I switched out my old bulbs for these Kor fluorescent ones, and I’m really happy with the change. The brightness is great and the warm light feels way more inviting. Installed easily without any fuss. Would buy again!

One bulb stopped working
I really liked the warm white light from these bulbs until one of them just stopped working after a few weeks. The other is still fine, so I’m debating whether to replace the dead one or switch brands altogether. Kind of disappointed with the longevity.

Not quite what I expected
I thought these bulbs would be brighter based on the specs, but they feel a bit dimmer than my old ones. Still work okay, but I was hoping for more light output. Packaging was also a bit beat up when it arrived. Might look for alternatives next time.

Solid bulbs but delivery was slow
The bulbs themselves are decent. They fit well, and the warm white light is nice. I just wish they had arrived on time. It took an extra week, which was frustrating since I needed them for a project. But they work fine now!
