run hot near food, hard-to-clean fittings |
| Trade show / pop-up | Knock-down, portable | Battery or low-voltage, fast connect | Heavy cases that two people cannot assemble |
| Pharmacy / optical | Bright, clinical, shelved | 4000–5000K, uniform shelf lighting | Uneven shelf brightness, shadowed lower shelves |
Price per linear metre looks like the comparison that matters, and it is not. Two quotes for the same run of counters can differ by a lot and both be honest, because one includes the lighting, the transformers, the glass upgrade, the locks, delivery, installation and a spare LED kit, and the other includes the boxes and a promise. Force both onto the same sheet and the picture changes fast.
Should I buy off the shelf or custom?
Off the shelf works if your space is standard and your product is generic. The moment you have odd corners, a specific brand finish, or product that needs a particular presentation angle, custom is cheaper than adapting something that almost fits. Also: off-the-shelf cases rarely let you choose the exact light temperature, and mismatched cases in the same room look wrong in a way people feel but cannot name.
How much should it cost?
I will not give you a per-metre figure because it moves with material costs, glass specification, lighting quality, and whether installation is included. Anyone quoting a fixed number without knowing your glass spec and your light spec is guessing. Get three written quotes on the same document and compare landed cost including delivery, install, and spares. That is the only honest way to find out.
Direct from a factory or through a local shopfitter?
Depends which headache you prefer. Direct saves money and you control the spec, but you own coordination — site survey, power points, delivery access, installation, snagging. A local shopfitter costs more and brings someone who knows the landlord's rules, the delivery window, and who turns up when a door hinge arrives loose. The hybrid that works best: pick the factory on component-level specs, hire locally for survey, install and first-line support.
Is cheaper always worse?
No. Cheap becomes bad when it is cheap plus vague. A low price with a named LED spec, a drawing, and a written warranty is fine. A low price with "LED lighting included" and no kelvin, no CRI, no driver location, is how you end up with a case that looks fine in the factory photos and wrong in your shop.
How long does it take?
Standard configurations can run a few weeks. Custom cases with specific glass and finishes run longer, plus time for drawings, sample approval, packing, shipping and installation. Add buffer. There is always a delay somewhere — usually the glass or the custom finish — and the install date never moves to accommodate it.
Do I need the lights dimmable?
Yes, in almost every retail situation. A case that looks perfect at 10 a.m. looks harsh at 3 p.m., and a case tuned for winter looks wrong in summer daylight. Dimming lets you tune it once the cases are actually in place, which is the only time you can judge it properly. Specify the dimming method and make sure the control is accessible to whoever actually runs the shop, not just to the installer.
What about power and cabling?
Confirm the number and position of power points before the cases are built, not after. Cases designed with the power entry on the wrong side turn a tidy install into a mess of visible extension leads. Ask for concealed cable channels and for the driver access panel to be on the side that is actually reachable once the cases are in position. This gets wrong constantly and it is entirely fixable on paper for free.
"LED lighting included" with no colour temperature, no CRI, and no mention of the driver.
Specs given as ranges instead of confirmed figures.
They agree to any size and any configuration without asking what product goes inside.
Warranty described verbally but not written into the quotation.
Only studio renders, no photos of installed cases in real shops.
Full payment upfront with no staged terms.
Fast replies before the deposit, slow replies after.
The same product photos appear on several different company sites.
They cannot tell you whether the LEDs are replaceable without dismantling the case.
No drawing provided before payment — just a price and a handshake.
Glass specification left blank or described only as "tempered glass" with no thickness.
They dodge the question of spare parts and matching future cases.
They ask what product goes inside, at what height, and who will be standing where.
They volunteer a layout drawing with dimensions and a lighting plan before the deposit.
They name the LED supplier, the kelvin, the CRI, and the driver brand.
They include a spare LED kit and spare locks in the base quote.
Their contract states what happens, and within what time, if a light section fails.
They tell you honestly that fewer lights or a warmer temperature would suit your product better. That one is rare and it is the best sign you can get.
They offer a sample panel or a finished corner mock-up for approval.
They confirm that future cases can be matched to the same finish and light batch.
Write your spec on one page: product type, case dimensions, glass type, light temperature, CRI, dimming, power location, finish, quantity, timeline, budget. Send the identical document to every supplier.
Collect five quotes minimum. Three is not enough to see the spread.
Put them on one comparison sheet: case construction, glass spec, LED spec, driver location, locks, finish, drawing included, spares, warranty, lead time, delivery, install, exclusions.
Shortlist two or three and ask for photos of installed work plus a reference you can call. Ask the reference what failed and how quickly it was fixed.
Ask for a sample panel or mock-up if the order is large enough.
Approve a physical sample for finish and light colour under your own shop lighting, not under the factory's lights. Colour judged under the wrong light is the most expensive mistake in this whole process.
Hold back a meaningful balance until installation and snagging are complete.
Get the as-built documentation: drawing, LED spec with batch numbers, driver model, wiring diagram, spare parts list. Keep it where your successor can find it.
Book a check at six months. Catching a failing driver early costs far less than replacing a whole run of cases after the finish has been discontinued.
Do not shop for a cabinet maker, shop for the person who understands what your product looks like under light. The box is the easy part. Any competent workshop can build a box. What you are really paying for is the light that makes the product look like itself, the glass that disappears instead of reflecting the ceiling, the driver placed where it can actually be reached, and the willingness to put all of that on paper before you transfer any money. Pick the supplier who names their components, draws the job, writes down the response time, and keeps the ability to match your next order. Pay a little more for that if you have to. It costs less than doing it twice.
Have you dealt with a supplier whose cases looked perfect in the photos and wrong on your shop floor, or found one that got the light right first time? Drop it below — the real details help other people reading this avoid the same trap.
1. What is a display cabinet with LED lighting?
A showcase or retail case with integrated LED lighting designed to illuminate the products inside. The LEDs may be strips, bars, or spot modules mounted in the plinth, canopy, shelves, or vertical uprights, powered by low-voltage drivers hidden in an accessible compartment.
2. What colour temperature should I choose?
3000K warm for gold, leather, wood, food and hospitality. 4000K neutral for cosmetics, mixed retail and general merchandise. 5000–6000K cool for silver, diamonds, technology and clinical products. Choose one temperature and use it consistently across all cases in the same room.
3. What CRI do I need?
Ra 90 or above for anything where colour accuracy affects purchase decisions — jewellery, watches, cosmetics, fabric, food, art. Ra 80 is acceptable for hardware, tools, and general retail displays. Ask for the actual figure in writing.
4. How do I avoid glare and reflections in the glass?
Use low-iron or anti-reflective glass, position lights to illuminate the product rather than the viewing angle, fit frosted diffusers or louvred channels, and keep the case interior darker than the surrounding space so the glass stops acting like a mirror.
5. Should the LEDs be replaceable?
Always. Specify accessible, replaceable light sources mounted in channels or modular bars, with drivers located in vented, reachable compartments. A permanently glued strip inside a sealed case becomes a permanent problem.
6. What glass should I specify?
Standard clear float for general retail. Low-iron extra-clear for jewellery, watches and art. Toughened glass for doors and shelves in public areas. Laminated glass where security glazing is required. Specify thickness based on shelf span and confirm before cutting.
7. How do I compare quotes fairly?
Put every bidder on the same sheet covering case construction, glass type and thickness, LED kelvin and CRI, driver brand and location, dimming method, locks, finish, drawing provided, spares, warranty terms, lead time, delivery, installation, and a separate column for exclusions. Compare total landed cost.
8. What warranty terms should I expect?
One to three years depending on the supplier and market. Clarify parts versus labour, response time, who pays for call-outs and shipping on replacement parts, and whether spare LEDs and drivers are supplied from the same batch.
9. How long does a custom display cabinet order take?
Standard configurations run a few weeks. Custom cases with specified glass and finishes take longer, plus time for drawings, sample approval, production, packing, shipping and installation. Build in buffer for glass lead times and finish approvals.
10. Can I add more cases later and have them match?
Yes, but only if you plan for it. Confirm the finish code and LED batch at the time of the first order, ask the manufacturer to hold records, and buy a spare LED kit from the same batch. Without those steps, a second order six months later often arrives visibly different.
