LED Lighting

[steven847]

Hello Guys,

I'm new to this forum! Been reading some of the interesting threads that have been advertised on Facebook and I thought that I would join! So here is my first thread.

I've been in the hobby for just over a year now. Upgraded my tank 3 times now! I decided to purchase a 90 gallon aquarium, however, it had a twin T8 fixture. I really wanted to start keeping hard corals and I knew that this wouldn't do. I've replaced it with an LED fixture. The fixture contains 48 LED's: 16 x white (14,000-18000K), soft white (6500K), 16 x blue (450-460nm), 4 x moonlight blue (460-470nm) and 4 x violet (120-430nm). Each channel is fully programmable (violet and soft white are on the same channel). The lighting looks quite purple in colour. Would anyone have any advice on what ratio I should have the lights on please? The lighting unit has day and night cycles with 9 different light settings in each cycle. I'm under the understanding that the ratio should be 1:2 for white:blue is that correct or just personal preference? Also should I just turn off the violet LEDs?

Any advice would be greatly appreciated

Thanks,

Steve

Thanks for getting back to me. The fixture is a Chinese build LT LED LT SL-A008-90. The link to the site I bought it from is here LT SL-A008-90 Dimmable Marine LED Aquarium lighting system I don't think it's a well known brand.

I really doubt there is a single chip LED White 14-18K. Many Imports rate their Cool Whites above 10K only because nobody calls them on it.

The 420-480nm is your primary grow for corals.

That said I would tune the lights to the look you like, then back them off for acclimation as LEDs are brighter than advertised.

Given your description you may have the Usual Bridgelux Knockoffs. 48 with optics are about a single 250 watt mh equivalent. Without optics close to a 175 watt mh.

Hope this helps

Live Rock
Water Quality (RODI) and quality salt.
