Global Greenhouse 750 Watt 240 Volt Digital Electronic Ballast

- Global Greenhouse Lighting Digital Ballasts are top of the line electronic ballasts that fire both Metal Halide and High Pressure Sodium bulbs! These blissfully silent ballasts are highly efficient, producing very little heat. All of this while firing the bulb brighter, giving 15% to 20% more lumen output than a standard electro-magnetic core ballast. All of this because the ballasts fire at a higher frequency, minimizing the wear and increasing lamp life, 3 to 4 times.
