- CAUTION: ALL 120 AND 240 VAC BULBS ARE FOR USE WITH STANDARD ON/OFF SWITCHES ONLY (unless specified as dimmable). Use with any type of dimmer, relay or other control circuit will VOID WARRANTY. LEDs are very sensitive and subject to premature failure from electrical noise spikes
- Excessive heat will cause LEDs to fail prematurely. They must be operated in an ambient temperature, not exceeding room temperature, for maximum life time. As the temperature rises above 23 degrees C, the life time goes down. Active cooling, such as a small fan, may be required if they are installed in a small enclosed space without ventilation.
