They are led and adequately large, as visualized. The lighting power is not as bright as i thought they would be, but still enough.

This bulb performs its functions perfectly. The dusk to dawn feature is awesome! It works great. The motion sensor works very well.

Sturdy, well made light bulbs. Longevity is unknown at this time, as someone with a degree in electronics i can say that these things are - ahem - brilliant.

The brightness is decent for illuminating a porch, and the yellow does seem to diminish the bug volume. Any ambience from color is to mitigate attracting flying insects. Thebrightness is good and not to dim.
