OUTXPRO 20 Watt Zapper Replacement Bulbs - 2-Pack T8 10 Watt UV Tubes 20 Watt Bug Zappers - 13.78 x 1.02 x 1.02 inch (L x W x H)

The replacement bulbs for my bug zapper never fail me. Whenever a fly or mosquito enters through an opening/closing door, I know it'll be dead before morning. I keep the zapper on 24/7 in an out of the way place and it works like magic.From past experience, I expect to get about two years worth of life from the bulbs, which is fine considering they're always on with the exception of Winter.

It seems there is standard size bulb for bug zappers. Fits the Aspectek version, too. Measures 12 7/8 inches cap to cap (not counting connection prongs). Perfect fit.

The bulbs flickered severely for about a week after I installed them. Fortunately, I remembered that the bug-zapper light did this when it arrived a couple of years ago. Eventually the flickering stops. The bulbs are good replacements.

These little 10 watt lights take so little electricity, but they work great to attract insects in the bug zapper I purchased.

Great Price and bug lamp up and working! Its been on 24/7 for two months with no issues.

The seller was very responsive. I ordered 4 lightbulbs. One was not working. Seller was quick to provide a replacement.

Works perfectly well with our insect lamp. It's not the bulbs that produce the electric shock- it's the zapper. So go for the cheapest bulbs, as long as they provide the needed longevity.

The replacement bulb was a life saver, worked out perfectly
