The Domus PANEL-BLT-DIM is a 10W backlit LED panel TRIAC dimmable, tri-colour switchable, with a harmonicfilter for flicker-free operation, white frame and opal diffuser.

TRIAC the reason this one is different

• The rest of this panel family dims by DALI or not at all. This one dims byTRIAC which is the ordinary mains dimmer already on most walls.
• That is the practical difference between a commercial and a domesticinstallation. DALI needs a control system, a control cable to each fitting and someoneto commission it. TRIAC needs a dimmer switch.
• The trap on a small load: 10W is very little for a mains dimmer. Many TRIAC dimmers specify a minimum load well above a single 10W fitting, andbelow it you get flicker, a dead band at the bottom of the range, or a fitting that will not strike atall. Several panels on one dimmer solves it; one panel on its own is the case tocheck.
• Ask us for the dimmer you intend to use and we will confirm compatibility before youorder TRIAC compatibility is genuinely brand-specific, and it is not somethingto discover after the ceiling is closed.

Two flicker questions, and they are not the same one

Domus’s flicker-free claim addresses the first. A dimmable fitting has asecond flicker question that only appears at low levels, and nothing published addresses it. On a fitting sold specifically for dimming, that is the gap worth naming.

What this listing does not publish

No lumen output, no dimensions, no IP rating and no warranty. Its singlevariant is named 303, which is the 300 300mm module a sizecode used as a variant name, which is not obvious to a reader. At the family’s8894lm/W, 10W suggests roughly 880940lm. An inference,not a published figure.

What is published

Where it works

• Domestic and small-commercial ceilings where DALI is overkill.
• Hallways, laundries and small offices the 300mm module.
• Rooms used for video the flicker filter at full output.
• Not one panel alone on a mains dimmer without checking the minimum load.
• Not in wet areas no IP rating is published.

Specifying it

10W backlit LED panel, 300 300mm module. TRIAC dimmable. Tri-colour switchable byDIP switch on the cable. White frame, opal diffuser. Harmonic filter, flicker-free. TRIAC IS WHY THIS ONE IS DIFFERENT the rest of the family dims by DALI or not at all, and DALIneeds a control system, a cable to each fitting and commissioning. TRIAC needs a dimmer switch. THETRAP IS THE LOAD: 10W is very little for a mains dimmer, many of which specify a minimum well above asingle fitting below it you get flicker, a dead band, or no strike at all. Tell us the dimmer and wewill confirm compatibility first.

Questions

What makes this one different from the other panels?

It dims by TRIAC. The rest of the family dims by DALI or not at all, and TRIAC is the ordinary mains dimmer already on most walls. That is the practical difference between a commercial and a domestic installation: DALI needs a control system, a control cable to each fitting and someone to commission it; TRIAC needs a dimmer switch.

Is there a catch?

The load. 10W is very little for a mains dimmer, and many TRIAC dimmers specify a minimum load well above a single 10W fitting below it you get flicker, a dead band at the bottom of the range, or a fitting that will not strike at all. Several panels on one dimmer solves it; one panel on its own is the case to check.

How do I avoid that?

Tell us the dimmer you intend to use and we will confirm compatibility before you order. TRIAC compatibility is genuinely brand-specific, and it is not something to discover after the ceiling is closed. It is a two-minute conversation that prevents the most common fault on a dimmed LED install.

Does the flicker-free claim cover dimming?

Not as published, and the distinction is worth understanding. There are two flicker questions and they are not the same one. At full output, flicker comes from driver ripple and harmonic distortion which the harmonic filter addresses, and that is what removes rolling bands on camera. When dimmed, flicker comes from the interaction between dimmer and driver, shows as visible pulsing especially at low levels, and nothing published addresses it. On a fitting sold specifically for dimming, that is the gap worth naming.

What size is it?

300 x 300mm its single variant is named “303”, which is the module size used as a variant name. That is not obvious to a reader, and no dimensions are published in the fields, so it is worth stating plainly.

How much light does it give?

No lumen figure is published. At the family’s measured 88 to 94 lumens per watt, 10W suggests roughly 880 to 940 lumens. That is an inference from the 300 x 600 sibling rather than a published figure, so treat it as a guide and ask us if the number matters.

Can I use it in a bathroom?

No IP rating is published on this listing, which means we cannot say it is suitable. The other panels in the family are IP20, dry interior only, and it would be reasonable to assume the same here but on a wet-area question an assumption is not good enough. Ask us and we will confirm with Domus.
