T10 4.0W 225MM (E26 Base)

The light output at 300 lumens is perfect for my desk lamp, and the 4.0W draw makes me feel a bit better about leaving it on all day. It's noticeably cooler to the touch than the old incandescent bulb I replaced.

Swapped out an old 40W bulb in my hallway fixture for this 4W LED and honestly can't tell the difference in brightness. The 300 lumens are spot-on for the space, and it's nice knowing I'm using a fraction of the energy.

I was skeptical a 4W LED could replace the 40W bulb in my reading lamp, but the 300lm output is honestly just as bright. The E26 base screwed right in and it stays cool even after hours of use.
