Domus PLEX-Rgb+tune/Wht 21W P/M COB Strip 24V IP54 840LED/M 50M Pack

The Domus PLEX-RGBTW is a 24 V COB LED strip — 21 W per metre, 840 LEDs per metre, IP54, 50 m pack, combining RGB colour with tuneable white.

⭐⭐ Fifty metres of this is 1,050 W — and that is the smaller half of the problem

• ⭐ At 21 W per metre, fifty metres draws 1,050 W — ⭐ the largest load of any fifty-metre order in the catalogue.
• ⭐ The run limit is 5 m one-end and 10 m two-end, so fifty metres is five runs.
• ⭐⭐ AND EACH RUN NEEDS A CONTROLLER AS WELL AS A DRIVER. ⭐ RGBTW is four channels, and something has to address them. ⭐ So a fifty metre order is five drivers of about 250 W plus the control equipment to match — and if the runs are to be independently controllable, five separate zones.
• ⛔ NONE OF THAT APPEARS ON THIS PAGE. ⭐ The listing sells strip; the driver, the controller, the profile and the zoning are all separate decisions that nothing prompts you to make.
• ⭐ THIS IS THE ORDER WHERE A CONVERSATION BEFOREHAND SAVES THE MOST. ⭐ Tell us the runs, how you want to control them and whether the zones are independent, and we will specify the whole package.

⭐ Is fifty metres of colour-changing strip actually what the project wants?

⭐ Worth asking plainly. ⭐ RGBTW costs more per metre, draws four times the load of a 5 W white strip, needs a controller, fragments into five runs and adds a layer of commissioning — all to deliver a capability most of a building will use rarely. ⭐ THE PATTERN THAT USUALLY WORKS BETTER: colour-changing strip in the two or three places it will be used — a bar front, a feature wall, a pool surround — and plain tuneable white everywhere else. ⭐ Both are dotless at 840 and 640 LEDs per metre, and matching the white temperature makes them read as one system. ⚠ Fifty metres of RGBTW throughout is the simplest order and rarely the best design.

⚠ And plan for blue being quiet

⭐ On the verified sheet for the IP67 version, green measures 260 lm per metre and blue 55 — ⭐ a factor of 4.7, which is the eye's own sensitivity curve rather than a fault. ⚠ Across fifty metres a blue scene will read far quieter than a green or white one. ⭐ If the scheme leans on blue, that is worth designing around rather than discovering.

⛔⛔ Aluminium heat sink, mandatory — and at 21 W it is not marginal

⭐ The sheet voids the warranty without one. ⭐ At 21 W per metre this is the hottest strip in the range by some distance — ⭐ more than four times the 5 W strip's heat in the same board area. ⭐ The aluminium is not a technicality here; it is what keeps the LEDs at a temperature where they last. ⭐ Fifty metres of strip means fifty metres of profile.

Where it works

• ⭐ Large venues genuinely using colour — ⭐ bars, clubs, retail.
• ⭐ Where five controlled zones are wanted.
• ⭐ Where good white matters as much as colour.
• ⚠ Rarely as a blanket choice — ⭐ mix with white strip.
• ⛔ Not without controllers and profile.

Specifying it

RGBTW COB LED strip, IP54, 50 m pack. 21 W per metre at 24 V DC, 1,050 W total. 840 LEDs per metre, dotless. Separate tuneable white channel. Continuous run 5 m one-end, 10 m two-end. Five drivers and matching controllers required. Aluminium heat sink mandatory. 3-year warranty. ⭐⭐ FIFTY METRES IS 1,050 W, FIVE RUNS, FIVE DRIVERS AND FIVE CONTROLLERS — because RGBTW needs something to address four channels at every feed. NONE OF THAT APPEARS ON THE PAGE. ⭐ IT IS ALSO WORTH ASKING WHETHER FIFTY METRES OF COLOUR-CHANGING STRIP IS WHAT THE PROJECT WANTS: the pattern that usually works better is RGBTW in the two or three places colour will actually be used, and plain tuneable white everywhere else. Both are dotless, and matching the white temperature makes them read as one system.
