Review on 🐜 SleekLighting 13W Spiral CFL Black Bug Light Bulb - UL Approved, 120V, E26 Medium Base - Pack of 2 by Marcus Price

They work well but be aware that one of them is NOT "bright" enough to make a big impact in a large room or even a long hallway. The effect is so local that even with the lights off in the rest of the apartment, my shirt only glowed when I was standing directly in front of the light. in the hallway If you can fit a couple of these bulbs in or put them in a multi-bulb lamp, they might work better. Because I don't need them and I can't return them.
