2 par38's @ 20k w/ 60 degree optics by nanotuners over a 12 gal nano roughly 18x17x15.
Pro's- Electricity cost reduction, longer lifespan tbd, long term cost savings due to bulb replacement vs mh/t5, plug and play for this paricular product
Con's- Spot light effect and shadows, no long term evidence of suitability for corals, foresee evolution of technology will outdate current components, like better and faster computers. Added an additional spotlight for more coverage and viewing appeal.
Just purchased a diy retrokit from rapidled and will put this in my old nano hood. Going to use the spotlights for a qt, frag or specific coral tank. I got 12 led kit with a constant current driver 6 blue and 6 white @ 3 watts each. This should arrive next week.
I am seeking a cleaner nano look instead hanging par38s and the experience with this diy. Lastly and hoping that this will have bettr spread without spoltlight effect.
Hope this helps.
