This LED tube can be considered the brightest LED tube because of its ability to deliver a higher lumen output to serve larger applications and higher energy efficiency than what you get with the other sizes. This LED tube has a 3-4 times longer lifespan than the fluorescent tubes, considering the longest lifespan of any fluorescent tube as 15,000 hours. This LED tube works without a ballast, and hence, the ballast must be bypassed. With an excellent heat dissipation system, this LED tube is designed to work smoothly and for longer.
