Tonight I changed out about 20 or so EoL or near EoL F32T8s. Most were GEs from 2018-2023 that with no surprise, did not last very long. Had a few older Sylvanias (2001-2010 ish vintage and a few Philips from 2018-2024 vintage as well. (Changed out a few Sylvanias at another building that didn't make it 5 years as well. Stupid transition over to Chinese manufacturing

The newer ones were all the 900 series. The old ones were the 700/800 series.
