Pure Light MH Grow Bulb for Indoor Vegetative Cultivation

Pure Light MH Grow Bulb, 250-400-600W. The Pure Light MH Grow lamp for Vegetative Growth is a high-pressure metal halide lamp, specifically developed to be ideal for the vegetative growth phase of crops. The Pure Light MH Grow lamp for Vegetative Growth offers an excellent balance of price, quality, and efficiency. Thanks to their compact size, various shapes, wattages, and available color temperatures, their high luminous efficiency ranging between 80 and 100 lumens/watt, their high color rendering index (CRI) of 80-90 (and up to 95 in "D" (Daylight) tones with a 5600 Kelvin rating), and their long lifespan (up to 12,000 hours), they have become some of the most widely used lamps in indoor cultivation today. 250W Technical Specifications:

The inrush current of MH-HPS–AGRO lamps can be more than 90% higher than the steady-state value, especially if these lamps are powered by electromagnetic ballasts. The MH Grow lamp for Vegetative Growth is a discharge bulb type based on light emission through luminescence from an ionized gas. Gas ionization is achieved by means of a potential difference, which causes free electrons and positive ions to migrate to the different ends of the lamp (where the electrodes are located).

The discharge lamp is a type of arc lamp.

The luminous efficiency is high (up to 150 lumens/watt in the latest high-efficiency Super versions) and the lifespan is long (over 16,000 hours). Specific construction features address the chemical aggressiveness of sodium. In the event of a power interruption, unless using special ballasts capable of generating 30-70 kV voltages, the lamp requires a 3-5 minute cooling cycle. At the end of their life, due to the depletion of sodium in the tube, these lamps become unstable during operation, causing the phenomenon of sudden switching on and off until they are no longer able to restart.
