A few years ago I switched from 250w MH to Radion led, gen 1. Although I felt the blues and purples were unreal I always thought the reds fell off. But I also new I did not want to run MH for more than 4-5 hrs a day. I have never used T-12s but have been reading people commenting about their success with them. I also new I did not want to run them for the full viewing time either. So my solution was to combine the three. So for now I will be using 3 radion gen1, 2-400w mh with blueline ballast in lumenarc large reflectors, and 4-60" T-12s.
After looking at many setups I decided to use EZ-tube, thanks to glassreef.com. The aluminum tubing is lightweight and user friendly. As you can see below the leds and reflector sit on a flange held inplace by the 1"tubing. The leds are sitting on rubber bumpers holding them laterally and giving a void for heat.
When thinking about the amount of lights it would take I new they had to be movable and adjustable. Thinking about a rail system the pocket doors in my house came to mind. A trip to HD and I had a simple solution to moving the lights. With the light rack at 40" and the standard rail coming in at 72" it almost completely removes it from over the tank. When using the radions over my 180g I used their hanging kit. Two kits and it works great. I tried to come up with other/better options but was unsuccessful. I would of liked it solid but just could not come up with anything. Thought about snap lock tubing but could not find it. The top rack allows one person to move it. It will also allow me to add more support if deemed necessary.
Currently the t-12s are not installed. I did not have the aluminum plating last weekend when putting it together. Hope to have them added in the next few weeks.
