Hannah I. ★★★★★ Oct 13, 2026

These little T4 bulbs fit my chandelier sockets perfectly and the 4.5W draw barely registers compared to the 50w ones I had in there. Light output is right around what the old incandescents gave me, just slightly cooler.

Ruby R. ★★★★★ Oct 12, 2026

Swapped out the old 50w incandescent in my dining fixture and honestly can't tell the difference in brightness, which shocked me. The E12 base screwed right in with no issues and it runs way cooler too.

I was surprised how well this tiny bulb matches the brightness of my old 50W incandescent, and it uses a fraction of the power. Perfect fit for my chandelier's E12 socket.
