Incandescent bulbs are good to use at night (but not for daytime). Low blue and green light. They have flickering at 100Hz or 120Hz depending on where you live, but the curve for the PWM is sinusoidal because the fragment has a certain thermal retention that produces an attenuation.
I don’t use them because:
- They still have some blue and green, which I’d prefer to avoid completely.
- They heat up my room, which is already hot (I live in Spain).
- They increase the electricity bill pretty bad, and won’t last much (usually ~2000h or less). However, you could connect a thermistor to the lamp in order to make the incandescent bulbs last longer.
