I run all my fluorescent tubes straight-wire -Replaced LED bulbs which are so superior to the old fluorescent tubes. Everything was going smoothly until I changed this size. I put them in and blew them out immediately. When I realized why they need ballast to work. Why the heck should I change them if they need ballast?I wrote down the correct straight wire bulbs.Not happy with them but the details say they need ballast so I'm giving it three stars instead of zero.
