Par Pro Hyper Arc High Pressure Sodium Lamp, 1100 Watt, 2000K

The Par Pro 1100 Watt Hyper Arc High Pressure Sodium (HPS) bulb delivers a massive 2,380 µmol on the Galaxy 1000 Watt turbo setting. The Par Pro Hyper Arc lamp provides the perfect 2000° K temperature for maximum fruiting and flowering. This bulb exceeds all micromole levels currently offered in the lighting industry. 

Long life, reliability and high efficacy (over 150 LPW) makes this bulb an excellent choice for indoor horticulture applications. These bulbs are not meant to be operated on low frequency (< 70 kHz/70,000 Hz) electronic ballasts. Rather, they are intended to operate only with high frequency electronic lighting ballasts, such as Sun System 1 or Galaxy. Maximum lighting output is achieved on the Turbo setting and will also operate on Hard Core or Hard Core DE magnetic ballasts.
