Normally when people complain of led bulbs being slow to turn on, it's actually the dimmer at fault. Most dimmer switches have only two wires, and so charge their caps through the bulb. Since LEDs draw far less current, this takes longer, and so the bulb takes longer to appear on.
- danielweber 10y agoI have some stairways I must light up and they need to light up instantly for safety reasons. I make sure one of the bulbs in the fixture is incandescent, and CFL/LED the rest.
- tempestn 10y agoYou can also not use a dimmer, or use a (quality) dimmer intended for LED bulbs. (Many dimmers supposedly for LEDs will still not turn on instantly.)
- danielweber 10y agoI have no dimmers at all in my house.
- tempestn 10y agoBizarre that the LEDs would have a delay then, or that including an incandescent would make any difference in that delay. (Or are you saying it doesn't make a difference in how quickly the leds turn on, but it itself turns on faster? I guess if they're cheap ones with poorly tuned internal rectifiers that could be the case.)
