Very small but arguably 10x-100x more numerous, so it's not negligible. Especially once you start accounting for the spread of LED lighting.

- nabla9 3y agoNot negligible, but small. Lighting is roughly 9 percent of home electricity usage, TV and Media Equipment: 4 percent.
- amluto 3y agoLED lighting almost invariably wants constant current DC, so there’s a conversion stage regardless. The only major sort-of exception is LED tape, which uses a constant voltage supply, but internally, and lossily, regulates current. A modern high-quality LED light bulb uses a little IC that controls a non-isolated switching converter. You can find excellent datasheets online.
