Nevermind.. I saw HPS in the link and thought of HPS..
the ballast is rated M59.. thats a probe start (american bulbs) in the 400Wattage varity
It does seem to look a little rough *they are rough looking but that one has a bit of
extra dust or dirt on it..
ANSI rateings for ballasts..
pulse start at 400W is "M135" and HQI ballasts are rated "SON AGRO"
and to run the Iwasaki 6500K 400W bulb on a magnetic ballast you would need a H33.
alot of people are telling me to go electronic with MH
.. Im not quite convenced yet but it
is holding me back from building..
