I really like this lantern. I've had it for 2 months now and have no problems. My plants grow fantastic and there are no algae problems when I work 10-12 hours a day. I don't use blue light as I don't feel my fish can sleep that well. I recently bought a Hygger backlight and there is NO comparison so I bought another one to replace. You will see the difference in the photos posted. The clearer, the brighter the light of this mark.
