5-Pack of ZHONGQIAN ET1200 T8 LED Shop Light Tubes - 4ft, 20W (40W equivalent), 5000K (Daylight Glow), Single-Ended Power, Frosted Cover, G13 Lighting Fixtures, ETL-Listed

Bright and decent price for 6 tubes but these Zhongshan ET1200 T8 LED tubes are definitely not dimmable, at least not to a useful degree (maybe 90% to 100% dimmable). The Technical Details in the description state incorrectly that these are dimmable. I tested them with direct AC connection (no ballast) and they started strobing very badly below 90% dimming.

Labeled wrong . Needed double ended led lights was shipped 19 boxes of single ended led lights.This is after making sure that the lights I wanted was the lights that would be shipped. Nope ! If you need double ended led lights you will be shipped single ended power lights.Thanks for wasteing my time . Please check out the misinformation on your listing.

Really bright! Loved the difference between these and the old fluorescents.

Cover is not clear per the description it is a milky white cover can not use for my application. Had to return. Model # in description is Zhongqian ET1200 on the boxes I received Zhongqian ZQ-ET1200. It may be the wrong item was picked for my order.

Can't believe how much light these put out. Excellent deal and great item.
