HPS 600w Hydrofarm ballast 120/240V Hydrofarm Sun System XT6AC Air-cooling reflector hood 6” duct Used (about 1 year) High pressure sodium (HPS) bulb. Kept just for testing. HPS light systems are more efficient, for basement grow rooms, compared to CFL & also LED! LED is more efficient if heat is an issue. You will get more height grow space if you use HPS compared to LED. Depending on your bulb, you can get more lumens than LED per square feet. Am selling because I have no central A/C and have heat issues.
