Domus PLEX-COB-5-IP67 - 5W LED Per Metre 640LED True Dotless Striplight IP67 24V - DRIVER REQUIRED

The Domus PLEX-COB-5-IP67 is a 24 V DC COB LED strip — 5 W per metre, 640 LEDs per metre, CRI ≥90, IP67, sold per metre in 3000, 4000 or 5000 K.

⛔⛔ Its voltage field says 240 V. It is a 24 V product.

• ⭐ This listing publishes voltage = 240 V. ⛔ Everything else about the product says 24 V: ⭐ the title, the output_voltage field on the same record, the datasheet's “24V DC Per Metre”, and the requirement for a “24V DC Constant Voltage LED Driver”.
• ⭐ Measured: five strip products in the catalogue publish 240 V, and every one of them is a 24 V DC product. ⭐ So it is a small, specific, fixable set — not a convention.
• ⛔ THIS IS THE WORST DIRECTION FOR THE ERROR TO RUN. ⭐ A mains product labelled 24 V would simply not work. ⚠ A 24 V product labelled 240 V invites someone to connect it to mains, which destroys it instantly and is not safe.
• ⭐ TO BE UNAMBIGUOUS: this strip runs on 24 V DC and requires a 24 V DC constant-voltage driver. It must never be connected to mains.

⛔⛔ And it must be on an aluminium heat sink or the warranty is void

⭐ The datasheet states it in capitals — “All LED strip must be installed on an aluminium heat sink, failure to do so WILL VOID WARRANTY” — ⭐ and seventeen strip sheets in the range repeat it. ⛔ No description says it and none of the catalogue's 47 aluminium profiles mentions PLEX-COB. ⭐ Budget a profile with every metre; it is the heat sink the warranty depends on, not a finishing touch.

⭐⭐ Choosing IP67 costs 15% of the light — measured

• ⭐ The IP54 and IP67 sheets publish per-metre lumens for the same wattages, so the coating's cost is measurable:

• ⭐⭐ AND IT HOLDS AT EVERY WATTAGE. ⭐ Across twelve comparable pairs spanning 5, 10, 15 and 20 W, the loss is −15.6% at 3000 K and −15.0% at 4000 and 5000 K, every time. ⭐ A range that tight is a real optical loss in the silicon, not measurement noise.
• ⛔ Nothing in the catalogue states that choosing IP67 costs light. ⭐ The two versions are presented as the same product with a different rating.
• ⭐ THE PRACTICAL POINT: do not over-specify IP67. ⭐ It costs 15% of the output, it makes every cut a breach of the seal, and IP54 already covers “indoor including wet areas”. ⭐ Take IP67 for hosing, standing water or genuinely outdoor positions — not for a bathroom.

⭐ Sold per metre — the format that suits a heat-sink budget

⭐ Buying by the metre lets the strip length match the profile length, ⭐ which matters more here than on most products, because the profile is mandatory. ⭐ Order both to the same measured run and the 25 mm cutting increment gives you a tolerance of about an inch. ⚠ Note the increment: you can only cut every 25 mm, so a run must round to that.

✅ What is published

Where it works

• ⭐ Wet-area runs cut to a measured length.
• ⭐ Matching strip to profile metre for metre.
• Hosing, standing water, outdoor positions.
• ⛔ NEVER on mains — ⚠ despite the voltage field.
• ⚠ Not for a bathroom — ⭐ IP54 costs 15% less light.

Specifying it

COB LED strip, IP67 silicon coated, per metre. 5 W per metre at 24 V DC. 380 lm at 3000 K, 425 lm at 4000 and 5000 K. 640 LEDs per metre, dotless. CRI ≥90. 180° beam. 25 mm cutting increment. Continuous run 5 m one-end, 10 m two-end. Dimmable with a suitable driver. 3-year warranty. ⛔⛔ ITS VOLTAGE FIELD PUBLISHES 240 V ON A 24 V DC PRODUCT — the title, the output_voltage field on the same record and the datasheet all say 24 V. FIVE strips in the catalogue carry this error and every one is a 24 V product. IT MUST NEVER BE CONNECTED TO MAINS. ⛔ AND IT MUST BE MOUNTED ON AN ALUMINIUM HEAT SINK OR THE WARRANTY IS VOID. ⭐ Choosing IP67 also costs 15% of the light, measured across twelve pairs — so do not over-specify it.
