What is the importance of color temperature ratings (Kelvin) on bulbs (3000K, 6400K, 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. As a general rule, one should use

How often should I replace my grow bulbs?

Whether fluorescent, sodium, or halide, we recommend replacing light system lamps (bulbs) every 1 to 1.5 years if operated for a minimum of 12 hours per day. Although lamps older than this might still ignite for multiple years, the quality of light they p

What is a Mogul base(E39) socket?

The Mogul base (E39) socket, has a larger diameter and are primarly used in larger lamp wattages. The designation E39 refers to the diameter of the light bulb screw base in millimeters, e.g. E39 has a diameter of 39mm.

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.
