## Questions & Answers

**Q: My Flowtron originally came with a bulb labeled BF35-8131, is this the correct bulb replacement?**
A: I might of had the same issue of not knowing when I bought it. So what I did was I checked the number of BF-35 and then I looked at the prongs and checked if it was the same as the original. It fit perfect and worked well. Not a very scientific way to check but hope it helps.

**Q: does the bulb need to be replaced on an interval, or only when it burns out?**
A: My zapper and bulb worked until it would not light up.  I just replaced the bulb which has lasted for over 3 years.  The previous one lasted over 4-5 years.   I only use it during the late spring to early fall.

**Q: The product information box says this is an led. is that true or is it really cfl with a mistaken entry on the page?**
A: its not a true led it's replacement bulb for the bug zapper

**Q: Will this bulb fit my severino zap t6 pro bug zapper?  bulb: ful15w-bl (1.78"l x 0.96" w x 7.75" h) i do not know the 4 prongs insert size. thank you.**
A: YES
