I have searched the forum about this subject and cannot find anything newer that about a year ago on the subject. There have been some recent threads about the 4' 2 bulb shop lights from Sam's and Costco, but nothing recent about replacing the bulbs in existing fixtures with LEDs. I have a total 16 4 bulb t8 fixtures in my shop that I installed over 10 yeas ago when I built my shop. Mostly these are still in good working order and I have only replaced a few of the bulbs and the ballasts in one of the fixtures. I currently have a fixture that I believe the ballasts is going out on. After replacing the bulbs it still flickers and sometimes I have to turn the switch on and off and then back on a few times to get it to come on. These fixtures have 2 ballasts and replacing the ballasts will cost $30-40 to replace both, so I have been looking at this as an alternative.
Does anyone have any experience with this particular bulb or possibly other alternatives? Cost is very important to me and these are pretty much at the top of my budget. So if the recommendation is that LED's in this price range are crap, then I will just go the route of replacing the ballasts and keep the t8's.
