Hongruilite Double Ended 600W/1000W HPS/MH 120V/240V Grow Light Reflectors (NO Bulb) for Digital Dimmable System Hydroponics Indoor Growing Plants UL/ETL Listed (DE Open Hood Plus)

Completely impressed by the quality of this reflector at half the price of the popular brands! Open hood is an advantage over air cooled, as the air passing over the lamp cools the arc tube and drops spectra emissions by 13%-15%! Glass between plants and lamp also decreases spectra emission by another %10, so no glass to filter out specrta emission is completely awesome! That's a total of nearly 25% loss of PAR energy just by using a closed air cooled hood! The shape and design of the square reflector provides a more even footprint of light in a 4'x4' with a 600W lamp, and an 8'x8' footprint with a 1000W lamp. Anything else is a waist.

Put this together with growers choice de630 cmh absolutely great quality hood
