175 watt MH conversion Bulb??

hey guys, I have a 150 watt HPS light fixture and ive been looking with no hope, for a Metal Halide conversion bulb to work on my 150 watt HPS. Is there one? Can anyone help me, please?! Maybe a 175 watt MH?

I am having the same problem. I called Sun Light and they said they don't think anyone makes one. It would be really nice to be able to get ahold of one though. Does anyone know if they even exist?

Im thinking only if the 150 ballast was hps&mh then you can run a 175 mh, otherwise they dont make an MH conversion bulb for a 150 HPS.

I too have a 150 watt MH/HPS system. Has anyone yet found out if there is any danger in using 175 watt bulbs?

They do exist. I have a 175 MH and can buy a 150HPS conversion bulb. I believe you need a "conversion" bulb not just any 150 or 175 MH or HPS.

Mass, I believe they're in need of a MH conversion bulb, not a HPS. I too have a 250w MH, and I have a 220w HPS conversion bulb so it can run on that ballast.

As far as the MH conversion bulb goes, I am not too sure whether they make one or not neither.
