The Domus CELL-13 is a 13W plug-and-play LED lamp module and driver set withfive switchable colour temperatures and a choice offour beam angles 15, 24, 36 or 60.

Five colour temperatures, not three and one of them is warmerthan anything else in this range.

The 2700K step is the one worth noticing. Most switchable fittings jump from3000K straight to neutral white, so a room that wants genuine incandescent warmth has no option.This one has it, set by a dip switch before installation.

The beam angle is a variant, not a setting

• 15, 24, 36 or 60 and they are four different partnumbers. You choose the beam when you order and it cannot be changed afterwards.
• 15 a tight accent. Artwork, a single object, a very high ceiling.
• 24 a defined pool. Joinery, a bench, a display shelf.
• 36 the general-purpose choice on a standard ceiling.
• 60 a wide wash. General room lighting, fewer fittings.
• Because the module is replaceable, the beam is not permanent a module can beswapped later without touching the ceiling. That is the whole argument for the CELLsystem, and it is the reason to buy modules rather than sealed downlights.

What “plug and play module and driver set” actually means

• It is a lamp and its driver, not a complete fitting. The module clicks into a frame,and the frame is what goes in the ceiling.
• As a retrofit it replaces an MR16 halogen lamp and its transformer together pull both out, put the CELL lamp and driver in. It suits most MR16 downlight frames, dependingon height, which is the constraint to check.
• As a new installation it pairs with a CELL frame the single CELL-S1 or thetwo-light CELL-S2, in black or white.
• The module is the replaceable part. When it fails, or when the beam or colour needsto change, the frame and the ceiling stay untouched. On a commercial fit-out that is the differencebetween a maintenance job and a rebuild.

The cutout figure on its datasheet is not this product’s

The sheet’s cutout line reads L190mm x W100mm SLOTCELL-2-13W a rectangular two-light slot frame, not this round module.

• Do not cut to that figure. The module itself is 49.9mmand 56mm deep.
• The cutout comes from the frame you put it in, not from the module: a CELL-S1 orCELL-S2 takes 7075mm, or 85mm for theK75 and P75.
• Tell us the frame and we will confirm the cutout before anyone marks a ceiling.

The numbers

• 13W COB LED, CRI 80, 50,000hours.
• Dimmable, on 200240V, 5060Hz.
• Module 49.956mm; the driver is supplied with it.
• IP44 from the underside of the downlight once installed into the ceiling the datasheet’s own wording, and our record shows a bare IP44. It means protection from the roomside, not a sealed fitting in the void.
• 9951,163lm depending on the colour setting 995lm at3000K rising to 1,163lm at 5000K. Those figures are recorded on this module’sother listing in our catalogue, not on this one. A superseded datasheet quotes higher numbers(1,2001,350lm); we have published the current record figures. The output is for the module:a 15 version concentrates the same light into a much smaller area.

Module or complete downlight?

• Buy the module and a frame where the beam or colour may need to change, where theceiling is going in now and the fitting later, or where maintenance access matters.
• Buy a complete CELL downlight (the D75, D90, T75 or T90) where you want one partnumber and a known cutout.
• There is also a DALI version of this module for buildings with a digital controlsystem. Ask us if that is what you need.

Where it works

• Retrofit into existing MR16 downlight frames check the height.
• New installations with a CELL-S1 or CELL-S2 frame.
• Commercial fit-outs where modules will be maintained rather than replaced whole.
• Rooms wanting genuine 2700K warmth rare in this catalogue.
• Not a complete fitting the frame is separate.
• Do not cut to the datasheet’s cutout line; it belongs to a different frame.

Specifying it

13W COB LED lamp module and driver set. Module49.956mm.Five switchable colour temperatures 2700K / 3000K / 4000K / 5000K /5700K, by dip switch. Beam angle chosen at order: 15, 24, 36 or60. CRI 80, dimmable,50,000hrs, 200240V 5060Hz. Black. IP44 from the underside once installed not a sealed rating for the void.

The frame is sold separately (CELL-S1 single or CELL-S2 two-light), andthe cutout comes from the frame: 7075mm, or 85mm for the K75 andP75. The datasheet’s cutout line (“L190 x W100mm SLOTCELL-2”) belongs to adifferent, rectangular frame do not cut to it. Lumen output is not recorded in anysource. Warranty 3 years.

Questions

What does “5 colour temperatures” give me that three does not?

A 2700K setting, mostly. Most switchable fittings in this catalogue run 3000, 4000 and 5000 or 5700K so a room that wants genuine incandescent warmth has no option. This one adds 2700K at the warm end and 5700K at the cool end, set by a dip switch before installation. In a bedroom or a restaurant the 2700K step is a visible difference, not a marketing one.

Can I change the beam angle later?

Not on a given module the four beam angles are four different part numbers, chosen at order. But you can swap the whole module later without touching the ceiling, which is the entire argument for the CELL system. That makes the beam a reversible decision even though it is not a switch.

Which beam angle should I choose?

36 is the general-purpose choice on a standard ceiling. 15 is a tight accent for artwork, a single object or a very high ceiling. 24 gives a defined pool over joinery, a bench or a display shelf. 60 is a wide wash for general room lighting with fewer fittings. Tell us the ceiling height and what you are lighting and we will suggest one.

What size hole does it need?

That comes from the frame, not the module the module itself is only 49.9mm. A CELL-S1 or CELL-S2 frame takes 7075mm, or 85mm for the K75 and P75. Do not use the figure on the datasheet: its cutout line reads “L190 x W100mm SLOTCELL-2”, which is a rectangular two-light slot frame and not this product at all.

Will it replace my existing halogen downlights?

In most cases, yes that is what it is designed for. You remove the MR16 halogen lamp and its transformer together and put the CELL lamp and driver in their place. It suits most MR16 downlight frames, with height being the constraint to check. Tell us what is up there now and we will confirm.

Should I buy the module or a complete downlight?

The module plus a frame where the beam or colour may need to change, where the ceiling goes in now and the fitting later, or where maintenance access matters in a commercial fit-out that is the difference between changing a module and rebuilding a ceiling. A complete CELL downlight (D75, D90, T75 or T90) where you want one part number and a known cutout.

How bright is it?

No lumen output is recorded in any source we hold, and on this product that gap matters more than usual: a 15 and a 60 version of the same 13W behave very differently, and the beam angle is chosen at order. Ask us and we will get the figures from Domus for the beam you are considering.
