What drivers would I use with a 5 channel 100w multi chip like the "dream mix" in the previous posts? I plan on using an Apex to control the drivers.
Minimalistic multichip DIY LED build
- Thread starter maglofster
- Start date
Most of us here recommend meanwell - something like 2 HLG80-36B, one for white one for blue, and an LPF60-36B for the 420nm. Something along those lines, or two HLG100-36B and an LPF60-36B
These chips can be driven to 252w, although keeping some headroom is not a bad idea. hence, 80 + 80 + 50 = 210w, assuming you were using a color mix like that and needed that much power.

The common MeanWell ELN-60-48 (D for 1-10 V, P for PWM) would fit also for the 5 channel "dreamchip". Both for one chanell (posibillities for overdriving) and for two parallell chanels (no overdriving) This chip will be a reality rather soon - it will probably be ordered after this weekend.

this "dream chip" you speak of sounds great! cant wait to see what to see how it looks!
someone could make band if they setup a site where you could order custom mutli chip leds. and it would help us reefers out so much too!
leds are dirt cheap to make, if someone had a good enough contact with a manufacturer (china) it could be done
If you can find slightly larger tubing, say 125mm (5") you should be able to use the CNPS8900, which is rated for a 21C rise @ 150W heat load. It has an OD of 121mm. I have one of these couplers I machined on my lathe so one will fit, the sidewall in that area is a bit on the thin side but not excessively so; The mounting point is intended to be lower anyways. This is the heatsink I intend to base the dream chip fixtures on. The fan grilles I am using are "110mm" and for these fixtures, I need to bend the legs a little to make it slightly smaller; you can see this in the picture.[/QUOTE]
Question, Would I be able to mount the 8900 directly to the underside of my hood or would I need some type of standoffs for it to be able to pull air in? I'm wondering if it would pull enough air in between the fins? My problem is I have about 10" top of hood to top of water, so the low profile of the 8900 looks good. Thanks---Rick

Talking heat sinks while this might not be great for the high powered ones look at this idea.
http://www.heatsinkusa.com/3-500/
On a 48" long tank it would be able to handle 36 5 Watt LED's which driven at 1500 ma would actualy give you 187 Watts of LED Lighting. Now if you have a 75 gallon tank you could run just two of these one near the front angled to the back and a second near the rear angled to back to give you that maximium shimmer effect some of us miss from the old Metal Hides. With the potential of 375 watts of power you would be able to bring it being brighter than someone running 10 HO T-5's.
Cost roughly
Heat Sinks = $98.00
LED's = $245.00
Drivers = $238.00
misc hardware $50.00
total $631 and you have a dimmable system capable of even lighting a 180 gallon tall tank.

Lasse is there any more information about the 5 channel driver you mentioned on the group buy thread? The group is very close to the trigger number so if the buy is happening soon (this weekend, YESSSSS!!!:hb2
I would want to hold off on buying my meanwell drivers if janne's driver design is imminent. The waiting is excruciating.:hmm3:

The Driver mentioned has a data sheet here.

This is not a 5 channel driver. However the Multi-Chip LED is 5 channel.

You have to be patient
This is saltwater - It is spelled p a t i e n c e It is under development and not tested yet so we are waiting here in Sweden too. Probably it takes around three weeks before it could be tested in real life. Here in Sweden, I know that he is going to sell the final product when he is done with the testing. He has buy chip also - just for testing purpose. I´m going to publish more details later on at SDR:s forum because of the policies here at RC. I do not want to voliate the rules here. @ TopTrea: He refers to a the driver solution to a guy here in Sweden is developing for this 5 channel multichip. A solution that is quite small which means that you can insert it into the pendant directly and let the fan that cools the chip also cooling the driver card. This means that you only need one cable for 36 V input to the pendant. But the solution is still under development.

Well I personally will be going with 3 drivers per, but there's no reason you can't drive more than 1 chip with a single driver, the voltage binning on these things is normally good enough for that. What I will be doing is running one driver for white, another for blue and a third for violet. I don't see any need to control the 10000k and 15000k individually. I will try them seperately to be sure though.
I'm not sure if I understand what you're trying to do.
What are you trying to power? For a PC power supply you need to open the case up. For 12V use the yellow wires, for 5V use the red wires, and for Ground use the black. For the power supply to run you need to connect the green wire to any black wire. All of these wires are located in the big bundle of wires, not the main power wire.

This thread is why I became a member on Reef Central and this is my first post. Im starting my first reef tank. Ive had fresh water but never saltwater. Im going to order 2 50w 10000k with 90 degree lenses and 2 20w 420nm with no lenses for a 65 gallon. Ive done a lot of research on lighting and this thread is just blowing my mind. I cant wait to have a budget led setup that is this good.

CanadaChop, we all look forward to see you build and make sure you post some details on the build too. Welcome to The ReefCentral.

This 36v driver set excludes the use of(28v) red chips unfortunately.
