The 64623 Halogen Bulb is sometimes referred to as "HLX 64623" which means that the bulb has Zenophot gas which replaces the krypton gas that is normally in most halogen light bulbs. This is considered by many customers to produce brighter light. The HLX identifies lamps that employ XENOPHOT technology, an innovation first introduced by OSRAM. In XENOPHOT lamps, krypton - the normal fill gas used in halogen lamps - is replaced with xenon gas. The xenon reduces the rate of tungsten vaporization and allows for a higher filament temperature. Depending on the application, XENOPHOT can either improve luminous efficacy or can extend the lamps service life. The ANSI (American National Institute of Standards)code for this light bulb is (EVA) and can be bought by many microscope dealers globally.
