I have a 12V socket that has two tiny LEDs in it. But they stay on as long as they have power (so you can find the empty socket in the dark -- and it looks kool.) So asked myself, how important is it to have a switch for those lights?
To contrast, the computer I am typing this on uses 292W average with two monitors. So, I can get about 4 hours with an 1150w battery (ignoring inefficiencies and 100% DoD).
The LED lights came in at 34 mA @ 12V. That sounds small, right? 0.034 * 12 = 0.408 watts. Not even half a watt!
9.792 WH / day, or 297 WH per month. Leaving them running for 1 month consumes 1 hour of computer usage. It will take less than 4 months to kill one 1150w battery. It can kill 3+ of those batteries in a year.
This is why Google shows it's cloud prices by the hour.
