### ⭐ Purchased lots of t5 in 20 years and these suck
*by P***E on January 1, 2026*

Just do yourself a favor and don't make price your biggest concern. These bulbs drop in brightness within the first 6 months and then they start burning out like crazy. I purchased a package of these in February and have used them 18 hours a day until January 2027 so about 10 months. The brightness had dropped by almost half at the 6-month mark as measured with a light meter. only one of them are still working In January 26th. They burn out prematurely as normal t5 fluorescents last several years out of the box. They sell a lot of them apparently because they show up at the top of the search results and they have a competitive price. Unfortunately they suck and I've been buying these type bulbs for over 20 years.
