I have had the Flowtron BK-80D every sence the first of last summer 2014 and have now had to replace both bulbs. The first one went out about 2 months after purchase. The second about a week ago 7/ 2015. The BF-150 Bulb I order this year would not push into the socket for the four prongs were two large. So I sanded the prongs down and the bulb would fit. I also noticed that for my BK-80D that when I first bought it last year the tops of the bulbs would would not light up blue just orange. So I turned the bulbs around and put them in and they both lit up solid blue. No where does it say the bulbs has to be a certain direction, but mine do are they will not light up totally blue. The name Flowtron made in China has to be facing inward toward each other. Am I the only one with this problem or is it just my Flowtron? The other problem is mine does not draw mosquitoes. I had a Flowtrom about 15 years ago and you could hear and see the Flowtron drawing mosquitoes all night long. Also you could not get close to the older Flowtron because it was surrounded by mosquitoes. Thats why I bought a Flowtron again but this new one does not draw mosquitoes. I don't know if we have a new breed of mosquitoes that are not drawn by the Bug Light or the newer Flowtron does not work like the older one I had. I also have a half an acre Flowtron BK-15D and this one does not draw mosquitoes either. Mosquitoes seem to laugh at both. Ha, Ha!
