Cologne LED · Titan Spots series · cut-out 72–85 mm

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.

CRI ≥ 98 (spectrometric) cut-out 72–85 mm IP20 or IP65 DALI-2 or trailing edge 14 bezel variants 5-year warranty

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

Ra 98 spectrometrically measured, saturated red at R9 = 93
5 years manufacturer warranty, service life rated at 50,000 hours (L80B10)
Hundreds installed, from KNX projects to a ballroom on a cruise ship

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 lm

Yellowish-warm like an incandescent lamp. Living rooms, bedrooms, hotel lobbies, bars, restaurants in the evening.

Dim2Warm 2700K–2000K

500 lm

Turns 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 lm

Warm, but crisper in the whites. Kitchens, bathrooms, hallways, shops, open-plan kitchens.

4000K neutral white

700 lm

Plain 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.

At CRI 80 reds and pinks look dull and brownish. At Ra 98 they stay saturated, which is what decides the sale in hospitality and retail.

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

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.

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

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.

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.

What cut-out size do the Titan Spots need?
Every LED downlight in this series fits a cut-out of 72 to 85 mm. The round bezels measure Ø90 mm on the outside, the square ones 90x90 mm. If your existing cut-outs sit in that range, you can swap without any rework.
Which colour temperature suits which room?
2700K reads yellowish-warm like an incandescent lamp and suits living rooms, bedrooms, bars and hotel lobbies. 3000K is a little crisper and suits kitchens, bathrooms, hallways and retail spaces. 4000K is neutral white and belongs in offices, workshops and practices. Dim2Warm shifts warmer as it dims, from 2700K down to 2000K, much like an incandescent lamp. Use only one colour temperature within a single sightline.
DALI or an ordinary dimmer?
An ordinary LED dimmer working on the trailing edge is enough as long as all luminaires in a room dim together. DALI pays off when single luminaires need separate control or scenes are programmed centrally, and it needs its own bus line and a gateway for that. The trailing-edge version can also be tied into KNX through a universal dimming actuator, though then by channel rather than by luminaire.
IP20 or IP65?
IP20 is enough in dry rooms. IP65 is protected against water jets and is required in bathrooms, showers, steamy kitchens and sheltered outdoor areas. The IP65 bezels are fully sealed, which is why the fixed version cannot be tilted.
What happens if a part fails after some years?
Then only that part is replaced. Bezel, LED module and driver are three separately available components. A failed driver therefore does not cost a new housing, and swapping a bezel for looks does not need a new ceiling cut-out. That lowers the follow-up cost in large installations and avoids electronic waste.
Can I change the bezel later?
Yes. Bezel, LED module and driver are separate parts. If the interior style changes, only the bezel is swapped and the cut-out stays. The same applies to a fault: the whole luminaire does not have to be replaced.

Who stands behind this selection

Oliver Rothweiler Cologne LED · commercial lighting for 12 years

I have followed this series since it launched and have specified it as the recessed lighting in several hundred fittings. Two kinds of project keep coming back.

One is smart building: the spots sit on the bus through the KNX-DALI interface, get individual addresses and run in scenes. What counts here is that every luminaire responds cleanly and that the dimming curve stays identical across all of them.

The other is contract work under rough conditions. In a large ballroom on a cruise ship what mattered was that the bezel does not rattle under vibration and that the modules keep running reliably over long operating hours. That is exactly what the modular design is built for.

Not sure which one fits?

Tell us the room, the ceiling height and the dimming you already have, and we will suggest the right version. The phone is quickest.
