Unlike fluorescents, some linear LEDs do not need a ballast to power up and produce light. So, a lot of our customers have been asking us about the safety of just bypassing the ballast and direct-wiring their LED tubes.
Several years ago, we saw a lot of problems with this. People were using the wrong sockets. Fires were starting because of mistakes during install. Fluorescent tubes were accidentally post-installed instead of LED tubes, and they were failing immediately when they came into contact with the line voltage running to the sockets.
Back then, we were adamant with our warnings against ballast-bypass linear LED solutions. There were just too many safety hazards for us to recommend this, and the technology wasn't quite there.
