In January I installed 12 Feit bulbs, mostly in the living room. They are on 12-14 hours a day. Today the one in the lamp beside my chair died. It dimmed, flickered and nearly went out. It is installed base up. When I removed it the base was too hot to handle. The others are mostly in lamps (base down) and do not feel as hot, but are definitely warm.
These are the bulbs that were on sale at HD.
