lighting people-HERE'S A STUMPER!

[jeninjohnk]

i have thiese ballasts that i can't ID properly. i want some new bulbs but i can't match it to snajay's sight. the ballast reads---ARO electronic ballast (M59) model lmh 220-400. yes they are 220v no problem there. my question is are they elctronic ballasts that are equal to a m59 magnetic ballast? i have run xm20 k+reflux 12k on them but without know what exactly it is. its kind of hard to make a decision on what my next bulb will be. looking for a bluer bulb. i know radium-rigth, swapping them out every 6 months is not going to happen. if i can get a cross to one of sanjay's ballasts then i can make an informed decision. any help would be great. thanks john

"M59" is an ANSI code that tells you that it is a400w magnetic probe start ballast Just google "M59 ballast"

On Sanjay's sight, look at Mag ballasts...there isn't a huge difference in mag ballasts as they are all ANSI rate and have to fall within a certain spec range.

What Jeff said. If you want to run the Radium 400s, you going to need either a pulse start M135/155 ballast, or an electronic. I just switched from the XM/M59 combo to the Radium/M135 combo. Couldn't be happier with the results.

here's were i'm confused--why does it say ELECTRONIC on the ballast? i understand its probaly rated as a M59. just wierd that they would call it that. BTW it is electronic--its small like my icecaps i had previosly. so may m59 is just how its rated?

Can you post a pic??? Preferably one of the ballast, and one of the nameplate on it....that would help ID it
