A cool tube reflector is a variation of an air-cooled reflector that takes up less room so it can still contain heat but will fit in smaller spaces. It's the most effective type of hood for reflecting light down to your plants, prevent heat stress by containing heat near the bulb so you are able to keep lights closer to plants for increased light levels and can be easily hooked up to an exhaust system or a carbon filter via ducting. Ideal for grow tents as they have been specifically designed to work together.
