LEDwholesalers GYO2004 4-Piece 600 Watt Hydroponic Reflector Grow Light Set

This 600W hydroponics lighting system represents the best value grow light. Its advanced integrated 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. Reasons to Choose Digital Electronic Ballast: ? 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 ballats ? Electronic ballast lights 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 higher failure rate Features: ?
