Got 6 of C90, very good production quality, aluminium case, nice even rows of led's, light and sleek.
Light is pretty narrowes through the lens of the LEDs so it penetrates through water very good, best results when you combine several units to light up aquarium. Lacks a bit of blue but thats just my opinion and taste.
Im very satisfied, esp. with the electricity bill LOL

excellent item it arrived in contact with out any damage and arrived fast from hongkong to the uk. you can track the item all the way from hongkong rite to your door. buy buy you wont be dissapointed

excellent light unit. nice design it looks stunning over my tank reccommend to any one. they give off good light, i have two units on my 3x2x2 reef tank. the two units give off the same light output as my 150watt halide.

Ones my the lamp was placed,in a short time,all my polys corals and Rhodactis opened up..This leds lamp are 14.000K and give a special spotlight effect very alike to Metal Haide.
