Hydrogen and deuterium lamps for UV vary in the gases that are utilized in the discharge.. Deuterium lamps also generate a higher intensity radiation compared to hydrogen lamps.

Deuterium: 1 proton, 1 neutron
Tritium: 1 proton, 2 neutrons
Duritium is an name error; you think probably to deuterium.

Difference between tungsten lamps and carbon lamps?
tungsten lamp has got inert gas argonsometimes iodine is added to improve intensity carbon filament produces less light than tungsten lamp but it radiates much less energy in the form of heat waves
7 Why does a deuterium lamp produce a continuous rather than a line spectrum in the UV?
To answer this question, let's think about the excitation and relaxation processes involved. In the excitation process inside a deuterium lamp, an electrical arc between an oxide coated filament and an electrode excites D2 to D2*. Next, the D2* dissociates into individual D atoms. Let's call these D' and D''. Also, a photon of light is released. For an individual event, the total energy posssessed by D2* is apportioned between the kinetic energies of D', D'', and the photon. The sum of the kinetic energies of D' and D'' can vary from almost zero to the original energy of D2*. If the kinetic energies of D' and D'' are relatively small, the energy of the photon is large, and a shorter wavelength of light is emitted. If the kinetic energies of D' and D'' are relatively large, the energy of the photon is small, and a longer wavelenght of light is emitted. In a population of D2*, a distribution of kinetic energies of D' and D'' will result, allowing for a continuum spectrum to be emitted from the lamp.
What is the difference between a metal halide lamp and a halogen lamp?
A halogen bulb is a traditional tungsten filament bulb filled with a noble gas that gives off a soft, yellowish light. In a metal halide bulb, the light emitted is bright white or even bluish. They have a longer life than halogen bulbs, but their brightness can diminish over time.
What will happen if mercury lamp is used instead of sodium lamp in plane diffraction grating exp?
for diffraction grating mercury lamp is used not sodium lamp.
What is inside a lava lamp?
Inside a lava lamp there is wax.
What is the difference between a pole lamp and a normal lamp?
The difference between a pole lamp and a normal lamp is very miniscule. A pole lamp stands on a pole and the lights are strung up like they are on a tree.
What is the difference between lamp and torch?
a lamp uses electricity and a light bulb, a torch is fire
What is difference between bulb and lamp?
Words are used interchangeably.
What is the difference between compact fluorescent lamp and fluorescent lamp?
well one is spelled differently than the other
Difference between a lamp and a bulb?
Lamp have required high rating to glow & have a specific luminus area.exa-table lamp,florucent lamp,sodium vapur lamp,BUT but bulb have no required rating exa- halogin bulb
Is hydrogen light a monochromatic source?
NO. It produces four lines with wide difference in wavelengths. So it is not a monochromatic just as sodium vapour lamp
What is the difference between 2 pin and 4 pin PL lamp?
one has more pins
What is difference between R40 and BR40 light bulbs?
R40 is a Red Heat Lamp Light Bulb BR40 is a Clear Heat Lamp Light Bulb
What is the difference between MR11 and MR16 lamp fittings?
An MR-11 is about half the size if an MR-16.

d. incandescent lamp
What is the difference between 35 watt and 50 watt h.i.d. lights?
15W, asuming that you are talking about the same type of lamp.
What is a bulb base?
what is the differance between a medium base buld and a standard base bulb?No difference. They are one and the same. They are regular household type bulbs.
