The Greenfingers 400W electronic ballast is suitable for use with both 400W High Pressure Sodium (HPS) and Metal Halide (MH) bulbs. It has a 4-phase manual dimming that can help to prolong the lamp lifespan by at least 10% with up to 30% energy savings compared with magnetic ballasts. It also features several protective functions including short circuit, circuit, overheat and lamp failure protection. The bat wing reflector spreads and directs the light in a downward focus to cover small to medium-sized plant growth areas. The compatible wattage HPS grow bulb can be used outdoors or indoors and as a thick glass housing for extra durability, enhanced wavelengths and lumen output power. The bulb is ideal for blooming and flowering and mainly produces a red spectrum that is perfect for germinating, flowering, and fruiting stages. Likewise the MH grow bulb is also ideal for blooming and growing stages and produces a blue spectrum that is perfect for all plant growth. The grow light can be hung in vertical or horizontal positions. The lamp does not flicker and works quietly and effectively. A pair of reflector yoyos is included to secure the reflector quickly and easily. The yoyos are made of a special composite material that is rust-proof and heat and cold-resistant.
