update i ran it at 120V 50Hz, again it seems to run Ok a tad hotter then 110V 50Hz but its not so hot i cant put a finger on it with out getting instently scorched Very Happy

Hmm. I'm not sure if 60Hz ballasts should be operated on 50Hz power. Neutral i suppose it's better than using 50Hz ballasts on 60Hz... my first working HID was a 175W MV yardblaster. I always thought it was a NEMA head until someone pointed it out to me. Sad oh well lol. pretty soon i'll have a true 1960s NEMA from jace. it's 100W MV and made by Westinghouse. Cool

acshely its better to run a 50Hz ballast on 60Hz it runs cooler Smile and yea wen running a 60Hz ballast u need to wach it make shore it dont get to hot in this case it runs Ok Smile

interesting... I thought it'd be the opposite. Why are there different frequencies of electricity anyways? Wouldn't a higher frequency be "better" for lights since they would blink faster thus the eye not detecting it as easily? is one more efficient than the other or is it cheaper to make a certain frequency in one place and cheaper to make another frequency elsewhere?

Cool, a yardlight was my first HID fixture too. Mike, ballasts designed for higher frequencies have two advantages, one there are less ballast losses on higher frequencies so a lighter core and coil can be used. Two like you said the flicker is less noticeable and I guess three most fluorescent lamps are more effiecent on higher frequencies.

Strange that it was on UK ebay. Someone may have imported it and then realized the voltage was wrong. You might be best off by using a 240v/50Hz 150w SON ballast with the ignitor disconnected - the 175w mercury lamp will run at the proper current with that, and you have the option of using SON or metal halide lamps easily too. If the ballast is welded to the socket assembly on this light, that would be a problem, though.

I know y this was in the UK(a colector went to the US and got this now he is leeving the UK so he is having to sell most of his coltion). and yes i know how to run a 175W MV bulb here if need be but this runs fine on 50Hz the ballast is welded too a braket.

nice to see a yardlight over there!
