Good bulbs, but it looks like some may be defective. I bought 2 boxes of 2 bulbs each (4 bulbs total). 1 bulb was used in the bedroom and 3 in the living room. After 2 months of use, one of the 3 bulbs in the living room along with the other 2 stopped turning on. If I touch it or move it a little, it starts working. I figured it might be a contact in the bulb itself, so I swapped out two adjacent bulbs and the faulty one turned up within a week. So in my case 1 out of 4 defective light bulbs.
