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.Aluminium body, 11013056mm.

This module appears twice in our catalogue the sameproduct and the same part numbers on two pages under different names. Both sell the same module.

And the two sources for its light output disagree:

The datasheet held for this listing is a superseded revision, which is the likeliestexplanation an earlier, brighter specification. We have published the lower, currentrecord figures, and if the output is load-bearing on your specification, ask us and wewill get the current sheet from Domus.

Five colour temperatures, including 2700K

• 2700K 1,002lm. Extra warm, and rare in this catalogue. Bedroomsand hospitality.
• 3000K 995lm. The domestic default. Note it is fractionally thedimmest setting, not the warmest-and-dimmest as you might expect.
• 4000K 1,098lm. Kitchens, bathrooms, offices.
• 5000K 1,163lm. The brightest. Task areas.
• 5700K 1,145lm. Workshops and inspection.
• The spread across all five is about 17% so switching colour does change thelevel, but not dramatically.

The beam angle is a variant, not a setting

• Four part numbers 15, 24, 36 and 60.
• 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.
• The lumen figures above are for the module, not per beam angle. A 15 versionconcentrates the same output into a much smaller area, so it will look far brighter on what it hits.
• Because the module is replaceable, the beam is reversible swap it laterwithout touching the ceiling.

13W or 9W?

• 13W suits higher ceilings and commercial spaces, or where fewer fittings arewanted.
• 9W is the more common residential choice standard ceilings, hallways,bedrooms.
• Both are 49.956mm and take the same frames, so thewattage can be changed later by swapping the module alone.
• The DALI versions of both are 68mm deep.

The cutout comes from the frame, not from this module

• The module is 49.9mm and clicks into a frame; the frame goes in theceiling.
• CELL-S1 / S2: 7075mm. CELL-D75 frame:75mm. CELL-D90 frame: 90mm.
• Its datasheet’s cutout line describes a rectangular SLOTCELL frame adifferent product. Do not cut to it.
• Tell us the frame and we will confirm the cutout before anyone marks a ceiling.

The retrofit case

• 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, depending onheight.
• Aluminium body, which is a better heatsink than a polymer housing and heatis what determines how an LED ages.
• The module is the replaceable part, so a failure or a change of colour or beamleaves the frame and the ceiling untouched.

Where it works

• Retrofit into existing MR16 downlight frames check the height.
• New installations with a CELL frame S1, S2, D75 or D90.
• Higher ceilings and commercial fit-outs.
• Rooms wanting genuine 2700K warmth.
• Not a complete fitting the frame is separate.
• Do not cut to the datasheet’s cutout line.

Specifying it

13W COB LED lamp module and driver set, aluminium.49.9mm module in a 11013056mm body.Five switchable colour temperatures 2700K (1,002lm) / 3000K(995lm) / 4000K (1,098lm) / 5000K (1,163lm) / 5700K(1,145lm), by dip switch.Beam angle chosen at order: 15, 24, 36 or 60.CRI 80, dimmable, 50,000hrs,200240V. IP44 from the underside once installed.

The frame is sold separately and the cutout comes from it. The datasheet held is a superseded revision quoting higher outputs (1,2001,350lm);we have published the current record figures. This module also appears on a second listing inour catalogue. Warranty 3 years.

Questions

How bright is it?

Between 995 and 1,163 lumens depending on the colour setting brightest at 5000K and fractionally dimmest at 3000K. Worth knowing: the datasheet held for this listing is a superseded revision quoting higher figures of 1,200 to 1,350 lumens. We have published the lower, current record figures. If the output is load-bearing on your specification, ask us and we will get the current sheet from Domus.

Does the beam angle change the brightness?

Not the total output, but very much what you see. Those lumen figures are for the module; a 15 version concentrates the same light into a far smaller area, so it will look much brighter on what it hits and leave everything else darker. Choose the beam for the effect rather than the number.

What size hole does it need?

That comes from the frame, not the module the module itself is 49.9mm. A CELL-S1 or S2 frame takes 7075mm, the CELL-D75 frame 75mm and the CELL-D90 frame 90mm. Do not use the figure on the datasheet: its cutout line describes a rectangular SLOTCELL frame, which is a different product.

Should I choose the 13 W or the 9 W?

13W for higher ceilings and commercial spaces, or where you want fewer fittings. 9W is the more common residential choice for standard ceilings, hallways and bedrooms. Both modules are 49.9 56mm and take the same frames, so you can change the wattage later by swapping the module alone.

Why does this module appear twice on your site?

Because it is listed twice the same product with the same part numbers on two pages under different names. Both sell the same module and you will get the same item. This page carries the lumen and material figures; the other does not, which is one of the practical costs of a duplicate listing. We have flagged it for tidying.

Will it replace my existing halogen downlights?

In most cases 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.

What is the module made of?

Aluminium, which is a better heatsink than a polymer housing and heat is what determines how an LED ages. That figure is recorded on this listing and not on its duplicate, which is worth knowing if you are comparing the two pages.
