not enough information on stated goals.. i.e Heavily planted, high tech w/ CO2 ect..

Other than that any LED's would need narrow optics i.e 60 degree lenses..
2 strings of 12 to 15 should do it.. one "blue tones" one "red tones" w/ dimmer for each channel..

Thanks for this, I thought it would be too boring to read all of that......


It is a heavily planted tank, with pressurized injected CO2. I already have reflowed 5 blue and 2 red leds separately. I do EI dosing with additional Ferrous sulphate with weekly 50% water change.

The substrate is ADA Amazonia, with another end having river sand. The baby tears, Hair grass carpet is on the ADA and Giant mint, swords, Riccia, Java fern, dwarf microsorum Pteropus, Lagenandra ovata green-Araceae, Tropical Hornwort, Dwarf Sagittaria, AP Hygrophila polysperma, Rotala wallichii, Ammannia Red senegalensis,
11.Ludvigia perennis-water form-new ludvigia, Myriophyllum scabraium, myriophyllum tuberculaium red, Nymphaea sp Leopard red Lilly, Tropical Night blooming Waterlily, Hemianthus Callitrichoides 'Cuba', Glossostigma elatinodes.

Would request if I can get the number of the LED chip (15x2 strings) to buy or the specs like Kelvin CCT, Watts per LED and Lux etc, I could reflow those and remove my two CFL 38 watts each.

Thanks in advance

2 rows of 8-9 3W LEDs.
60-90 degree optics..depends a lot on height from tank substrate bottom.

Could anyone please guide me where I can buy 3 watts LEDs reflown on PCB stars having 10000 plus CCT Kelvins, here in Mumbai.
