This i third time I purchase this COB LED chips for my converted light. I found that the life is shorter and shorter than the first time although I and a 4X5 inches big heatsink with small fan for cooling. The first time purchased last for about one year with about 15 hours each day. It is about 5400 hours only and is a bit short already, but later purchase are even worst. I doubt is it quality issue. Anyway, still better than using halogen bulb. I will try to source better one.
