Simply slide this unique product over a mogul base socket on most horizontal burning reflectors to filter and disperse the intense hot spot of light directly under an HID lamp. With the hot spot diffused, you can hang reflectors closer to the plant canopy while reducing the risk of burning the plants directly under the lamp. The revolutionary shape, size and hole patterns were designed using the latest lighting development software. The Equalizer? will aid in improving the uniformity of your fixture by reducing the hot spot below the lamp. Made of 95% reflective German aluminum. US Patent: D583,092.
