150 and
250 watt double ended HQI metal halide lamp. A bright mix
of blue and white light producing a crisp ice blue color.
This bulb is brighter than their 20K double ended bulb counterparts
and is a great choice for reef tanks. This bulb will bring
out fluorescence in corals & fish well. Must be used with
a 150W or 250W HQI ballast or 150W or 250W electronic ballast.
