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.
These bulbs were purchased primarily for their advertised longevity. The price is also, better than lowes. Love the economical factor a lot. My only real concern is with longevity.
The color of the light is pleasing. Warm looking with plenty of brightness without being harsh. Light is clean & bright.
The luminosity levels on these are better than the 3-way incandescent bulbs i replaced. No flicker and relatively good color rendering for the price point. As a 3 way lighting is very good with level control.
It's less than a week old.
