Review on 💡 Optimized Replacement Bulb for Flowtron BK-40D - Flowtron BF-190 by Justin Herman

Exactly the same as in my original zapper. I don't understand why some of them are different color? My light stopped working and I wasn't sure if that meant the unit was broken too. But I received the bulb thinking I could try it and if it didn't work just send it back. - Came wrapped in bubble wrap so it was well protected. - Easy to install in an existing bracket. I had to give it one last push to get it all the way down, but it was easy. All in all, this is a great replacement. I hope it works for a few more years.
