The LED tube came packaged very well with me. The light seems at first glance minimal darker than my old 65 watt fluorescent tube, but it is the color temperature fro warmer and more pleasant at 1/3 on power consumption. After 10 minutes you get used to the 5-10% (felt) less light and is excited. The stability is not the same as a glass tube, which can happen that you see a minimal Arch in the led tube, due to the length and the plastic. But this will probably only notice the, who also built the tube.
I'm going to 4 tubes, replace my total 6 in the garage for an extra LED tubes. The two 65 watt fluorescent tubes on the bench, I leave to have at this location a maximum light yield original. If this break down in a few years, I'm going to order me the brightest LED tubes, that I can find.
