Winged Reflectors have open adjustable wings to help conform the light footprint to your grow area size, often made out of pliable aluminum. The glass in traditional air-cooled reflectors reduces light intensity by approximately 8%. Open wing reflectors allow you to get the most out of your light source to your canopy of plants. To cool your growing environment when using these lights, cool the environment not the fixture directly--use inline fans for exhaust and/or an air conditioning unit.
