Radium 150w 20k DE MH lifespan info needed.
I know there is 250w thread but for us 150w users out there, what is the life span of the 150w 20k Radium DE MH lamp that is run on a Sunpod fixture with a M-81 ballast? Anyone please chime in, especially Hahn, if you are out there. Thanks

What I hear from people who use this lamp 400w and 250w, unknown type of ballast, they usually swap old for new around the 6 month mark.

The 400w is the only one with a short life. Its made to run on european ballasts and is actually something like a 360w bulb. Both the 250w and 150w are true HQI bulbs and should have normal lives.

If thats the case, then I may have to try them out. They are 150w Par monsters. PPFD 47 on an M81 ballast. An AB 10k has a PPFD of 50 on the same ballast.
