    I am not so sure its over kill depending on the light your display makes. I only say this because since I have taken my horizontal on the 10G and made it vertical I am getting green algae growing in my tank now. I updated my display LED light (7 3 watt 19000K) before (by about 2 months) my scrubber and didn't have any algae problem. I would however have slight runaway nitrate with the horizontal (up to 30PPM sometimes) and just correct this with feedings. Now I have taken the 4 LEDs from the horizontal and put two on each side of my new vertical. Since doing this my nitrates are great but I am getting algae growth in the display at a real good rate. I am going to add one extra to one side and see how it goes. My screen size is about 2.75x4.5" When I had all the LEDs on one side of a 2.75x6.75" screen I didn't have any display growth.

    Well that makes me feel a little better. Still even if it is, you can regulate the photoperiod. I guess it would also qualify under the double-wattage lighting rule

    I cut it back some but its still making head way, I guess I will have to shorten the display period a little more.

    Ahhh it makes more sense now, it was just a typo, thanks for clearing that up!

    Has anyone used the 660nm reds from satisled?

    http://www.satisled.com/3w-high-powe...70nm_p433.html

    These look like the osram chip but I'm guessing it's a knock off. Still though for < $2 each that's hard to pass up over $5.50 Osram from rapid.

    Haven't used those LEDs yet, but they look much closer to FEDY LEDs vs OSRAM. OSRAM LEDs don't look like any other LED I have used personally, they are an odd looking square instead of round (and why there are no optics for them).

    Here are my FEDY LEDs, one thing if you look closely that you will notice, the Red LEDs have 2 seperate LED emitters side by side inside each chip, so they are "dual band" LEDs. One LED (middle row) contains a 630nm AND 640nm LED inside, the other one (top row) contains a 650nm and 660nm LED inside. Bottom row is royal blue and only has 1 emitter inside. They also cost $1.70ea.

    OSRAM vs Satisled

    vs FEDY LEDs

    Interesting - how has your experience with the FEDY's been?

    Satisled takes FOREVER!! I have them from the last order and they work just fine. They grow algae like the ones I get from http://www.ebay.com/itm/3W-x-10-PCs-...item19ccfc9c02 .

    This is valuable. One thing I'm noticing is that the Osrams (on the Rapid page) have a max current of 1000mA. The satisLEDs say 750. ledtoplights (ebay link above) say 650. So If I am wanting to use a meanwell driver, I could use the LPC-35-700 non-dimmable one for the osrams, but not sure about the other two. I would think those would need a dimmable driver, which costs more, which offsets about 1/2 the savings ($34 vs $16). So would I be OK driving the satisLED or ledtoplights LEDs with an LPC-35-700?

    Floyd, the way I am doing my next build is using 12 LEDs per side on a 6"x6" screen (I know.. WAAAY overkill) but what I am going to use is a Meanwell 1050 constant current driver. Obviously 1050mA will blow up all my FEDY LEDs if I try and use it normally... soooooooo.. what I am going to do is run 2 parallel strings of 12, so I cut the output in 1/2, so 24 LEDs will each get 525mA, much less than the 700mA max they can handle. My thinking is I will have better coverage, less heat, more efficiency, and LEDs should last much longer. I am also going to use (per side) 420nm (1), royal blue (2), 630/640 reds (4), 650/660 (4) along with a warm white (1). Really mix it all up.
