This is my DIY light. Retro NanoCustoms heatsink,2x 11up retro boards from NanoBox Reef with 2 channels- Ch1: 8x Luxeon ES Royal Blue's 4x Luxeon ES Regular Blues,2x SemiLed 400-410nm Violets,1x VioSys 430nm Hyper Violet. Ch2- 4x Luxeon ES Neutral White 4x Luxeon ES Warm White,2x Luxeon ES Cyan,1x Luxeon C Mint all at 700mah.
If you go DIY light for a 10g (I'm huge into DIY and just got done building a light) I would do:
-MakersLed 12" Slim heatsink-$32
-MakersLed Basic 2up 2 Channel Dimmer-$20
-Meanwell 700mah LDD Driver(2)-$14-$16
-Meanwell CLG Power Supply-$30-$40
Channel 1:
-8x Luxeon ES ($2.50 ech) or SunPlus Royal Blue's ($2.00 ech)
-2x VioSys 430nm Hyper Violet-$4.00 ech
-2x SemiLed 410-420nm Violets-$4 ech
Channel 2:
-2x Luxeon Neutral Whites ($2.50 ech) or SemiLed Neutral Whites ($1.00 ech) and 2x Luxeon Warm White ($1.00 ech)
-2x SemiLed 400-410nm Violets-$4.00 eah
-2x Luxeon True Blue-$2.75 ech or LedGroupBuy True Blue 2pc-$4.50
-2x LedGroupBuy Cyan 2pc-$5.00 (if you want to fill more of the spectrum).
For about a total of $250ish for shipping (LGB and RapidLed are the most expensive),thermal paste,soldering iron and solder and wire.
Or you can use all SemiLed Royal's and Neutral Whites which are $1.00 instead of Luxeon's,stay with the Semi and VioSys Violets and stay with the LGB reg blue and cyan.
