400 watt advanced electronic ballast supports both High Pressure Sodium (HPS) and Metal Halide (MH) bulbs, giving the grower the flexibility to choose the best selection of light simply by changing the bulb, instead of having to own two separate light systems.  MH is used for accelerated vegetative growth, then switch to HPS to encourage flowering, fruiting and budding.

Features:

• 400W
• Works with both High Pressure Sodium (HPS) and Metal Halide (MH) bulbs
• Automatically detects type of bulb installed and adjusts itself accordingly
• UL-listed, CE certified
• One-year manufacturer warranty
• Discreet packaging

Advantages:

• Fast startup - reaches full brightness in less than 1/4 the time of most magnetic ballasts.
• Completely silent - no more humming and buzzing.
• Small, compact design 
• Longer bulb life - lumen output loss over time is dramatically less than with magnetic ballasts.
• Electronic ballasts can light both MH and HPS lamps.
• Heat sink technology - no fans to break down and make noise; fan-cooled ballasts have a high failure rate.
