Do LED bulbs get hot?

Compared with LED bulbs and phosphor energy-saving bulbs of the same wattage, which bulb generates more heat when in use?

From the perspective of energy conversion, as long as 100% conversion is not possible, heat loss will inevitably occur, and LED lights are no exception.

Energy saving lamps use DAO electronic rectifiers. Compared with LED lamps, LED lamps have higher luminous efficiency, save electricity and produce less heat.

Although LED lights produce relatively little heat, they still generate heat. Especially since LED lights are point light sources, the heat source is more concentrated and the heat sinks must be matched to dissipate the heat.

When you say 2U3W CFLs, 2U refers to the number of lamps, two lamps combined into a whole.
