I bought 4 x 15 of these equivalent 11w LED bulbs to replace glass incandescent bulbs in street lamps. I had to replace 48 lightbulbs. I only used them for one night but first impressions are really good. Based on previous experience with relatively cheap LED bulbs, I expected at least a few bulbs to fail immediately. I was pleasantly surprised that 48 of the 48 bulbs installed worked. The plastic body is transparent enough that it's hard to tell from a few feet away that it's not glass, but a quick test from about waist height on concrete confirms they don't break easily (unlike the glass bulbs ). came with my garlands) that break if you sneeze on them - not good if they walk across my patio and pool). The only reason I removed the star is that the quality control seems a bit lacking. While all 48 lamps lit up in sequence, two had their filaments bent so much that they almost touched the plastic housing. They still work and can't be said for sure from across the yard, but it bothered me enough that I swapped them out and kept them as spares. To be honest I would only deduct 1/2 star for this if I could but I can't and I don't think they deserve a perfect 5 star for that one reason alone. Overall, for the price, I highly recommend these pears. . Just buy a few extra if you think the visual imperfections will bother you like they did mine.
