250w MH Universal Bulb

M.H. bulbs are white/blue in the spectrum. They are the best lamps available for vegetative growth of indoor plants. This type of light spectrum promotes short, compact growth in plants. They are ideal for indoor greenhouses and commercial growing applications. M.H. bulbs emulate bright summer sunlight. To plants, this means quality simulated sunlight and a high photosynthesis level. These bulbs are universal, meaning they can be burned in any position, vertical or horizontal.100 watt:Initial Lumens: 9,000Socket: StandardOperating Position: Universal175 watt:Initial Lumens: 13,000Socket: StandardOperating position: Universal250 watt:Initial Lumens: 22,000Socket: MogulOperating position: Universal400 watt:Initial Lumens: 40,000Socket: MogulOperating position: Universal1000 watt:Initial Lumens: 110,000Socket: MogulOperating position: Universal
