Note: 1, LED Bulb that can not cover the combustible. Install LED Bulb need to tighten the fixture or lamp holder. 3, installation and replacement LED Bulb must cut off the power, to ensure personal safety. LED Bulb Ambient temperature -20 ~ 45 ℃, Storage ambient temperature -40 to 80 ° C. Rated voltage AC85V-265V (MR16 by is AC/DC12V) 50-60Hz. Long-term use, the voltage is too high or too low will affect the normal use of the function and life. The contact performance LED Bulb exception (self-extinguishing, flashing), check the fixtures and the supply voltage is normal, are normal fault persists, the need to exchange the new lights.
