TheStar Posted March 14, 2009 Share Posted March 14, 2009 How long is that tank? L-16" x H-14" x W-16" which includes the area in the back for the filters, etc.. Link to comment
serval Posted March 14, 2009 Share Posted March 14, 2009 Evil, interested in one that would work, for a tank 30x20x22"H. Love the kittehs; the dumacat says hi. Link to comment

Keep your eyes peeled. Evil, interested in one that would work, for a tank 30x20x22"H. Love the kittehs; the dumacat says hi. Pretty kitteh. Hmm, wide tank. I'd have to figure out how to do that one.

TheStar Posted March 15, 2009 Share Posted March 15, 2009 I have plans for a 16" fixture. Keep your eyes peeled. Cool, its a nice little tank but its kind of at a standstill. Some serious lighting would add a whole new twist. The stock hood/lighting generate so much heat, going topless seems natural. Link to comment
neelix Posted March 16, 2009 Share Posted March 16, 2009 No updates yet. Still working on getting my first fixture running. Certain events around the household have slowed things down unfortunately. I was hoping to be finished with it by now. I'm pretty confident in it's potential performance though. Fingers crossed for next month. I'm hoping to do a group buy for more LED goodies, and these might be one of them. Let me know, if you need someone to participate, any thoughts on going modular like AI for us 120 gallon folks? It would provide more options and less expensive heat sinks. Link to comment
dailydriven911 Posted March 16, 2009 Share Posted March 16, 2009 I have been talking with some people about doing a 36" unit. I still have to figure out some of the details, but it's looking to be in the $750 range. It will have the same basic design (which I will be posting images of, I promise), just longer, and more LEDs If there is interest, I can push a little harder on getting it sorted out sooner. I think you will have plenty of interest! I'm starting my 40b project right now and would love to get my hands on a 36" fixture. Hope to see more progress soon! Link to comment
evilc66 Posted March 16, 2009 Author Share Posted March 16, 2009 Let me know, if you need someone to participate, any thoughts on going modular like AI for us 120 gallon folks? It would provide more options and less expensive heat sinks. Hadn't really thought about how to approach this. The way I set up the arrays for constant coverage doesn't lend itself to a modular approach just yet. Maybe in another revision. Right now the best coverage comes from making the fixture specific to the tank. I think you will have plenty of interest! I'm starting my 40b project right now and would love to get my hands on a 36" fixture. Hope to see more progress soon! Soon enough. After I get the plumbing somewhat situated on the new tank, I will be able to put more time into the fixture. I was hoping to have it done by now. Link to comment
beachbabe Posted March 18, 2009 Share Posted March 18, 2009 I have plans for a 16" fixture. Keep your eyes peeled. How far in the future do you believe this would be? I'd definitely be interested in a 16" Link to comment
evilc66 Posted March 18, 2009 Author Share Posted March 18, 2009 Not sure yet. Depends on how my first prototype goes. Link to comment
Reefer Al Posted March 19, 2009 Share Posted March 19, 2009 Hey evil, I was thinking about how you could get a modular array or a heatsink that is smaller than your sandbed to cover more area. You could go to a local machine shop that deals with aluminum and get them to machine say 1/4" deep holes on a certain degree offset. Say the outer leds on the heatsink were aimed 10 degrees from the center of the fixture, the center leds were aimed straight down, and the all the leds within the outside and the center were aimed very slightly outward. You could get better coverage and if you used narrower optics on the outer leds than you wouldn't sacrifice too much par. Link to comment
evilc66 Posted March 19, 2009 Author Share Posted March 19, 2009 I have thought about that on numerous occasions for certain applications. Don't think I'm quite prepared to spend the money to get it machined just yet, unless you guys want me to adjust the price accordingly? Right now, the 8.5" heatsink works fine on tanks up to 18" wide. Wider than that and I would go with dual 5.375" heatsinks. Link to comment
Giga Posted March 19, 2009 Share Posted March 19, 2009 I was going to buy some lighting but I may have to wait till I see these Link to comment
ximmortaldeathx Posted March 20, 2009 Share Posted March 20, 2009 Im also interested, please PM me when finished with the product! Link to comment

My dad has some machining equipment that we have used for drilling, leveling, cutting, and bending steel. I have seen aluminum catch on fire before and Idk if I would feel comfortable working with it. But I am considering the much cooler possibilities of it. Link to comment
chazde3 Posted March 22, 2009 Share Posted March 22, 2009 I have seen aluminum catch on fire before ??? Are you sure it wasn't magnesium? Link to comment
evilc66 Posted March 23, 2009 Author Share Posted March 23, 2009 Seriously. Aluminum is one of the easiest materials to machine, and won't errupt in fire for damn near any reason. Link to comment
Pcyc Posted March 27, 2009 Share Posted March 27, 2009 Seriously. Aluminum is one of the easiest materials to machine, and won't errupt in fire for damn near any reason. yes it is, thats why its a favorite. Link to comment
vivereilmoment Posted March 29, 2009 Share Posted March 29, 2009 How are you coming on the prototypes? Looking into doing a 20L when I get my scholarship money for summer, maybe I could send some your way if the LEDs are ready... Link to comment
evilc66 Posted March 30, 2009 Author Share Posted March 30, 2009 Tank is up and running now, so I will have more time to focus on the prototype. Might be a few weeks before it's finished though. Link to comment
chazde3 Posted March 30, 2009 Share Posted March 30, 2009 Seriously. Aluminum is one of the easiest materials to machine, and won't errupt in fire for damn near any reason. Help help, my aluminum burst into flames! omgomgomg , I'm not sure if that's even possible. Not while machining at least. Link to comment
evilc66 Posted March 30, 2009 Author Share Posted March 30, 2009 Not unless it's some bizzare alloy. Link to comment
Tanque Verde Posted April 11, 2009 Share Posted April 11, 2009 I am watching this thread, as I watch all of evilc66's threads, with a great deal of interest. I want more PAR and color options on my 18" x 10" zoanthid tank. Evil's much-hyped but not yet seen superslim actinic light would help with color, but this fixture might accomplish both. And $200 cheaper than the AI. Link to comment
Reefer Al Posted April 11, 2009 Share Posted April 11, 2009 Seriously though my physics teacher was grinding a solid aluminum block and all the aluminum dust caught on fire and we couldn't put it out so we just let it burn out. Aluminum fire hazard This must have been why it erupted. Link to comment
