View Full Version : metal halide bulb question

06/28/2009, 08:53 AM
I purchased a 72" 175 watt Coralife Aqualite Elite (MH / PC combo) fixture a while back and I'm thinking of bulb replacements.

I'd like to go with either 14K 175watt Ushio bulbs - or - 15K 175 watt Iwasaki bulbs.

My question is: Are these bulbs compatable with the magnetic ballasts in the Coralife fixture? I can't find any technical information on the ballast.

Thanks for the help!

Thank you for contacting us. The light fixture you have requires a bulb that has a M57 Code and is a probe start. The Ushio bulb requires pulse start M137 ballast. The Iwasaki bulbs will work in this fixture as they require an M57 code. We apologize we do not currently offer Iwasaki bulbs on our website.

If you have any further questions please feel free to contact us. We are always happy to help.
