changing bulbs

[jimneedhelp]

i have three 175watt 20,000K HQI bulbs in my canopy can i put 150watt
14,000K bulbs in without damage to ballast?

Do you mean, in addition to them, or replacing the 175 watt bulbs with the 150 watts?

There are some ballasts that are made for 150/175 but usually the clip is different.

Are they electronic or PFO and what is the name of the ballast?

I'm going to move this to the general hardware/equipment section.
