Know before you buy
This is a Metal Halide bulb specifically engineered for the vegetative stage. Its spectral output is tuned to promote dense, robust growth rather than flowering.
The BT-37 refers to the bulb's physical shape and size. You should ensure your reflector or hood is compatible with this larger, tubular bulb dimensions to avoid clearance issues.
Yes, this 1000-watt Metal Halide lamp requires a compatible 1000-watt ballast. Always check that your ballast is rated for Metal Halide technology to ensure safe operation and proper ignition.
This lamp is designed for high maintained lumen output, meaning it retains its intensity longer than standard bulbs. However, like all Metal Halide lamps, you will see a gradual decrease in spectral quality, so it is recommended to replace it after a certain number of grow cycles.
The B/U designation indicates that this bulb is designed for Base Up operation. For optimal performance and longevity, it should be installed in a vertical position with the base facing upward.
