Domus PLEX-SMD 5W P/M Strip 24V CRI90 IP66 70LED/M 1m

The Domus PLEX-SMD-5 is a 24 V SMD LED strip — 5 W per metre, 70 LEDs per metre, CRI ≥90, IP66, 1 m, at 500 / 525 / 550 lm per metre.

⭐⭐ 40 metres on one driver feed — eight times what the COB strip manages at the same wattage

• ⭐ The sheet states “Continuous Run: 40 m Max (one end driver feed) 80 m (two end driver feed)”. ⭐ The PLEX-COB strip at the same 5 W per metre manages 5 m and 10 m.
• ⭐ THAT LOOKS IMPOSSIBLE AT FIRST. ⭐ Both draw 5 W per metre at 24 V — 0.21 A per metre — so the current is identical and the voltage drop per metre should be too.
• ⭐⭐ THE ANSWER IS THE STRIP'S OWN COPPER. ⭐ 70 LEDs per metre leaves far more board width for conductor than 640 does. ⭐ Wider traces mean lower resistance per metre, and the drop is the current times THAT resistance. ⭐ Domus says so in its own words: the PLEX-SMD series “reduces heat and resistance, allowing for extra long runs up to 40M”.
• ⭐ AND THE LOAD IS DEFINITIVELY NOT THE VARIABLE. ⭐ The PLEX-MICRO strip draws LESS current per metre than the PLEX-SMD-9 — 0.333 A against 0.375 — and runs 5 m against 20. ⚠ Higher current, four times the run. ⭐ Run length is a property of the board, not of the load.

⭐⭐ Which sets up the real trade in this catalogue

• ⭐⭐ DOTLESS APPEARANCE AND LONG UNBROKEN RUNS ARE OPPOSED. ⭐ You can have one or the other, and nothing in the catalogue puts the choice in front of you.
• ⭐ SO THE QUESTION TO ASK IS: WILL ANYONE SEE THE STRIP ITSELF?
  • ⭐ If the strip is visible — an exposed cove, a shelf edge at eye level, a bar front — dots matter and PLEX-COB is right, at 5 m per feed.
  • ⭐ If it is concealed and only the washed surface is seen — a ceiling perimeter, a concealed pelmet, a long external soffit — dots are invisible and this strip runs 40 m on one driver.
• ⭐ Behind a good diffuser at any real distance, 70 LEDs per metre reads as a line, not as points. ⭐ The dots show at close range or through a clear lens.

⭐ And it is the more efficient chip

⭐ 500 lm at 3000 K, 525 at 4000, 550 at 5000 — from 5 W. ⭐ That is 100 to 110 lumens per watt, against the COB strip's 90 to 100 at the same wattage. ⭐ Discrete SMD packages shed heat better than a dense COB array, and cooler LEDs are more efficient LEDs. ⭐ So the long-run strip is also the cheaper one to run — ⭐ the appearance is the only thing you give up.

⭐ IP66 — the rating that goes outside

⭐ IP66 is a different proposition from the IP54 and IP67 elsewhere in the range. ⭐ Domus describes it as “indoor or outdoor weatherproof” — ⭐ the 6 for dust means fully sealed, and the 6 for water means powerful jets, which covers driving rain and hosing. ⚠ What IP66 does not cover is immersion; IP67 does. ⭐ For an external soffit, a fence line or a long garden run, IP66 at 40 metres is the combination that makes this strip unusual.

⛔⛔ It still must be mounted on an aluminium heat sink

⭐ The sheet states it in capitals and voids the warranty without it. ⚠ At forty metres that is forty metres of profile, ⭐ and on an outdoor run the profile has to suit the exposure too. ⛔ No description says any of this and none of the catalogue's 47 profiles names this strip. ⭐ Ask us to quote both.

Where it works

• ⭐⭐ Long concealed runs — ⭐ 40 m on one driver.
• ⭐ External soffits, fence lines, garden runs — ⭐ IP66.
• ⭐ Ceiling perimeters and concealed pelmets.
• ⛔ Not where the strip is visible — ⚠ 70 LEDs/m shows dots.
• ⚠ Not where lengths must land finely — ⭐ 100 mm steps.

Specifying it

SMD LED strip, IP66, 1 m. 5 W per metre at 24 V DC. 500 lm at 3000 K, 525 at 4000 K, 550 at 5000 K. 70 LEDs per metre. CRI ≥90. 120° beam. 100 mm cutting increment. Continuous run 40 m one-end feed, 80 m two-end. −20 to +50 °C. Aluminium heat sink mandatory. 3-year warranty. ⭐⭐ IT RUNS 40 METRES ON ONE DRIVER FEED WHERE THE COB STRIP AT THE SAME 5 W PER METRE MANAGES 5 — and both draw an identical 0.21 A per metre, so the load cannot be the reason. THE VARIABLE IS THE STRIP'S OWN COPPER: 70 LEDs per metre leaves far more board width for conductor than 640 does, and Domus says so directly ("reduces heat and resistance"). ⭐ THE TRADE NOTHING STATES: dotless appearance and long unbroken runs are opposed. Ask whether anyone will see the strip itself — if not, this is the right product.
