Product Description ------------------- iPower MH bulbs make your s grow better & faster metal halide lamp for growth product Description Item specificsitem type: grow lights width: 3 cmpower source: achid: metal halide lamps body material: Glass base material: aluminum light source: halogen bulbs is dimmable: Yes Brand name: iPower power: 400W/ 600W/ 1000W optional length: 27 5cm voltage: 85-265v features: growth application: outdoor, professionaladvantages: the maximum blue light for vegetable growing strong；more pure white light than the popular HPS lamps, close to daylight frequencies, which allows it to be used for growing sbalanced orange-red light for stem elongation & flowering day light provide optimal spectral energy required for vegetative growth high ratio of red & blue spectral for a good photosynthetic efficiency good Lm output for a high nominal value robust s with high blue light output high ratio of red light to y growth long average life, high Lm output, low energy consumption for indoor (high ceiling areas - ""high bay"" Applications) & outdoor use due to good light quality application: efficient lighting growing in the greenhouse extend the additional lighting culture exterior a ID for growing s, horticulture & hydroponics industry" .com ---- iPower Grow Light ----------------- iPower Digital Dimmable Grow Light Ballast - 400W, 600W, 1000W -------------------------------------------------------------- Want to grow bigger and better s? Tired of yielding less due to poor weather? iPower HPS/MH Digital Dimmable Grow Light System is the solution for all indoor & greenhouse gardens. iPower Super HPS & Metal Halide Lamp - 400W, 600W, 1000W ------------------------------------------------------------ Super High-Pressure Sodium Bulb * produces light by an electric arc through the sodium mixture within the filament. * The sodium light with its superior long-wavelength light and lumen-per-watt performance is best suited for s in the flowering stage. * Best for big blooms and radiant flowers Metal Halide Bulb * produces light by an electric arc through the vaporized mercury and metal halides, a mix of metals and halogens. * The filament generates a wider spectrum of wavelengths of light, produces more short-wavelength light and has strong light penetration. * Best for optimized vegetative growth Frequently Asked Questions -------------------------- Q: How many s can fit under a 4' x 4' (16 sq. ft.) area? A: The a of s that can fit in a 4' x 4' area is completely dependent on the size of the s and the size of the pots used. A five gallon pot is about 12" in diameter on the bottom, which means you may have up to 16 pots in a 4' x 4' area. Q: Can a lower wattage lamp be used with a higher wattage iPower ballast, and vice-versa? A: Different mismatched wattage lamp and ballast per light fixture may cause premature ballast and/or lamp failure, and is not covered under warranty. Please use the same paired wattage lamp and ballast per light fixture; the dimming feature is designed for the purpose of a lowering lamp output when needed.
