GT-R Posted January 30, 2015 Share Posted January 30, 2015 Hi need some help to decide no of leds for 3ft sps tank tank is 50G 36x18x18 current setup 46 leds 8 warm white 23 Royal blue 15 cool white Link to comment
farkwar Posted January 30, 2015 Share Posted January 30, 2015 If that's the way you wish to go... 2 strings of RB. 32 1 string of blue. 16 1 string of white.16 1 string of violet. 16 1 string of all the oddball colors everyone usually wants to put in. 16 There, 96 LEDs. 1 power supply 6LDDs, 1 LDD board 6 strings for a 6 channel controller. Instead You may want to consider Philips K clusters. Or run 6 Nano Box pucks down the middle. Link to comment
GT-R Posted January 30, 2015 Author Share Posted January 30, 2015 ok so 48 leds are not enough for the 3ft tank i have to add 48 leds more so total it will be 96 led fixture Link to comment
jedimasterben Posted January 30, 2015 Share Posted January 30, 2015 Yeah, 96 is a bit much IMHO. If you're willing to go a little off what you have now, use six Nanobox 13up boards in two rows spaced 6" apart. Or just copy the same basic ratio and use individual stars. You pay a bit more for them all on one PCB, but it also helps to eliminate spotlighting. Link to comment
NanoFever Posted January 30, 2015 Share Posted January 30, 2015 +1 to nanobox boards. Easy to set up and great lights! Even I was able to set it up. Link to comment
GT-R Posted January 30, 2015 Author Share Posted January 30, 2015 can i add 60 Degree lens to 48 leds instead of increasing the number of leds i have to rebuild the entire led fixture Link to comment
farkwar Posted January 30, 2015 Share Posted January 30, 2015 Yeah, 96 is a bit much IMHO. Not for intensity. For coverage. Anyway, make a string 14, not 16. Will give you more overhead on the power supply. The Vertex Illumina convinced me of this. Long rows of tightly spaced LEDs do what? Simulate diffused T5 lighting with LED shimmer. Expensive lesson, but worth it. The 24" model has 4 clusters of 16, and 3 clusters of 8. Thats 88 LEDs for a 24" fixture, run low and cool. Almost the same amount of light as 6x36 ATI T5 tubes(as I ran it). If it were a 36" Illumina, it would be a lot more. And lot more intensity than you need. Coverage and diffused quality of light, not intensity.

Branching corals, like acros, millis, and branching monti love diffused light. Link to comment
