Metal Halide (MH) Bulb

No, this is a Metal Halide bulb specifically engineered for the vegetative stage. Its 7200K color temperature mimics the blue spectrum of natural daylight, which promotes tight internodal spacing and vigorous leaf growth, but you will need to switch to a High Pressure Sodium (HPS) bulb for the flowering phase.

Yes, this Xtrasun bulb is designed for broad compatibility and functions seamlessly with both magnetic and electronic ballasts. It is a versatile choice if you are unsure of your ballast type or plan to upgrade your system later.

The 7200K rating provides a 'cool' blue spectrum that is ideal for vegetative growth. This spectrum helps prevent plants from stretching, resulting in shorter, bushier, and healthier plants before they enter the flowering cycle.

Yes, always handle the glass with a clean, dry cloth or gloves. Oils from your skin can create hot spots on the quartz glass when the bulb heats up, which significantly reduces the lifespan of the lamp and can even cause it to shatter.

For optimal performance, you should replace this bulb every 9 to 12 months of consistent use. Even if the bulb still turns on, the spectral output and intensity degrade over time, which can negatively impact your plant's growth rate.
