My BK-40 stopped working after 11 months. I thought it was a lightbulb so I checked and it had a black spot in it so that was bad. This bulb came, I changed it and it still didn't work. Then I looked at the starter bulb in the block and that was bad too. I ordered a starter lamp from Flowtron and it arrived. Installing the new starter bulb was very easy. Connected and it works with errors! Now I'll have a timer on a timer, so maybe it will take longer. Before that, it was active 24/7 for 11 consecutive months. My mistakes were fewer last summer it seems. I do not believe in the information on the Internet that they do not work in the fight against bugs. There are always tons of dead bugs. I clean it by blowing on it with a blower and it cleans in seconds.
