I'm building my home lights with an SMD5050 Led strips. And I'm completely lost after comparing specs consumptions with real measured data.
So on, I have 5 stripes and 1-to-5 Splitter from my controller: 2 legs for 10m each, both sides fed from the splitter. 5th one is single-feed from a same 1-to-5 splitter. So, that's properly builded scheme and I don't expect
In total: 10m 30Leds/m for 7.2W/m and 15m 60Leds/m with a 14.4W/m. Oh yes, that's should be 288W and 20A x 14.4V!
I have a Wattmeter, that stands before 220V input of my 15A 12V Led power supply, and I can measure only 90W of consumption in the HARDEST case, which I mean 14.4V output of supply and White permanent color on strips. That's 3 times less than proposed to be (don't counting imperfection of 220-12V transformation).
Why so? Does it mean that I can connect more and more strips, and the power supply will handle it? (Specs for supply is 180W max consumption, so currently it's loaded just 50%).
How to figure out, where the real consumption is? I don't have a reason to untrust my Wattmeter - used it with everything in my home from phone chargers (4W) till AC (800-1200W), and collected data seemed very real..
