This 400W hydroponics lighting system represents the best value grow light. Its advanced electronic ballast supports both High Pressure Sodium (HPS) and Metal Halide (MH) bulbs, giving the grower the flexibility to choose the best selection 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.

Electronic ballast (400W)
Includes one High Pressure Sodium (HPS) bulb (400W) and one Metal Halide (MH) bulb (400W)
Electronic ballast truly supports both High Pressure Sodium (HPS) and Metal Halide (MH) bulbs (conversion bulbs not required)
Electronic ballast is UL-listed, CE certified
Two-year manufacture warranty on electronic ballast
Light reflector

- Fast startup - reaches full brightness in less than 1/4 the time of most magnetic ballasts.
- Completely silent - no more of the humming and buzzing.
- Small, compact design - most electronic models weigh less than 10 pounds compared to 44 pounds for magnetic ballasts.
- Longer bulb life - lumen output loss over time is dramatically less than with magnetic ballasts.
- Electronic ballasts can light both MH and HPS lamps
- More lumen output - up to 20% more lumen output than regular ballasts.
- Heat sink technology - no fans to break down and make noise; fan-cooled ballasts have a high failure rate.
