WebMay 10, 2005 · However, crucially, heat is produced within the LED device itself, due to the inefficiency of the semiconductor processes that generate light. The wall-plug efficiency (optical power out divided by electrical power in) of LED packages is typically in the region of 5-40%, meaning that somewhere between 60 and 95% of the input power is lost as heat. WebThe answer is the Basal metabolic rate which is, as it turns out, ~60 Watts. So, a human will heat up a room roughly the same as 1 60 W light bulb would heat up a room. (Though, the light bulb would actually heat up the wires and heat locally, more, while humans would heat the entire room a bit more). Still, they are about the same.
