21) When adjusting HB3 9005 bulb and the case of direct eye contact with the open HB3 9005 bulb, always wear safety UV glasses. 22) Damage, soiling and fingerprints should be avoided and removed with alcohol before HB3 9005 bulb is switched on. 23) The ballast will produce very high voltages on switching on HB3 9005 bulb and during operation. A deuterium arc lamp (or simply deuterium lamp) is a low-pressure gas-discharge light source often used in spectroscopy when a continuous spectrum in the ultraviolet region is needed.
Plasma "arc" or discharge lamps using hydrogen are notable for their high output in the ultraviolet, with comparatively little output in the visible and infrared.
Emission spectrum of an ultraviolet deuterium arc lamp showing characteristic hydrogen Balmer lines (sharp peaks at 486 nm and 656 nm labeled D? and D? from left to right respectively), continuum emission in the ~160-400 nm region and Fulcher band emission between around 560 to 640 nm.
A deuterium lamp uses a tungsten filament and anode placed on opposite sides of a nickel box structure designed to produce the best output spectrum.
The arc created excites the molecular deuterium contained within the bulb to a higher energy state. The spectral line structure of deuterium does not differ noticeably from that of light hydrogen, but deuterium has a slightly stronger molecular bond (439.5 vs.
Because the lamp operates at high temperatures, normal glass housings cannot be used for a casing.


The typical lifetime of a deuterium lamp is approximately 2000 hours (Most manufacturers guarantee 2000 hours, but newer lamps are consistently performing well out to 5000 hours and more). Due to the high intensity of UV radiation emitted by the bulb, eye protection is suggested when using a deuterium bulb. No flickering, no infrared light or ultra-violet light, no RF interference ,harmless to human body. With identical dimension to traditional spotlight, can be installed in the ordinary compatible socket.
Once your order is shipped, you will be emailed the tracking information for your order’s shipment. When handling HB3 9005 bulb the necessary safety precautions should be taken on account of the high pressure(i.e. So contact with HB3 9005 bulb and wires should be avoided and a safe distance of at 30mm should be maintained. The emission spectrum of deuterium differs slightly from that of protium due to the influence of hyperfine interactions, though these effects alter the wavelength of the lines by mere fractions of a nanometer and are too fine to be discerned by the spectrometer used here. Care must also be taken to avoid touching the bulb directly to avoid burns due to high operating temperatures.

Arc lamps made with ordinary light-hydrogen (hydrogen-1) provide a very similar UV spectrum to deuterium, and have been used in UV spectroscopes.


Deuterium is used rather than hydrogen because of its greater intensity of UV emission in the molecular band. The decrease in the plot is due to decreased efficiency at low wavelengths of the photo detector used to measure the lamp intensity.
Touching the bulb directly even when cool can smudge the casing and therefore reduce output intensity.
However, lamps using deuterium have a longer life span and an emissivity (intensity) at the far end of their UV range which is three to fives times that of an ordinary hydrogen arc bulb, at the same temperature. Because the filament must be very hot before it can operate, it is heated for approximately twenty seconds before use. This process is not the same as the process of decay of atomic excited states (atomic emission), where electrons are excited and then emit radiation.
Deuterium Lamp's continuous spectrum is useful as both a reference in UV radiometric work and to generate a signal in various photometric devices. Deuterium arc lamps, therefore, despite being several times more expensive, are considered a superior light source to light-hydrogen arc lamps, for the shortwave UV range.
Because the discharge process produces its own heat, the heater is turned down after discharge begins. Instead, a molecular emission process, where radiative decay of excited states in molecular deuterium (D2), causes the effect.
