The Thallium-Mercury HID Lamp

The Thallium-Mercury HID Lamp - a Light Source for Light Communities and Areas of Light

Depiction of a possible appearance of
the Thallium-Mercury HID lamp

According to Dr. Larson the light was predominately green. During an interview conducted when I collected this experimental lamp, he noted: "I thought it would be a great lamp for lighting in the parks and stuff like that because it was 85 lumens per watt, and green."
 ~ Hal Wallace ~

"In 1941, Schnetzler made a mercury-thallium lamp having an efficiency of 70 lm/W, almost twice as high as its mercury counterpart. The desired thallium vapor pressure was reached by operating the arc tube at thrice its normal power loading, with the consequence we can imagine on the life expectancy."

The pure Argon HID lamp, an expectable source of 'electric blue light' for esoteric purposes

The pure argon HID lamp, an expectable source of 'electric blue light' for esoteric purposes.

If you are an average 'awakened' specialist,... consider it this way.

You have a well known nowadays 'mercury lamp' (uncoated) with more amount of argon filling in the discharge tube, but with no (or very, very less) mercury.
As usual, the discharge will well start in argon only.

The research has to bring out which has to be the amount of argon (with no mercury) in order the discharge to reach the nominal current (i.e. 1.50amps for a 175W lamp), connected to a correspondent 'mercury ballast' (i.e. the 175W mercury ballast)...

This is the step for the proper working of the discharge, the electrodes and the ballast...

The next steps... is... 'the show',... for both researchment and results as well... :-)

How it may look like, would you find in this page:

Depiction of a possible appearance of the 
pure Argon Medium Pressure lamps

In case the research seeks to develop a medium pressure discharge (instead of a high pressure one) and are we using oversized arc tubes (as in depictions above) the electrodes need to be not oversized too, but instead, electrodes have to be corresponding to the wattage we intend to achieve, in order to reach the needed heat for emission.

What we call here 'medium pressure discharge' goes into discussion in the case, if due to research, the high pressure pure argon lamp in not achievable regarding certain technical inconveniences or if the output spectrum is too much different from what we desire to achieve.

Xenon HID Lamp with Synthetic Gemstone 'Protection Tube'


LIGHTS for ESOTERIC purposes:
>A HID xenon bulb with a 'protection tube' made of synthetic gemstones.

>>The TACHIONIZED HID xenon bulb with synthetic gemstones.
          i.e.: Synthetic Emerald, Synthetic Aquamarine, a.o.

If you are a specialist, consider it in a shape of ED(BT)28(90) or ED(BT)37(120) HID ‘protected metal halide lamp’ (thus it might even be, or rather not, a metal halide lamp).

It is more desirable to be rather a xenon HID lamp (similar in shape and appearance of a ‘protected metal halide lamp’), due to its more day-light spectrum of light, than that of the 6500K (‘day-light’) metal halide lamps.

Consider also that instead the ‘metal halide’ arc-tube you have a xenon discharge arc-tube.

And, instead of the protection tube of the ‘protected metal halide lamp’, you have a ‘synthetic gem’ tube, but not for the protection (explosion proof) of the arc tube, but instead, to pass the ‘day light’ of the xenon discharge through the synthetic gem tube, (which should have most as possible of the original gem properties).

Details to come on the blog.

Till then, just imagine it...

How it might look alike: 
Metal halide lamp bulb (type /O with arc tube shield):

> Instead the ‘metal halide’ arc-tube you have a xenon discharge arc-tube, which gives an almost day-light white spectrum.

> Instead of the protection tube of the ‘protected metal halide lamp’, you have a ‘synthetic gem’ tube, which allows the ‘day light’ of the xenon discharge to pass through the synthetic gem tube.
