Well the above was all nice. I was looking at 2 forums back in 2007 after the tank had been up and running for 2 years and I only posted once on the other forum. The other forum is not as lively as this and things have happened. The tank flourished with minimum support. The plants spread and filled out and once a year I changed the 4 VHO's. That was ok for 4 years but then the price of the VHO's got a bit pricey, I was having issues finding them and they have not been changed so all but 2 plants have died off. Yep you really need to change tube lights once a year. The plec outgrew her vase and so we made a ceramic tube which she made her own.
In September of last year the wife said hey what did you do to my plants? I said the lights need to be upgraded and I think it is time to transition to LED.
I spent a few weeks reviewing the machinations of O2Surplus – someone has too much time on their hands. He has the most impressive home builds. Fissure in Sweden also had a real sweet set-up. Tank envy. I determined that as much as I thoroughly enjoyed the improvements of the O2Surplus Control system I really needed something that was more turnkey. I knew that I would not have the copious free time needed to fully appreciate the freedom of the board.
Taking the lumen/lux spreadsheet from Hoppy I played around with a few options. I initially was going to use the Cree XML2 LEDS but a few conversations off line with LEDGroup Buy offered a slightly cheaper solution of using the XTE. Well there is an offset to it. The Hoppy spreadsheet resulted in almost twice as many LED's. Then again you can tweek the driver run 'em harder and use fewer. Arrgggghhhh so many choices.
Time to start accumulating parts and pieces.
30 Cree XT-E white (cool white), 327lm at 1,000mA
30 Cree CT-E white (warm white), 252lm at 1,000mA
6 Cree XT-E RoyalBlue 1,050mW at 700mA 450-455nm Moonlight mix with CW & WW
4 Meanwell LDD-1000H LED Driver
1 Meanwell LDD-700H LED Driver
1 MakersDRIVER 5UP Pro – Drive
1 MakersLED 5UP manual dimmer
1 Makers Controller
48 inches of heat sink
lazy man's method of attaching via BJB Lens Holder and Star connectors
1 Power Supply SE-350-48/70230339 need about 230 Watts to run the full setup
1 Power supply for the 4 fans.
Once all of it arrives I will determine if I can adapt the wood hood to house the metal one and use the flow through fan.
The parts a trickling in. The heat sink (sled) came in first. I have yet to unbox it but I have verified the drawing to the part.
I do not like the idea of gluing the lens onto LED so I started looking for other alternatives. One option is a BJB base and lens holder
The hunt was on for a 60degree lens that would fit in the holder. Critical dimensions are the diameter of the lens lip and height. One possibility if the lens is too tall is to end mill the base of the holder to get about 2 mm more clearance. I bought a few lenses and determined which ones won't work and by chance found some on e-bay that would.
If the sled fits in the light box I will not need the four fans that came with it. I should fully unbox it to make sure they are in there. Otherwise the extra power source will get the fans spinning.
the current power source for the Ice-cap is mounted on the wall behind the light box. I could mount the power source in the same spot or put it in a box and mount it on the wall behind the cabinet. Jury is out. I am leaning to keep it off the ground and above the water line.
I will put up a photo of the led layout next
