HI m new in the hobby i want to build a led fixture but idk what combination of color i have to use and how many leds i need ? ? ? i was thinking build something with those led but not sure what d u think guys.... ? my tank is 65 gal 38x18

10pcs 3W High Power Cool White LED Light Emitter 6500 7000K with 20mm Heatsink | eBay

10pcs 3W Royal Blue High Power LED Emitter 700mA 450 455nm with 20mm Star PCB | eBay

1W 420 430nm UV LED Blub for Aquarium Fish Tank with 20mm Base | eBay

 

1 Get good leds from a good source, LEDgroupbuy and stevesleds have great ones
2. UV leds shouldn't go over reefs, and they are usually TV and low quality. HV from ledgroupbuy peak at chlorophyll A's spike at 428nm
3. I'd highly recommend reading this Lighting spectra, Photosynthesis, and You (new plots!) - Lighting Forum - Nano-Reef.com Forums and looking into Evil Clusters, which uses a true NW bridgelux around I think, well it's huge surrounded by Royal Blue (450nm or so), and sometimes Cool blue (470nm or so), HV(430nm or so), DR (680nm or so), and cyan (395nm or so)

 

i know m trying to go cheap cuz is only a test i never do a led fixture before (no skills) , i dont want to spend to much money and later regrets....

 

there's this seller on eBay called joy-deal. look up his store. i ordered all my LEDs from there and they are all still running except for 2 that I shorted out...ooops :-o. And the selection and pricing are great. Plus free shipping. only have to wait a few weeks to get to you on the china express shipping.

 

rcflyer1388 what is your setup ? and if have pics....

1.0reef thanks fior the info .. you also have a led fixture ?

 

I have a few
Just don't get leds off ebay unless you really know what your doing, 90% chance all the leds on their are either knockoffs or low quality. Email LEDgroupbuy, or Stevesleds, you could use 12 watt Luxeon M's or Evil Clusters

 

I have a 55 tall....using 36 3w chips from Joy-Deal and 2 mean well dimmable drivers with 1 regular driver from joy-deal (9-12 Led). I started putting sps in my tank about 2 months ago and they are growing at a nice rate. I use a mixture of 65k white, royal blue 1:1 ratio and the rest reds, blue, and UV. I don't use optics since I like to keep my fixture low and I hate glueing those stupid little optics on the chips. The heatsink is from RapidLed when it was $20 off. I love in an apartment so I can't make anything too permanent. Here's a few quick snaps with the photography grade iPhone lol...

 

1.0reef i understand but m not looking for the best now m going to test my skills only

rcflyer1388 look nice except the last pic to much purple for my taste ...

thx you both .

 

IMO some Luxeon M's (From stevesleds) in NW and RB will be great.

 

idk why it comes out purplish every time with this phone. I can assure you it's not lol. it's more of a whitish blue look.
