Hi everyone,
So after reading tons and tons I decided the time to change my 6x54w t5 fixture was right... the time of year to chage the bulbs already passed so I want to get this one going!
From the led results and reference thread Ill post some info regarding my build: http://www.reefcentral.com/forums/showthread.php?t=1718642
1) What are the dimensions and volume of your tank?
1.4m x .6m x .6m (55in x 23in x 23in) aprox 500L
2) What type of photosynthetic life are you keeping?
SPS, one Maxima clam, LPS, softies...
3) If this was an existing tank, what lighting did you have before the LED rig?
6x54 T5, good growth but changing bulbs and electricity is a lot of money
4) Describe your LED rig:
a) Model, bin, color, and number of LEDs:
36 XTE Royal Blue @ 700mA and 60 degree lenses
12 XPE Blue @700mA and 60 degree lenses
24 XPG CWhite @900mA and 60 degree lenses
12 XPG NWhite @900mA and 60 degree lenses
6 XML Cyan @350mA
4 RapidLed UV @350mA
2 XPE Red @350mA
2 XPE Green @350mA
b) Spacing or arrangement over the tank:
5 one inch c channels, 40inches long and with 1/2 inche spacing between them... LEDs are spaced 2 inches apart
c) Current you are driving them at:
d) Model of driver you are using:
Using 1 ELN6048P to run the cyan, green, red and uv
2x HLG185H42B to run whites and blues respectively
e) Heatsink, fans, or other cooling:
as stated before, 5 one inch c channels and 3x 12v 80mm computer fans they run @2000RPM with noise @20dB
f) Dimming or other control:
arduino DIY, still working on the code but using the arduino for tests right now...
5) Where did you buy your parts from? Are you happy with these vendors?
RapidLed and Cutter... both good vendors
Here is the first render of how it should look with 60 degree optics
Started building and here are some pics:
Front
Back
it is held by a 2"x2" angle that will help hold the fans and force air to be extracted from the bottom thus creating a greater current through the leds
single LED
TESTING!!
I have been testing single strings with the ELN6048P, after following the advice from Kcress and testing every single LED with my DMM I fire the string up with the smaller driver just for testing...
My problem comes that while running the LED string they start to get pretty hot to the touch and the c channels dont, which would mean the thermal paste isnt applied correctly or not doing its job, im using ceramic thermal compound by arctic, which should be good... is this normal? will the heat transfer start after a couple of minutes? I always turn them off so i wont fry them :hmm5:
Any input is welcome! Thanks!
