Supposedly with 3 year warranty. 2 out of 6 bulbs failed in less than 1 year. Customer service from Torchstar said i had to send the 2 bulbs back at my expense and then if found defective they would replace the 2 bulbs. I suggested they send me out a replacement 6 pack so if the others failed I wouldn't need to send back individual bulbs. Said not their policy.
