"Working great Thank you!" -- Damon Dyche, Ames, Iowa, USA

"These are some mean lights" -- Douglas Norman, Boston, Massachusettes, USA

"I am using your GEM LED bars in my Sumps and they are doing wonders for my Upflow and also my refuge. Interesting, is I made a DIY LED EXTERNAL Panel with 6 Red LEDs and 1 blue, and the GEM LED is doing better, since it's in the water more in the center of the upflow (appears that way). Both in same chamber. in Upflow Scrubber I LOVE IT!!! I may order one more since I have one Spare Power Cord slot. Running two in my other Sump. I will certainly include your GEM LED in ATS as part of the Overall Tank Setup Overview. Will do when Tank Setup is fully completed. Looks like The GEM really Kicked in on New Tank ATS. Good thing, since new setup isn’t growing Algae in DT. GEM is MUMIFIED in growth" -- Wally Brejniak, Canada
