Rated 2.0 out of 5.0 by 40W replacement bulb for bug wacker Product arrived on time. Installed the new bulb in the bug wacker but still did not hear any bugs or mosquito getting zap. November 6, 2015
Rated 1.0 out of 5.0 by Fatally Flawed by Design New Stinger UV40, worked first time. But after running all night, bulb would not re-light. Installed replacement bulb. Again, worked first time. Then same thing, wouldn't re-light. Not sure if it's the zapper or the bulb, but as one won't work without the other, the whole thing goes to the scrap heap. Don't throw good money after bad. The UV40 is pure junk. July 21, 2015
Rated 4.0 out of 5.0 by Great replacement bulb This is not a store item, it must be ordered online. The bulb worked flawlessly, turned on instantly when I plugged the bug zapper in. August 26, 2015
Rated 5.0 out of 5.0 by Replacement Blub Replacement blub works as it should. I also own the black light version of this blub. It seem the black light blub attracts bugs a little better in a very dark area. August 11, 2015
Rated 5.0 out of 5.0 by Bug Zapper bulb Thank goodness for these replacement bulbs my mother's Stinger bug killer zaps all night long. Every day or do she blows out hundreds of dead misquitos with a hair dryer. Pick up at Home Depot is wonderful. The light company goes a little overboard on the packaging but they all seem to do that now. July 14, 2015
Rated 2.0 out of 5.0 by Bug zapper It amazes me that manufacturer's and retailers sale a product that doesn't support replacement parts. This has happened on other products too. What happens is you buy the bug lamp and when you need to replace the bulb you have to special order the thing because the store doesn't stock the replacement. I was lucky though, the HD associate at least offered to help look up the replacement bulb and facilitated the order. Your competitor didn't. August 3, 2015
Rated 5.0 out of 5.0 by Stinger bulbs 40 watts They all work good to lure the bugs to the electrocution they deserve. August 25, 2011
Rated 1.0 out of 5.0 by Another store had it cheaper by 10%, same item cheaper Home Depot sold the complete bug light, but now it does not stock the light bulb need for replacement had to order it on the web was not available at the store June 5, 2014
