New LED fixture 3w. Green Element EVO Reef LED Light Fixture

[RuGlu6]

yeah same here, i have two ligt fixtures from them:
One is LED for Fresh water cube, it is only 2W for the WHOLE fixture and my FW plants are doing amazing! And color is very good, very happy overall.
Second is 2x250W MH DE +4 T5 actinics +6 blue LED.
And both fixture are of good value.
The only thing with Aquatraders is that they have Ebay like warranty, 30 days only.

The only thing i am still wondering about is what is the difference between aquatraders 3W LED and say CREE or AI sol etc. other then fancy controls?
