You should probably just sell off everything and start a coldwater tank

Take a video of it. Start out in a normally lit room and then turn it on and show the difference. Either that or point it at a wall along with another light like a halide and take a picture of the light pattern and differences in color and intensity.

Are you talking about the thermal switch? If so, I have an extra one in the garage I bought thinking that I would build a second fixture and I havn't had time yet. If your free on Saturday the 19th I was going to have the club meeting at my house and you could have that one for what I paid for it ( like $3.00 I think) Here's a link to what I bought : http://http://www.ebay.com/itm/180549429563?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Yeah without an optic lenses to concentrate the beam it casts light almost straight out to the sides so 140 degrees is pretty accurate.

So I'm starting to build a second one of these lights now. So this is what I have purchased so far for this build: LED Driver Waterproof IP67 Power Supply 33VDC 1.5A 50W $14.99 shipped Temperature Switch Thermostat 55 °C $2.83 shipped I'm still looking for the best deals on the other parts, but all I need now is: Heatsink/fan (probably from goodwill again about $5) LED lens optic ( havn't decided if on 30 or 60 degree angle ye, ebay $9) 50w LED chip ( just looking for the best price still, so far its ebay for $21 shipped) Light housing ( I'm going to mount this one in a round metallic tube for better ventilation since it will be hung as a pendant, Home depot $6) Power supply for fan ( free, scavanged from any 12v converter plug) Other than that its just a little bit of wiring, soldering, heat shrink, and some epoxy to hold it all together. Total estimated cost is less than $60 for the equivilent of a 250 watt halide that only uses 50 watts of power.

Got the old setup fully functional and wired in a thermal switch. It has been working flawlessly for almost a month now. I gutted a track light housing and removed all the power contacts from it so its not actually receiving power from the strip, just utilzing it for a mounting position. Its over my 200 gallon coldwater and is all the major light source, I'm using a couple dimmable 12w blue/white par38 bulbs for color a little and to get better shadowing in the tank. For anyone interested in seeing this light in person, I'm hosting the monthly club meeting at my house on November 19th (which is also my birthday ) The 50w chips individually you can grab for a buy it now price around $25, and the waterproof drivers individually for $14.99 on ebay. I wish I could afford to grab more than one at a time to bring down the price, lol, maybe some day.

Got all the fish and inverts moved over to the 200 gallon from the 110's. Did a little aquascaping, but really all there is left to do is paint the back of the tank ( I know I should have done it before I filled it, but I wanted to see what it looked like clear first, lol) and place a few more barnacles with corynactis on them that I have still in the lobster tank. I think I may add more sand to the left side. Photo and a quick shotty video I took.

Its all up and running, but I still gotta mess with the lighting. Got it hooked into one of the 110 gallon lobster tanks. Selling the other lobster tank on sunday. I was able to use almost every drop of the water from the lobster tank I am selling, so I only had to mix up 90 gallons of new water to go into the tank. Once it was all hooked up there was 220 gallons of cycled water and 90 gallons of new on the 310 gallon combined system. I'll post more pictures of it once I get a chance to go collecting and stock it up a bit

Just waiting for the concrete to dry, then I'll have a nice level spot in the garage for the tank Got everthing painted and mocked up, also cleaned up the plumbing a little bit. Still gotta paint a few pieces but thats it, then water.

The light on the right is a dimmable 12w Par38 bulb with 6 blue and 6 white and 30 degree optics. The light on the left is a 50w led with 60 degree optics.

Video I took of my tank today while I was testing out some lighting options.

Muuuuuwwhwhahhahahahah its ALIVE!!! I got my thermal switch in the mail today so I dug out the old 50w led chip that is half fried and wired it back up. It still puts out a god awful amount of light for only being 50w. I hooked up the new heatsink and fan and mounted the thermal switch onto the heatsink inline to the led. I gutted out a track light fixture and mounted everything inside of the housing so that it can be positioned on the track with the other lights I'll be using. I'm letting the glue dry right now on the optic so it'll stay in place, but it should be all ready to go tomorrow.

My neighbor Jerry stopped by tonight and I think I may have him talked into making that 3/4" thick tank he has into a coldwater

More plumbing done today, built another auto feeder. I just have to paint a couple things, move it into place, and level out, then its ready to be filled and start cycling. Last pic shows the new auto feeder I had to make since the plumbing on the other one didn't work with this setup, plus side is the old auto feeder will fit perfect under my small indside coldwater tank

Took US forever, the 90+ heat yesterday sure didnt make it go any faster.

Water tested and 90% plumbed. Just gotta get it in place, plumb in the auto feeder, and hook it into the lobster tank now.

Thanks guys I'm glad it turned out as good as it did. I read through just about every thread on every forum I could find about spray foam backgrounds, then took the knowledge and info that others had shared and applied the bits that were relevant to what I was doing. A few test pieces, and some experimenting on the side and boom I'm going to do the same kind of background on my smaller coldwater tank for indoors as well.

Started plumbing the closed loop on this tank now.

Here's some pics of the rock work now that I have it all painted and blended in together.

Got it at Home Depot, its made by Behr called 1 party Epoxy Concrete and Garage Floor Paint. Comes in white and gray, but you can ask them to add color to it if you want. I only comes in 1 gallon buckets though, so if you only need a little bit I have some. I bought a gallon and divided it into 4 quart containers and had them mix me 4 different colors of gray.
