Digital Greenhouse Dimmable 400 Watt Ballast

The newest in digital technology, Digital Greenhouse Ballasts are brighter, more efficient, and lengthen lamp lifetime use. Lightweight, quiet, and low heat operation provide awesome value at an unbeatable price. Digital Greenhouse electronic ballasts are more efficient and reduce energy consumption while improving lighting quality and increases garden yields. They feature patented “soft-start” technology which increases lamp life and stops voltage spikes on your power meter. This soft-start technology allows for 50% less power consumption during lamp startup.

Dimmable Digital Electronic ballasts are the latest innovation in High Intensity Discharge (HID) horticultural lighting technology. The Digital Greenhouse Dimmable Digital Ballasts allows you to operate your 400 watt lamp at 50%, 75% or 100% Full Power! This is especially useful when you have young plants that do not need the full 400 watt output You can start your plants under 50% power, then as they grow move up to 75% and finish them off with 100% full power. This saves you money on your electric bill and, more importantly, fulfills the lighting needs your plants require at specific stages of growth. It’s all about control! You control the output of the light your plants need when they need it.

Digital Greenhouse electronic ballasts are lighter, smaller and more reliable than standard technology “core & coil” ballasts. It is also nearly silent, no noise or hum! The ballast is totally sealed, which protects the unit from dust and dirt, ensuring a lifetime of trouble-free operation.

Digital Greenhouse electronic ballasts operate at a high frequency (20,000hz) instead of the lowly 60hz of standard core & coil ballasts. This allows the lamp to operate more efficiently, produce more usable light for plants and last longer. Lamp lumen loss is minimized allowing for a brighter system over time and extending usable lamp life. The ballast will automatically adjust to any input voltage from 90 volts up to 260 volts. It comes equipped with a 10′ grounded power cord, and plugs into standard 120v household current. You can easily change voltage to 220 or 240 volts if you wish.

Digital Greenhouse ballasts are now UL listed! What does this mean? This means that Digital Greenhouse ballasts are now certified for safety by Underwriter Laboratories, the worlds leading electrical product safety organization. Check the other brands, are they listed, probably not. Demand safety, demand Digital Greenhouse.
