> Strangely the thing that I really noticed when we stopped using incandescent bulbs was that it felt a lot colder during winter nights, as the majority of the energy the old bulbs drew was converted to heat rather than light. I swap in incandescent builds into a certain cold room in the winter, to deliberately exploit that effect, then I swap them out for LEDs during the summer. IIRC, it wasn't uncommon to use incandescent builds as cheap heating elements. IIRC, early in the push to ban incandescent bulbs, some German tried to sell them as "heat bulbs," but got squashed by the regulators. A side effect is really just an effect, and they can be useful. In the race to totally ban things, that often gets lost.
