Review on 🪰 2 Pack Bug Zapper Replacement Light Tube Bulb 10W for 20W Electronic Bug Zapper T8 Fluorescent Bulb Replacement for Bug Zapper by Janet Edwards

None of the 4 bulbs (two of 2 packs) worked in the zapper. They were a lot tighter than I expected but they went into the sockets and I rotated them 90 degrees but none of the bulbs lit up. The flash itself charged (once it shorted me out, and another time I shorted it out first with a screwdriver), but there wasn't even the slightest light, like the original bulbs. The zipper worked when I wasn't using it last winter, except that a lightbulb had burned out. and the second one wasn't that bright so i bought new bulbs here for the start of the fly season. I decided to just buy a new bug trap instead of using these bulbs as there is a slim chance (why I gave it 2 stars and not just 1) that the bulbs prevented good contact because they are so tight fit in my zipper.
