MH - where should i get em?

[Delphinus]

:shock: Wow, when Home Depot was selling them, they had them vfor $50 or $60, when they decided to stop selling them they unloaded all their stock they did so at $30. No wonder they suddenly flew off the shelves!!

I actually was thinking that maybe the MV fixtures for 175W at HD, were using those multi ballasts. Maybe not though, considering the fixtures are only about $100 or so.

...

Just one additional food for thought. I'm sure I've read somewhere that Iwasaki bulbs are not recommended for use on "combination" ballasts. I have no idea what "combination" ballast means. What worries me, is Iwasaki's are a special case. You can run them on a mercury vapour ballast, you can run them on a metal halide ballast ...... so why shouldn't a "combination MH/MV ballast" not be perfect for these bulbs?? I should mention one of my ballasts for my 75g is one of these ballasts. The other is a used MH ballast I got from hydroponics store and I never opened the casing to see what kind it is (m58 or m58/h36). I wonder if I'm doing damage by this?

I guess I should probably write Iwasaki myself and ask them this question. I should look for some tech support contact info I guess...
