The sodium light with its superior long-wavelength light and lumen-per-watt performance is best suited for plants 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 plants can fit under a 4' x 4' (16 sq. ft.) area? A: The amount of plants that can fit in a 4' x 4' area is completely dependent on the size of the plants 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.
