Review on 💡 High-Efficiency F4T5 Fluorescent Tube with Low Mercury Content by Wanda Johns

I can't rate this article yet. I installed them easily enough, but they didn't catch fire. I just put new batteries in and checked to make sure they are in the right place. It's a Coleman lantern. The tubes I removed were clearly burned out. I bought a used flashlight so I don't know if it's the tubes not working or something is wrong with the flashlight. I don't know what to do next. ?
