My computer.
1% go into light, the rest of it warms up my surroundings.

>> No.3825286

Anything intended to give off heat should be 100% efficient, given that in this case energy lost as heat isn't an issue.

>> No.3825290

>>3825271
All energy eventually goes to heat, which is the heaters purpose.

>> No.3825292

>>3825271
Light which turns into heat after it hits something.

>> No.3826205

A power switch. 100% effective!
