It lights up the room really well – the light is focused directly down on Ava’s desk, but it’s enough light for the whole room, and it brightens up the walkway outside too.

I don’t have equipment to measure the power spectrum, but subjectively the light appears a little too warm. The new power supply runs the white LEDs at a lower current level than I’d originally planned; I would guess they are putting out about 75% of the planned lumens. It’s not bad – it’s very comfortable, easily the warmest light I’ve ever seen out of a non-incandescent light. If I were going to build another light using the same driver, I’d use a different ratio, but this device will do its job nicely.
