These bulbs are an excellent replacement for the super hot energy-guzzling halogen bulbs i had. Work perfectly with my dimmers and have amazing light.

These are might whiter and very narrow. Inspite of the title saying they are dimmable, in the questions, it says it is not dimmable.

They have good brightness and color. They are bright and haven't dimmed since i installed them. It is brighter and my electric bill is lower.

Buy these lights. Well packaged. My only complaint with my recent purchase is the packaging.

Three of the six bulbs flicker after they are on for about 20 minutes so half of them are defective. They are rated at 20,000 hours. Two bulbs were burned out within 18 months. Total usage not even close to 2,000 years before bulb failed.
