![]() Nice setup Greg I just skimmed through this write up a couple thing to think about as I went through it when I did my build.
1) I don't think you have enough air flow to cool your entire heat-sink if you run the LED at full blast. 2) I raised my fans about 2" over the heat-sink as this will spread the air flow through the entire array and had them mounted on the top cover with full enclosure except the sides,keeping in mind I used 2 x 120w 4" fans for my array witch holds at least 60 LED (too lazy to count now ![]() 3) If you are gluing the LED on the heat-sink I would use Arctic silver thermal adhesive as I read it in the past to be the best product for heat transfer and use as little as possible. Originally I had optics on all LED and yes if your setup is close to the water you will have a disco affect,I see 2 ways to have it running without the disco dancing water put optics on all white and blue LED and none on the other colors as this will give your colors a 180 degree spread. You are more than welcome to come by and investigate my array ![]() |

![]() Thank guys for the constructive input.
![]() I am not totally done with the fans just yet. Martin & I were checking them before he left for Ireland for Xmas & we both think there will be enough air flow to go around but I have been thinking of adding a 3rd fan & adding in some pieces to direct the air flow into all fins. I haven't picked up the AlumiFix yet but need to this week so I can work on them over the holidays. Also have to build the frame to support the heat sink. I will be putting optics on all the whites ( 45 degree ) & blue ( 60 degree ) but not on the Reds or Greens. My heat sinks well be between 10" - 12" above water level & I doubt it very highly that they will be ever at 100%. Martin also supplies the Arctic Siler to attach the LEDs to the heat sink so that's covered too.

![]() If youare asking the set time for the glue,as I recall after mixing you only have 5 working minutes and it starts to set I beleive full cure takes 4 hours

![]() Sorry forgot to address that question.
From what Martin was saying, just mix up about the size of a dime or smaller at a time because there's only about 10 min working time. Also you only need a dab about 1/8" diameter under each LED, use a toothpick to apply on each LED.

![]() Do you have to prep the aluminum first before gluing the leds on?

![]() Other then making sure the surface if free of any dust or dirt no prep needed.

![]() I ended up with carclo frosted white (wide) optics. It's insane how well they direct the light without really spotting. My lights are 12" from the water.
