Sunmaster Dual Spectrum Sodium Bulb 600w

The Sunmaster Dual Spectrum high pressure sodium lamp has been developed specifically for horticultural use. It has an enhanced blue spectrum, making it ideal for use during growth and flowering. 

While most standard High Pressure Sodium lamps emit light that is mostly towards the yellow-orange range of the light spectrum (Powerplant Super HPS), this Sunmaster Dual Spectrum Lamp produces a mixed spectrum specifically for horticultural use.

This lamp has an enhanced amount of blue light between 400nm and 550nm. This encourages vegetative growth and aids in the development of young plants.

Although it’s still not as good as using a separate Metal Halide Lamp for vegetative growth, the Sunmaster Dual Spectrum Lamp provides a good middle ground for use throughout vegetative growth and flowering.

Producing 90000 lumens, the Sunmaster Dual Spectrum Lamp is very high quality with consistently high output.

Average life: 10000 hours.

To maintain a high lumen output we recommend you change your lamps every 9-12 months.
