The Super-Spreader combines common sense and innovation with advancements in effective surface technology to produce a truly Super Light Spreader! The new design is attractive, lightweight and easy to install. The 'Spreader Heads' are made from 97% reflective glass-coated aluminum with a prismatic micro-textured surface. This incredible alloy is super cool, very reflective and creates even light distribution. The prismatic surface reflects and redirects light in a selective 4-way pattern for incredible results! How & Why They Work! The design of the Super Spreader is based on logic and simplicity. All horizontal reflectors create an over hot, over bright spot directly beneath the lamp. The Super-Spreader spreads the excess light and heat proportionally to all areas of the grow room (especially the corners and edges which are often underlit). This creates even light and more harmonious growing conditions throughout the entire grow room.
