This LED tube can be considered as 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 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.
