Radium 400 watt SE

[The Saltman]

Hi guys,

Do you have to replace these halides every 6 months?

 

[Znut Reefer]

Not if you use them on e-ballasts. I replace once a yr.

I have magnetic sunlight supply ballasts

If you have the M135 ballast the bulb will last longer because it driver the Radium with it spec... Even Electronic ballast will slightly over drive the bulb....
