Excellent product that lived up to expectations. 4 of these on the 10ft kitchen lighting ceilings produce a very powerful light. I found that one of my 6 lightbulbs was flickering and needed replacing after a week. I hope other bulbs don't have this problem but I will be buying another pack to fix the broken one and be ready just in case. The price is very good but be aware that if you need all 6 you may have to buy 6 more packs if one of them doesn't work.
