Hoods & Reflectors

Single Ended Bulb Grow Light Reflector Types
Grow Light Reflectors

There are many shapes and sizes of HID light reflectors available and each produces a different light footprint and other benefits. "Air-Cooled" and "Cool Tube" reflectors allow you to run ducting and pump air over the bulb to help with the removal of heat from your grow room and are typically sealed with glass. "Open" reflectors come in various shapes such as "wing," parabolic, and rectangular. Double-Ended HID Lights require compatible reflectors. HID lighting can also be run without a reflector by mounting the bulb and socket directly from the ceiling of a grow room, or hanging them.

Reflectors and lighting technology are constantly improving and a small increase in efficiency can pay for itself tenfold over the course of a year or two. But does it really make a difference what you spend? The short answer is yes, in the right situation. Your grow room is like any other system—it’s a chain that is only as strong as its weakest link. If temperature, humidity, CO2, nutrient strength, pH and watering frequency are all dialed in, then optimizing photosynthetically active radiation (PAR) will correspond with an increased yield and a better quality product. However, if you buy the most expensive lighting system on the market, but don’t give your plants the resources they need you will end up with small yields of low-quality product. Many factors determine how PAR is distributed over an indoor canopy: grow lights, the type of ballast and reflector, spacing between lights, and distance from the canopy.
