Our Xtrasun Metal Halide (MH) Conversion lamps allow you to switch to a Metal Halide (MH) lamp without needing to switch to an MH ballast. Conversion lamps are very convenient options when your space for other types of ballasts and fixtures is limited. These conversion lamps are engineered specifically for use with both magnetic and electronic ballasts, and with their 7200° Kelvin color temperature they consistently provide intense light in the correct spectral range for energetic vegetative growth. Xtrasun lamps offer exceptional performance and feature high quality components.

*Correlated color temperatures will fluctuate pending which bulb is purchased.

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 lamps with lower Kelvin temperatures for fruiting/blooming/flowering and lamps with higher Kelvin temperatures for vegetative growth.

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 provide to the plants will have significantly degraded after this time of continuous use. (NOTE: The above does not apply to LED lamps, which have much longer service lives).

Does the Mondo reflector have attached flanges and a lens system?

The Mondo Reflector has louvered flange covers that must be removed in order to attach the included 6" flanges. A lens system is included with the packaging as well to complete the air-cooling functionality.

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.
