I ordered Thanks goodness two LED light bulbs and this mounted in a hallway. Here I noticed that a light bulb is much darker than the second. Complained about the seller and get easily replaced. Many Thanks. If I only get the faulty bulb, me the power loss would possibly not noticed. The LED lamp will start quickly and are pleasant, warm light. A BUY recommendation, if one wants to avoid the sluggish and pollution-rich energy-saving lamps. Admittedly, not very cheap when 25,000 hours life really occur, but a bargain.
