Low-voltage strip is the wrong tool for most building outline work, and the reason is not brightness. A 12 V or 24 V strip needs a transformer, and on a facade run of any length it needs power injected every few metres — every injection point is another cable run, another junction box, and another place where water can eventually get in. The installation cost ends up several times the cost of the strip itself, and the failures that appear two years later are almost always at the joints rather than in the LEDs.
Running at mains voltage removes most of that. This strip takes AC 220–240 V directly, so there is no transformer and no low-voltage distribution to design around. The current figure shows why that matters: at 220 V, 5 W per metre draws 0.025 A, where the same 5 W at 12 V would draw roughly 0.42 A — about seventeen times the current, and therefore about seventeen times the resistive loss over the same cable run. That is the entire argument for high-voltage strip on long building perimeters. Note that we do not publish a maximum single-feed run length, because the datasheet does not state one; confirm the feed arrangement against your own layout before ordering.
Be clear about what this model is for. At 400 lumens per metre it is the lowest-output product in the W range — this is a line that draws the eye along an edge, not a source that lights a surface. If you need the outline to do lighting work as well as decorative work, the 780 lm/m 60-LED model or the 900 lm/m models are the right place to look. The 9.5 × 5 mm cross-section is the slimmest square profile in the range, which suits tight reveals. Cutting is at one-metre intervals, so runs are set in whole metres rather than in fine increments. Mounting is by clip and screw, not adhesive. Rated IP65 for sheltered outdoor use — protected against water jets, but not for submersion. Supplied as a 50 m reel with CE, CB, and RoHS certification held by the manufacturer.
