Review on ABI Tuna Blue LED Bulb: Enhancing Coral Reef Health with Optimized Spectrum PAR38 by Ashley Santiago

Got this for my Fluval Sea Evo 13.5. The light spectrum is excellent. The only slight downside is that the light output isn't wide enough, so it misses the frog spawn on the left and the lollipop on the right a bit. Xenia, which is right in the middle and just below the bulb, stopped growing after 2 days. Normally Xenia expands to capture as much light as possible, there is no need to expand this bulb. To solve this problem I ordered another one along with a flexible neck clip. UPDATE - I now have two bulbs and am very happy with them. All corals bloom and grow. Ksenia took root and returned to the fullest. UPDATE 2 - February 14, 2020. One of the bulbs has burned out, the diode has blown. BUMPER! What happens to the lifespan of 50,000 hours? Got another one like 6300. I think I need to order two more.
