This German-made ushio 20,000K+ metal halide bulb offers excellent coloration and intensity. Crisp blue/white appearance, full spectrum - the combination of different wavelengths produce different colors in the spectrum and appear to the naked eye as crisp blue/white light. Use alone or add actinic for a bluer effect. This bulb has a heavy concentration wavelength spike in the 420 and 460Nm (nanometer) range with additional concentration spikes in the 380Nm, 550Nm and 580Nm wavelengths. Tested in Germany, simulates natural daylight as in the ocean at depths up to 13 feet. Longer life 20,000K+ metal halide has an exceptionally high rated life. Very high color rendering Index of 95 CRI. This is a probe-start bulb, but it will also work with a magnetic pulse-start ballast, magnetic hqi ballast or electronic ballast.
