Sunmaster Lighting Systems for Greater Yields

Blue Ice 5500K
• Stronger blue component for maximum vegetative growth

Developed by distinguished physicists and leading agricultural researchers, the SUNMASTER line has been built on the marvelous versatility and flexibility of metal halide technology. By blending specific halides in the arc tubes, they have created lamps which offer significantly more usable light energy for hydroponics and horticultural gardening.

Moreover, each SUNMASTER lamp has been customized to meet the diverse nutrition requirements of plants at various stages of their growth cycles. So, while the sun may come and go, SUNMASTER lamps are sure to consistently provide new levels of quality and productivity. If not the sun... SUNMASTER

All Sunmaster® lamps are enhanced for superior operation on high frequency digital ballasts. Each electrode in the lamp uses a special blend of Nickel (Ni 65%) and Copper (Cu 30%). With Sunmaster's spectral families, each lamp is tailored to promote optimum development at each plant growth stage.

Which lamps are recommended for use with the Phantom and Xtrasun digital ballasts?

Most lamp brands distributed by Hydrofarm are approved for use in the our digital ballasts. Sun Pulse and Plantmax lamps are the preferred lamp brands for use with the Phantoms and Xtrasuns. NOTE: Many "blue", "super blue", or dual arc tube bulbs will work intermittently with Phantoms. Try to avoid using these bulbs with our digital ballasts.

My new bulb isn't lighting up, or only lights up sometimes. How can I fix this problem?

The problem might be a bad connection in the mogul socket. Make sure to disconnect the unit from the power supply, and then look inside the mogul socket for a metal tab. Pry this tab upwards a little bit to make better contact with the bulb base.

What is the importance of color temperature ratings (Kelvin) on bulbs? i.e(3K, 6.4K, etc.)

Kelvin is a unit of measure that rates color temperature of a light source. Lower Kelvin temperatures will display deeper hues of red and orange light. Higher Kelvin temperatures emit deeper concentrations of blue light. The difference of each stimulates growth in plants depending on the phase of production. Ex. use lower K for fruiting/blooming/flowering and higher K for leaf/chlorophyll production.

How often should I replace my grow bulbs?

Whether fluorescent, sodium, or halide, we recommend to replace light system bulbs every 1 to 1.5 years if ran for a minimum of 12 hours per day. Although they may still ignite for multiple years, quality of light to the plants has degraded after this time of continuous use.
