Recessed Spotlights dimmable
LED Downlights and Recessed Spotlights with CRI 98
These LED downlights are a kit of bezel, LED module and driver: round 90mm or square 90x90mm, IP20 or IP65, dimmed via DALI-2 or an ordinary wall dimmer. Four colour temperatures, measured colour rendering of Ra 98. Call them recessed downlights, ceiling spotlights or LED spotlights: it is the same luminaire, set flush into the ceiling and run on 230V.
Find the right LED downlight in three questions
Three answers are enough to pick the right model from the series: the brightness you need, the dimming already in place, and the room. All of them are high CRI downlights, so colour rendering is not part of the decision.
| Question | If this applies | Then |
|---|---|---|
| How bright? | Living room, hallway, hotel room, normal ceiling height | 8W with 500 to 700 lumens |
| Higher ceiling, wide spacing, or high illuminance at the workplace: jewellers, goldsmiths, fine handwork, retail floors | 13W with 1085 or 1115 lumens | |
| Dimmed how? | A dimmer is already there, one circuit per room is enough | Trailing edge, no bus needed |
| Single luminaires controlled separately, scenes set centrally | DALI-2, bus line and gateway | |
| Which room? | Dry indoor space | IP20, adjustable |
| Bathroom, shower, steamy kitchen, outdoors | IP65, sealed and fixed |

| LED spotlights 13W, trailing edge | 2700K, 3000K | 1085 / 1115 | Trailing edge | IP20 and IP65 |
Every downlight in this series shares the same 14 bezels and the same cut-out. Bezel, LED module and driver can be reordered individually.
Four colour temperatures, one recessed spot
For jewellery, fine handwork and retail floors, EN 12464-1 sets out its own tables with higher requirements for illuminance and colour rendering. That is where 13 watts and Ra 98 pay off together.
2700K extra warm white
600–1085 lmYellowish-warm like an incandescent lamp. Living rooms, bedrooms, hotel lobbies, bars, restaurants in the evening.
Dim2Warm 2700K–2000K
500 lmTurns warmer as it is dimmed, the way an incandescent lamp does. For restaurants, bedrooms and anything that should feel cosy at night.
3000K warm white
650–1115 lmWarm, but crisper in the whites. Kitchens, bathrooms, hallways, shops, open-plan kitchens.
4000K neutral white
700 lmPlain and bright. Offices, workshops, practices, anywhere precise work is done.
CRI 80 against CRI 98 – see the difference yourself
Drag the slider in each of the three scenes. Watch the critical test colours red (R9), turquoise (R5) and skin tones (R13). Ra 90 counts as high quality in the industry, and EN 12464-1 asks for at least Ra 80 where colour rendering matters. What was measured here is 98.
The comparison images simulate the spectral effect; they are not product photography. The measured values come from our own spectrometer readings, see below.
The technical detail
Measurements What the spectrometer measures
Measured on the 8W module in 2700K: colour rendering index Ra 98, extended index Re 97, saturated red R9 = 93. Under TM-30-20 that gives Rf 96 and Rg 100; the colour temperature is 2786 K with a Duv of 0.0015. On top of that, CQS 98 and TLCI 98, with a peak wavelength of 629 nm.
R9 is the value that decides quality. It describes saturated red and often drops below 20 on standard LEDs while the Ra figure still looks respectable. At 93, skin tones, meat, wood and fabrics appear the way they do in daylight.

Dimming DALI-2 or trailing edge
| Property | Trailing edge | DALI-2 |
|---|---|---|
| Wiring | the existing 230V line | an extra bus line to the gateway |
| Single luminaires | no, the whole circuit dims | yes, each luminaire has its own address |
| Luminaires per circuit | a small group, limited by the dimmer | up to 64 addresses per segment |
| Cost | one dimmer | gateway plus commissioning |
| Typical for | flats, practices, shops | hotels, offices, KNX projects |
The full comparison with advantages and drawbacks sits on the product pages of the 13W models.
IP rating IP20 or IP65
| Property | IP20 | IP65 |
|---|---|---|
| Suitable for | dry indoor spaces | bathroom, shower, steam, sheltered outdoors |
| Adjustable | yes | depends on the bezel; the sealed version is fixed |
| Bezel colours | white, black, matt stainless steel, hotel bezel | white, black, matt stainless steel |
In a bathroom the distance to the tub or shower decides which IP rating applies. In zones 1 and 2, LED downlights rated IP65 are the safe choice.
Sustainability Repair instead of replace
Bezel, LED module and driver are three separate parts, neither glued nor soldered. If a driver fails, the driver is replaced. If a module fails, a new one goes into the existing bezel. If the ceiling should be white instead of black later, only the bezel changes and the cut-out stays. Across a project with a hundred spots, that decides the follow-up cost of the coming years.
