SUPER SPREADER Medium 400-600 Watt HPS Sunlight Supply Co Light Spreader 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 95% 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. NOTE: By attaching the Super-Spreader® accessory, the Adjust-A-Wings® performance may be enhanced significantly. Adjust-A-Wings® fitted with Super-Spreader® can be lowered to an unprecedented 10″-12″ from growing plants to produce awesome growing power while maintaining maximum area coverage and minimum heat build-up. Yield increases of up to 50% are not uncommon with proper use of this truly outstanding product. Fast And Free Shipping.
