250W 6500K MH BULB—IWASAKI

The Iwasaki 6500K metal halide bulb is a full-spectrum Daylight bulb. It offers excellent light intensity, but will be slight yellow-green in coloration. A great bulb to achieve fast growth. This bulb will work with a standard magnetic ballast, magnetic EYE ballast or electronic ballast.
