Extra bright CFL. The lamp consumes about 37 watts after warming up. I am using the first one I bought over a year ago in my bathroom and it works just as well now as it did the day I installed it in my faucet. Note that most light fixture covers will not fit over the bulb, they are twice the size of regular 23 watt CFLs. UPDATE 3/3/2020: They last about a year with continuous use 12-16 hours a day and about a year. one and a half in the bathroom, where it turns off and on several times a day (I have two working at the same time, and there is always a spare). I'm lucky I don't have to replace my lights with 200w bulbs to use incandescent bulbs and I can see even with my very poor eyesight which is worse in moderate light or darkness. The savings on my energy bills are a bonus, together two of these lightbulbs I use can save $40-$50 a year - not a big deal but it's extra money in my bank account. В 2005 году, когда я заменил все свои лампы накаливания на КЛЛ (100-ваттные лампы накаливания на 23-ваттные КЛЛ, за исключением моего офиса и ванной, где я заменил их более яркими КЛЛ), мой счет за электроэнергию уменьшился примерно на 10 долларов in the month. Some have been replaced with LED bulbs, but the difference in wattage is so small that I haven't noticed any other changes on my electricity bill.
