Over driving NO lighting

I have a couple questions.

I want to overdrive F40T12 Bulbs on 48" Canadian tire/home depot "work light" ballasts.

I understand that you can just rewire the ballasts to accept only 1 bulb which bumbs the output by about 1.7 times. I want to run 3 over drivin bulbs.

Right now I have 2 coralife 50/50's and 2 coralife actinics sitting around.

My questions are:

Does anybody have any experience doing this? Does it get too hot?

Where is a good place in the Vancouver area (perferably closer to Coquitlam) to buy bulds and flourescent equipment?

Thanks

Yeah, if you are buying new bulbs anyways, just buy a proper electronic ballast

Today I purchased 2 PC ballasts, meant to hold 4 bulbs each. I decided to overdrive both ballasts, and have only 2 bulbs in each ballast. I have never seen a PC as bright as this one... and the best part of it is, it all cost $120 with extra 55watt 10,000k bulbs!!

Wiring only took me 30min, now i just need to install them into a reflector and im set.

They do get hot, so tomorrow i will be buying fans from Radio shack to help get air moving in there.

its amazing how a slight increase in visual brightness makes us think it is putting out way more light. when I overdrove my 55 watt PC's for a test I only got a 6% increase in PAR but they looked way brighter.

Do you have a PAR tester then? I have always been curious to test my setup.

I'm well on my way to Nerd, but have to settle with Geek for now. Maybe once I get a par meter, refractometer, pH controller, etc. :mrgreen:

I have over driven t10 bulbs. I noticed my 12" bulbs driven 4x were increadible. When I went to a bigger tank I just added 48" bulbs to the over driven ballasts. I don't think they are as bright as when I was only overdriving the 12" ones. Still really bright compared to not having them over driven. I had these ballast floating around (which is a t8 electric from CT) If I had to spend the money I just get a workhorse 7 and run T5HO, PC or VHO. I think it would cost about the same and you could still overdrive them for that extra bit if you must.

Workhorse 7? And can you explain overdriving and how you do it?
