What do you see from these photos? These photos were taken by the famous Chingchai Uekrongtham from Thailand who has a world-wide well-known saltwater reef tank. This tank was lit up with metal halide lamps as the main light source with the support of some VHO tubes for actinic improvement. We feel very honored that Mr. Chingchai decided to replace all his VHO with our COB series SuperActinic units. Before he made this decision, he spent much time on studying the product specification and he even measured the PAR and spectrum that our COB units can provide. We are so happy that Mr. Chingchai was eventually convinced with the results measured. He is now having 10x CB-120SA units on this tank. According to him, the tank now looks quite nice under these lights.
