I have used them for several years and like them for a single light source. However given choice I prefer MH with Fluorescent supplementation in which case I use Radium 20K with actinic.
Oh i love the Radiums but my ballast will not run them so iam looking for the next best looking bulb. I have the south pacific sunlight 20k now but i want to try something diff.
I thought you were going to bite the bullet and get some radiums and new ballasts.:bigsmile:
I have seen some nice pics with people using helios 20k try to find out something about them. I think pnoyreefer has shown some pics under helios bulbs maybe pm him and find out if your ballast will fire them.
Just had to remind me Bamachamp that i was going to bite the bullet didnt you!!:squigglemouth: No i still havent ruled that out iam getting ready to order this month i had to get a ring out of the way its been 6 yrs and she was on my back but if the Ushio was close to the radiums that would save me from buying ballast
