| 
| 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 plants in the flowering stage. -
Best for big blooms and radiant flowers |  
| Â 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.
