These are cheap garbage. Within the first month 2 bulbs burnt out. Now barely 3 months and 5 bulbs have burnt out. Whats weird is that the bulb is actually not truly burning out, inside is still in tact, rather the metal conductor on the end of the bulb just stops conducting, because at first you can wiggle the bulb and it will come back on for a few min, then go out again. After a couple wiggles the bulb no longer turns back on. They also included 5 spare bulbs which I used up already. Not worth the money at all.
