LED strip, a little discovery

Last Friday I received my first roll of LED strip. 5 metres of warm white 5050 LEDs, out of which I need only 1.10 m. When preparing my strip for deployment I noticed that it is not made of single, long, uninterrupted material: it is a sum of 1 m long sections.

At 12 Vdc the strip is pretty bright and does produce a decent amount of heat. No wonder people complain these LEDs loose luminosity! Heatsink is required for a long LED life.

Since I do not need that much light I reduced the supply voltage to 10.0 V and the result is still too much for night work.at the laptop.
