LED experience for under $2

I agree that the blue/white flicker is kinda annoying , but being able to fine tune your color temp by dimming the different color LEDs is a huge plus . Next tank i light will be with a diy led setup , probably from rapid led . Now i just have to hurry up and get a new tank .

MHs are certainly not outdated, still by far my personal favourite for color and effect. LEDs can't offer the effect from the single source which creates stunning rays and shadows for contrast. By far the most natural lighting and the best lighting for photography is MH. Also for actinic effect fluorescents take that prize not LEDs.
