Domus PLEX-COB-5 - 5W LED Per Metre 640LED True Dotless Striplight IP54 24V - DRIVER REQUIRED

The Domus PLEX-COB-5 is a true dotless COB LED strip drawing 5 W per metre from 24 V DC, with 640 LEDs per metre, CRI ≥90, a 180° spread and IP54. Sold per metre in 3000 K, 4000 K or 5000 K.

Why the low wattage is an advantage, not a compromise

• ✅ Long runs from one feed. At 5 W/m a ten-metre run draws 50 W. The same length of 20 W/m strip draws 200 W and would need feeding from both ends.
• ✅ A small, cheap driver, which is easier to hide in joinery.
• ✅ Very little heat, which matters in a sealed profile or a tight reveal — heat is what shortens strip life and shifts its colour over time.
• ✅ Same CRI ≥90, same 640 LEDs per metre, same dotless appearance as the brighter versions. Nothing about the quality changes with the wattage.

⚠ IP54 means indoor wet areas — not outdoors

The datasheet's own footnote reads “Indoor Use Only — suitable for indoor wet areas”, and that qualifier is missing from the bare IP54 on our record.

• ✅ Bathroom, laundry, shower niche, splashback — yes.
• ⛔ Soffit, pergola, anywhere rained on — no. Domus makes an IP67 silicone-coated version of this same 5 W/m strip, and the two look identical on a reel. Tell us where it is going.

What “true dotless” changes at low output

• 640 LEDs per metre on a COB chip — chip-on-board, with the diodes under a continuous phosphor layer rather than as separate packages.
• ✅ A line of light, not a row of dots — and at 5 W/m that matters more, not less. A dim strip with visible dots reads as cheap; a dim dotless one reads as architectural.
• ✅ It is also the version most likely to sit in a shallow profile close to its diffuser, which is exactly where an ordinary SMD strip shows scalloping.
• ✅ Longer weldless sections mean fewer joins, and joins are where strip installations fail.

The driver, and the figure nobody publishes

• ⛔ Requires a 24 V DC constant-voltage LED driver — not included.
• ⛔ Maximum run length from one feed is not stated in any source we hold. At 5 W/m this strip is the most forgiving in the range, but the limit still exists. Tell us the run length and we will size the driver and set the feed points.
• ⚠ Dimming is done by the driver, not the strip. The datasheet says “fully dimmable with suitable LED driver”; a dimmer without the right driver achieves nothing.
• Cuttable every 25 mm, wired in parallel.

Colour is chosen once

⛔ This strip does not switch colour. There is a separate part number per colour temperature and our record's colour-changing flag is wrong. Cut and installed, it is the colour you ordered.

• 3000 K — 450 lm/m. Bedheads, living areas, plinths, stair risers.
• 4000 K — 500 lm/m. Bathrooms, laundries, joinery reveals.
• 5000 K — 500 lm/m. Workshops and garages, where a 5 W/m strip is usually a marker rather than a light.

Where it works

• ✅ Shadow-lines, plinths, toe-kicks, stair risers and bedhead reveals.
• ✅ Anywhere the strip is close to the eye — you can look at it comfortably.
• ✅ Long runs from a single small driver.
• ⛔ Not for lighting a work surface — use the 15 W/m.
• ⛔ Not outdoors — ask us for the IP67 version of this same strip.
• ⛔ Not without a 24 V DC constant-voltage driver.

Specifying it

COB true-dotless LED strip, 640 LEDs per metre, 5 W per metre, 24 V DC. Sold per metre. Output 450 lm/m (3000 K), 500 lm/m (4000 K and 5000 K). ⛔ Colour temperature is fixed per part number — it does not switch. CRI ≥90, 180° spread, 50,000 hrs. Cuttable every 25 mm, wired in parallel. ⛔ Requires a 24 V DC constant-voltage LED driver — not included; dimming is done by the driver. IP54 — indoor use only, suitable for indoor wet areas. An IP67 version of this strip exists for exposed positions. ⚠ Maximum run length from one feed is not published — ask us. Warranty 3 years.
