cessna driver Posted October 4, 2010 Report Share Posted October 4, 2010 I have completely removed my T8 lighting from my Aquaone AR980 that being 2X30W (6500K & 8000K) and 1X25W (15000K) lamps. I now have 2 X 39W T5HO (power-glo and life-glo lamps) These are dimmable from about 10% to 100% (Less than 10% the high output lamps become unstable.) This is the tank with all 3 of the old lamps on This is the tank with the 2 39W T5HO at 100% brightness 50% (approx) both lamps still on 35% (approx) both lamps on 10% (approx) both lamps on. I still need to make and fit some reflectors so efficiency should improve some more. As a bonus the whole hood has lost about 3KGs with the removal of the old control gear. I still can get 1 more lamp in there but would need to install a fan. Lamps are soft starting with no or little flicker and dim up to 100% in about 1.5sec. I still need to add some components to lengthen my dimming time as well as controlling the air pump and future CO2. I have some undisclosed other features I want to add to it in the coming months :lol: Hopefully my plants grow better. Quote Link to comment Share on other sites More sharing options...
Joe Posted October 4, 2010 Report Share Posted October 4, 2010 Wow that's cool. You have a lovely tank, and those discus are beautiful! Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted October 4, 2010 Report Share Posted October 4, 2010 That's pretty cool. What fixtures are using and how do you dim them? Quote Link to comment Share on other sites More sharing options...
cessna driver Posted October 5, 2010 Author Report Share Posted October 5, 2010 Thanks, I'm using a twin electronic ballast that will also operate with non high output tubes (21W) with touch dimming control (Push button) made by Osram I also needed to change the end caps to suit the T5 lamps and completely rewire the hood. The hood still looks like the stock Aquaone hood from the outside. Normal electronic ballasts / ECG can't and won't dim, a specialized ballast is required The tubes are the Hagen brand Cheers Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted October 5, 2010 Report Share Posted October 5, 2010 Knew about the tubes. Very smart with the ballast though! That's awesome. How did it work out price wise? Quote Link to comment Share on other sites More sharing options...
cessna driver Posted October 5, 2010 Author Report Share Posted October 5, 2010 Ballast was about 200 with my discount. It uses a digital interface and is designed for building automation and connection to a computer so is dearer than the one I intended to use that uses an analogue interface to control the dimming. (was supplied wrong so I took it, but dose allow for more control options) The analogue one would be about 130 ish end caps were about $6 for 4 Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted October 5, 2010 Report Share Posted October 5, 2010 hmmm. That works to be the same as a HO Hood then, with the HO lighting controllers being slightly cheaper I think. Your way and you get to dim the lights which is a huge bonus. Do you get a warranty on the parts? Quote Link to comment Share on other sites More sharing options...
