SunPulse Pulse Start Metal Halide Grow lamps were created by the GAS Technologies group of photo-biologists, plant scientists, mechanical and electrical engineers, gas chemists, and HID lamp designers. They are designed with true solar symmetry for true photochemical reactions in living organisms, greater molecular efficiency in operations, and better color rendering. Sun Pulse lamps are made with the highest quality and quality control.

* Available in Kelvin ratings of 3k, 4k, 6.4k, & 10k

* Designed to work with certified electronic and digital electronic ballasts

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.
