到了就碎了一个

They fit perfectly, I ordered them for my grandfather and he wasn't mad. They were also a great price.

I have 5 banks of 4 high intensity Sylvania fluorescents, installed in 2001 (yes!). A few bulbs were beginning to fail last year (2025) – pretty good life expectancy. Thinking it might be a good idea to replace all at once, these Konideke seemed like a good economical choice, and they all worked well for a while with good brightness and light quality. They turn out to be a load of rubbish. Half a dozen have failed completely after only 6 months, and several others are on the blink with darkened ends, low intensity and off color. No warranty, what should I have expected?

I bought these for my bug zapper. But the bulb didn’t fix it. So unfortunately I haven’t used yet but they do seem to be a quality bulb

After searching locally I couldn’t find this replacement bulb anywhere, this is a perfect replacement for the burned out bulb in my bug light. It works just like the original bulb.

This bulb correctly fit the Black Flag Bug Zapper that I put it in. I ordered my bulb in June 23, 2024 and used the lamp consistently until it went out on Jan 8, 2025. I got about 6 months or 4380hr (182 days) instead of the "6000 hr (365 days) of life" claimed. Roughly half the claimed time. The factory bulb lasted several years.

Me llegó el 4 de Novienbre y lo instale trabajando bien. Y para el 8 de enero ya no funcionó. Prácticamente duró 2 meses, donde el original me duró 4 años. Instale uno nuevo 6 de mayo 2024 y espero y dure más tiempo.

My bug light bulb had burnt out. The exact part number that was printed on the old bulb was not listed in Amazon but this was suggested as a replacement. It fit perfectly and has been working now for a few weeks. No complaints on this purchase. It was also much less expensive to replace the bulb rather than buy another new bug light.

It only lasts 16 months so have buy a new one again

Sorry, the bulb didn’t work as expected.
