Well Jim and Andy have me thinking about LED's. The problem is I know less than nothing about them. I guess you can make a black molly look like a rainbow wrasse with them though.

I have a 130 gallon that is going to be an SPS tank. Their is a single brace on top right in the middle of the tank.
So figure 2 sections 33" length x 17" side x 22" water depth. The lights will be in a canopy and I can put them 12" above the water. I would like to mimic the color of Radiums and have them dimmable.

  • Can this be done with 2 DIY fixtures?
  • How many lights will I need for sufficient PAR and coverage per unit?
  • What is a ballpark price for this conversion?


Some basic questions to get me going, I just put new bulbs in so I have a short year to decide if this is the route I want to take. Any input is appreciated. Trying to get my feet wet for now. Pictures and experiences are always welcome.

thanks.......chuck
