Inventor Prototype GE "Electronic Halarc" Residential Metal Halide Lightbulb!

Offering for your consideration an early clear / see-through prototype of one of the first Halarc residential metal halide light bulbs developed by General Electric for residential use. The concept of the Halarc was in response to the 1970s energy crisis and was truly ahead of its time and is the early forerunner of a variety of more energy efficient lightbulbs such as CFLs.
The top half of the lamp is glass and the bottom half seems to be a type of thick plastic or plexiglass type material. The electronic components are clearly visible inside. The lamp is contained in its original white unmarked box and blister pack. It has been in climate controlled storage ever since it's been in my family, and was never removed from the packaging other than to photograph it for this listing and to test it to verify that it does work (see detailed photos). My Father worked for GE's Lighting Division and was given the prototype by a member of the Research & Development team in approximately 1979.
Here's a history of the development of the Halarc lamp in the 1970s and early 1980s, from the Smithsonian Institution:

At the time of the energy crisis of 1973, the metal halide lamp was being used successfully for outdoor lighting. Experiments with miniature metal halide lamps had been conducted by GE engineer (and tungsten halogen co-inventor)

There were technical problems in making a residential metal halide lamp, some of which were due to basic limitations of physics. The lamp had a warm-up time of about three minutes, could only be used in an upright position, and did not produce a full, continuous spectrum like an incandescent lamp. As a result colors appeared slightly different under this light. But by 1980 GE had a lamp that achieved about 40 lumens per watt, double the energy efficiency of regular incandescent lamps.

GE introduced the "Electronic Halarc" lamp in 1981 to great fanfare. But consumers found the limitations of metal halide technology unacceptable, and also balked at the cost: about $15 (that would be about $30 today). Equally important, public concern about conserving energy had abated. For those still interested, an alternative product, compact fluorescent lamps, had by then reached the market. Despite the millions of dollars GE spent on promotion, the lamp was no longer available in 1984.
