DIY LED for 120G (Half ordered!)
I am not a DIY guy, I don't make my own dried goods, my own filters or diffusers or anything else like that! But, today is different, I plan on doing my own 40+ LED fixture for my 120 Gallon tank (48x24x24).
This is a thread for advice on my current stock list of equipment, once I feel I have the right list I will order and begin the designing stage of the fixture and separate housing for the Drivers and timers. I currently have an idea for an industrial looking fixture. Maybe an Airplane Hanger style (Half Circle) hanging with a couple of fans. Something to that effect.
I will update this thread as much as possible and I hope all the LED DIYer's lend a hand!
Feel free to ask questions or give advice!
So this is the current list of parts:
3 1-48HS 1.1" x 48" Aluminum Heatsink $44.00 $132.00
1 DDC-01 DDC-01 PWM Controller $59.00 $59.00
3 ELN-60-48P Mean Well ELN-60-48P dimmable driver $34.00 $102.00
42 XM-L Optic Degree: 60 $2.48 $104.16 (is a 60 Degree optic good for a 48x24x24 tank?)
21 CREE XM-L Cool White T5 $6.80 $142.80
21 CREE XM-L Neutral White T5 $6.95 $145.95
50 Thermal Tape Preform 20mm Star $0.69 $34.50
Close to 750. Not including the optional and expensive-because-of-my-taste stuff like the enclosure build, hanging kit, Timers, Digital AMP meters, Misc wires and stuff.
Plus I also want to add a 4th row with about 4 Ebay LED's since I wont have any shimmer with the amount of light coming from 40+ LED's. It'll be a cool white moonlight with no optics, just for the shimmer effect when the main lights are off. But this will be later on and I am in no rush for this feature.
Each of the three rows of Heatsinks will have 14 LED's spaced out 3.5 inches.
One of the few concerns so far:
I want to go with a Cool white and a neutral white. I am thinking that would be on the bluer side to the eyes correct, like a 10,000k T5? Do you think an even split of those two colors would be sufficient? I Don't want too much blue, but I would like the greens and a couple of the reds in the tank to pop!
If I wanted to add an Arduino (spelling?) system later on, would I be able to do it with the three 48P's and the PWM? I don't want to close myself in and not be able to upgrade for future software.
