The uv LED cost 35 bucks from oznium.com.
The ecopico arm was 115.00 total with the arm, the strips, the expansion and the ac adapter.
The ecopico seems bright enough, my only concern is if its going to be enough light to grow ug and erios. Seems like im getting mixed opinions on that. I cant seem to find anyone that has actually used one for any extended period of time while growing aquatic plants. Guess ill be the guinea pig.
As for the disco effect, it actually wasnt intended to be that way. My son wanted to make it look like "stars" at night, but the blue flourescent pen kinda took that over the edge. The background will probably make its way into the trash as soon as he forgets its there...lol
