LED conversion on 10g horizontal scrubber

[kerry]

Here are some pics of my LED scrubber on my 10g horizontal that I have been working with and talking about in a couple other posts. Its made with (4) 3W 660nm LED's, the screen is 2.75"x6.75" horizontal mounted. The growth is much more dense with the LED's and faster as well. The pic of the growth is 4 days worth. I hope to get better pics this weekend maybe. That red algae stuff is tough!!!! (edit: the LED's are 2" away from the screen)

Hello!

Thats look great, looks as it grows very well with algae in just 4 days to be an horisontal scrubber.

Is the screen totally submerged under water?

Its not submerged so to speak but the flow is so heavy that it is under water technically. Seeing I have so much flow I thought about making the LED's closer. They are at 2" now and I thought about cutting that in half.

Impressive growth for just four days. Would take me a week to get that kind of growth. :lol:

What LEDs are you using Kerry? That is good growth for a few days :)

Ebay, this is the place: http://www.ebay.com/itm/3W-High-Power-R ... 1c1f93e81b (http://www.ebay.com/itm/3W-High-Power-Red-660nm-LED-Specialist-plant-DIY-/120788871195?pt=LH_DefaultDomain_0&hash=item1c1f93e81b) . I also got the 4-7 LED driver as well but it needs more then 4 LED's or it blinks so I put 4 12,000k's over my display as well. It runs 8 just fine. I got the adhesive heat sink stickers and heat sink from rapidled.com. One note on the heat sink. I was at Lowes and got a piece of channeled aluminum and it works great for a heat sink. About 8 bucks for 3 or 4 foot. So I would suggest Lowes for the heat sink (in the hardware section, aluminum channel), this Ebay place for the LED's and driver, then rapidled.com for the adhesive heat sink stickers.

Ooh, didn't realise you made them yourself :oops: , but they seem to work really well. A bit too difficult for me I think.

I hope to get some pics this weekend or the next on how they are assembled. Its really very simple if you can solder wires and tell the difference between positive (+) and negative (-) wiring. You can get adhesive thermal stickers for the LED's so mounting them to the heat sink is easy. I am going to mount the ones for my display area in a eves trough (gutter) since its the same basic shape already.

Do you think these (http://www.ebay.co.uk/itm/DIY-3-x-3W-Red-Grow-LED-650-660nm-w-Driver-Heat-Sink-12VDC-Input-Aquarium-/220866293590?pt=LH_DefaultDomain_0&hash=item336ca82f56#ht_2059wt_1270) would do the trick Kerry?

Those should work just fine, you may not want to use the three lens covers. I tried lens's and it burned the algae. Those are basically the same specs as mine. The price is right for them to.

[Marksfish]

Great, think i'll order some to try :D Thanks very much.

but someone used the red led at 730nm?

[kerry]

I have not tried the 730, I only have used the 660 and know that they grow good algae. The 730 might work good as well, maybe someone here has info on this 730 LED.

My LEDs turned up today Kerry, just need to try and work them into my scrubber. Thanks for the pointer Kerry.

Awesome!! I get really dark green thick growth with my horizontal scrubber LED now. I am going to make it vertical in the next couple weekends or so. Been working on getting the new performance transmission rebuilding business going in my spare time lately.
