The Deep Blue Star 20,000K metal halide lamp will be available for 250W SE, 250W DE, and 400w SE (mogul) base.  This lamp is designed to fire on any electronic ballast and will fire on most magnetic ballasts, although Neuco recommends the use of electronic ballasts to insure color temperature and operating life span.

The timing of this announcement is particularly interesting for 20,000K MH users because recent reports suggest Radiums may be in short supply due to recent enforcement of import regulations pertaining to mercury content within HID lamps.

CoralVue is the exclusive North America dealer of Neuco Germany, makers of the AquaConnect metal halide lamps.
