Mini LED Downlights & Spotlights (4W–9W) for Display Cases, Cabinets & Tight Spaces
Introduction – When Standard Downlights Are Too Big, You Need Mini LEDs
You have a jewellery display counter – each shelf needs a tiny, focused light, but the cabinet ceiling is only 40mm deep. Or you’re lighting a model train diorama, a museum vitrine, or a library bookshelf where standard Ø75mm downlights would overpower the space. The market is full of “mini” downlights that are either dim (poor efficacy) or run hot (short life).
Our LD-03-988 series solves the small‑space lighting problem. With 4W SMD (98805), 6W COB (98806), and 9W COB (98807) options, cutouts from Ø35mm to Ø55mm, and beam angles 15°/24°/36°, these mini downlights deliver genuine 80+ LM/W efficacy in a body small enough to fit almost anywhere.
Common Questions About Small Downlights – Answered
Q1: “What’s the smallest cutout size available in a decent quality LED downlight?”
Many cheap “puck lights” have cutouts as small as 25mm, but they use low‑efficiency SMD chips, have terrible colour rendering (CRI <70), and overheat within an hour. Our LD-03-98805 requires a Ø35mm cutout – that’s smaller than a US quarter. Yet it produces 4W at 82 LM/W (~328 lumens) with CRI 80, and uses a proper aluminium housing for heat dissipation. It’s the smallest truly professional downlight we offer.
Use it for:
- Jewellery display cabinets (under‑shelf lighting)
- Model or collectible displays (train sets, Lego builds)
- Caravan/RV ceiling lights
- Small retail kiosks
For slightly larger spaces, the 98806 (Ø45mm cutout) and 98807 (Ø55mm cutout) provide more power while still being much smaller than standard downlights.
Q2: “SMD vs COB – which is better for small downlights?”
Both have advantages, which is why we offer both in the 988 series:
- SMD (98805 4W) – Surface‑mounted diodes. Better for very small fixtures because the chips are flat and require less depth. SMD can achieve good mixing of light, but may have slightly less punch than COB. For general ambient light in a small space, SMD is fine.
- COB (98806/98807 6W/9W) – Chip‑on‑board. A single dense array of tiny LEDs gives a more uniform, intense beam with better centre‑to‑edge consistency. COB is superior for accent lighting where you need a crisp, defined spot. It also typically has better thermal performance because the entire chip is bonded directly to the substrate.
For jewellery showcases: use the COB versions (6W or 9W) for a bright, sparkling effect on diamonds and gold. For under‑cabinet ambient lighting in a kitchen: the SMD 4W is sufficient and cost‑effective.
Q3: “How do I avoid glare when using mini downlights in a low ceiling?”
Because mini downlights are small, they are often installed in very low ceilings (e.g., inside a display cabinet with only 200mm height). In such situations, the light source is very close to the eye level of the viewer. To reduce glare:
- Choose a narrower beam angle (15° or 24°) so the light goes straight down, not sideways.
- Recess the fixture as deeply as possible – our 988 series has a reasonable recess depth (the COB is set back from the rim), but for extreme low‑height displays, consider adding a honeycomb louver (available as an accessory).
- Use a lower power (4W instead of 9W) and increase the number of fixtures for even coverage without a single bright spot.
Our beam angle options (15°/24°/36°) give you control. For a cabinet that is only 30cm tall, 15° will keep the light inside the cabinet without spilling into the viewer’s eyes.
Q4: “Can I use these mini downlights in a sloped ceiling or as a wall washer?”
The LD-03-988 series is fixed, not gimbal‑adjustable. For straight‑down applications (horizontal ceiling), they work perfectly. For sloped ceilings or wall washing, you would need an adjustable gimbal model. However, because these are so small, you can also install them at a slight angle by using a wedge‑shaped mounting ring (not included, but available from third‑party suppliers). For most display cabinet and under‑shelf applications, a fixed downward angle is exactly what you need.

Installation Tips for Small Downlights
- Check your void depth – The 98805 (50mm tall) needs at least 55mm of ceiling cavity. The 98806 (62mm) needs 65mm, and the 98807 (75mm) needs 80mm. In display cabinets, you often have less than 100mm – all three will fit easily.
- Use a template for multiple fixtures – When drilling many 35mm holes in a row (e.g., along a shelf edge), use a paper template to ensure perfect alignment. The small size means even 1mm misalignment is visible.
- Consider colour temperature for product display – For jewellery, 4000K (neutral white) makes diamonds sparkle and gold look warm. For food displays (bakery, deli), 3000K (warm white) enhances appetite appeal. For medical or technical inspection, 6000K (cool white) shows detail best.
- Driver placement – The integrated driver is inside the housing (for AC input). If you have a metal display cabinet that gets hot, ensure adequate airflow around the fixture – the aluminium body needs to radiate heat. For very enclosed spaces, consider using an external driver version (custom order).
Where to Use Each Model
| Model | Best Application |
|---|---|
| 98805 (4W SMD) | Under‑cabinet lighting in kitchens, inside glass display shelves, model train layouts, RV interior lights |
| 98806 (6W COB) | Jewellery showcases, watch display counters, museum vitrines, retail shelf highlighting |
| 98807 (9W COB) | Higher ceilings in small rooms (e.g., powder room, pantry), retail kiosks, entrance canopy lights |
Why Choose the LD-03-988 Series Over Generic Puck Lights?
- Genuine Sanan chips – No cheap no‑name LEDs that turn blue after 6 months.
- Aluminium housing – Not plastic. Heat is managed properly, so lumen maintenance is high.
- CRI 80 – Colours look true, not washed out.
- Multiple beam angles – You’re not stuck with a single floody beam.
- Professional finish – White matte trim looks clean, not like a toy.
Generic puck lights from home improvement stores typically have CRI <70, plastic bodies that yellow, and no beam angle choice. For commercial applications where appearance and reliability matter, the 988 series is the correct choice.
Big Performance in a Tiny Package
Small spaces demand small fixtures – but not at the cost of light quality. The LD-03-988 series gives you professional‑grade illumination in cutouts as small as 35mm. From jewellery showcases to model displays to under‑cabinet kitchen lighting, these mini downlights provide reliable, glare‑controlled, high‑CRI light wherever standard fixtures simply won’t fit.
