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.

Easy to install, no delay in start up, the bulb comes on with no flickering. Nicer to have the bulb in an overhead fluorescent fixture than as an lamp on a desk. My birbs are happier now and their feathers have perked up again.
