True, and it is. However, if you are going to be using that energy to cool the room anyway, why not try to reclaim that 'spent' energy?

- ISL 13y agoIf you wish to have 1) a cool room at temperature T 2) enough light, L, to see by 3) a happy human at temperature H Assuming that T,H, and L are fixed, you're going to use more energy with a less-efficient process. So, you'll 'spend' more energy to get there. If you're trying to run the process at fixed energy, you're going to wind up accepting a slightly higher T. If that's the case, you'd be able to use even less energy by powering the LED directly and moving the setpoint for T up to that same temperature.
- vidarh 13y agoI think what you are forgetting is that in doing so, you would be heating the room up again. So to keep the temperature where you want it, you'd need to cool the room even more.
- tekromancr 13y agoAhh, you are right.
