My existing and somewhat successful lighting fixture is a Photon Plus that has two single end Mh 250 watt bulbs and six T5's. I bought it from Aquarium Specialties, one of the few suppliers that distribute it. Cost was $2K. It's a real energy hog and gets pretty hot. Hot enough to heat up my small kitchen noticeably. I recently supplemented this with a single 48 inch Reef Brite blue strip and love the color it provides. I pretty convinced that LED's can provide enough light for my reef to thrive so I've purchased an additional 4 strips from my good friends at Neptune Aquatics, Along with the original blue strip, I've added two more blues and two whites. I built a simple DIY aluminum frame to mount them all. I'm pulling the Photon Plus fixture and hanging the new one today. If all goes as expected, I'll have a very nice combination Mh/T5 fixture to offer at half price from what I paid a year and a half ago. I'll create a post in the Buy/Sell forum in the next couple weeks if all goes well with the LED's. Just for reference, the Photon Plus fixture is passive cooled and is elegant. Pictures will follow once it's up and running.
