I just put up my lights that I purchased nearly one year ago - at the time I opted to go for the more expensive C9 LED SMD dimmable bulbs. They are quite stunning...all 250 of them! However, this year after I put them up, I noticed three that were not operating. Okay, I thought...I must not have screwed them in enough. Well, it turns out that they are burnt out. I understand that LED, like any bulb, has a lifespan, but I expected more than one season from them. I've called Christmas Light Source to see if they'll replace them for me...got a quick call back and no problem, they'll send me 3 replacements! Now that's first class customer service...which is why I recommend them wherever and whenever I can!
Great pure white bulb no issues
