Red/green "full spectrum" LED?

ReeferMatt · May 15, 2013

I have been looking at new LED fixtures and have noticed a lot of these red/green units. http://www.ebay.com/itm/2x-Pack-Col...t=LH_DefaultDomain_0&var=&hash=item4d093763a6 Now the reviews seem mixed at best, some say that the reds and greens although unusable for coral photosynthesis, provide a visual spectrum that makes corals "pop" with color, much like my use of purple+ in my t-5. Yet others say that the bulbs are not only a waste of time and wattage, but will grow nuisance algae by the boatload. I wanted to know what you guys think about these lights, or am I just better off looking at a traditional royal blue/cool white fixture?

Oh, and I thought I would also add this article to the conversation: http://www.reefbrite.com/benefits-red-green-leds-science-or-hype/

I know I started this same conversation on an old post, but I moved it here to try and get more input

I know there was a recent thread on the dreaded RC site that addressed this a bit that seemed pretty in depth. Reply so subscribes and I'll find thelink when I'm home. (Kinda covers str vs weakness of led spectrum, and where a t5 supplement, esp blue plus is good for certain wavelength.)

As far as red/green in general I do know you need to be pretty conservative. like 4 leds in a 60gallon, and even in a big 120 only 8-10 iirc. Can overpower stuff easily, but does help a lot with pop.

Red/green "full spectrum" LED?

I bought the Chinese dimmable LEDs with the green/red. Don't see any nuisance algae popping up that I didn't have before

Red/green "full spectrum" LED?

I sure see a lot of these different colored LEDs showing up on the higher end LED fixtures so im thinking there must be a reason these companies are starting to add them. They seem to add only a couple of the red/green/whatever color LEDs so I think it is all for color pop.

Please note: All those chinese fixtures use bridgelux LEDs and worse. Be prepared to have to replace the LEDs every 2-3 years. They have a short lifespan for LEDs.

Also, on the topic of color spectrum. The reds, greens, and cyans can cause nuisance algae. But worth it in coral growth. I combat the algae growth with an algae scrubber in my sump.
