i obtained a used 180 that i have been working on for a while and i am at the point of figuring out the lighting. It came w/ a really old hamilton system pictured below. It has 2x 175 halide and 2 40 watt t12s. Is that enough lighting over the 180? I plan to keep softies/lps in the future. I have no idea exactly how old the light is but judging by the age of everything else, its ancient.
Can i use any other bulb in there or i am stuck w/ 175w?
a pic of the ballasts (looks like a magnetic)
If i cannot use any other bulb, i was going to go with this: (note, i am not the seller, just showing these for feedback)
