eBay find, it is NOS. It has a sleeve too but not in the best of shape. I lit this on a 250w mercury HX type ballast and it has a neon-argon penning gas mixture. Took several minutes to reach full brightness and it has a pinkish orange color appearance, unlike the Norelco SON-H lamp which has a more yellowish color at full brightness. The starting set up is unique in the GE compared to those made by Westinghouse, Sylvania and Philips-Norelco. In the others, a bimetallic switch opens when sufficiently heated, in the GE lamp the bimetallic clip that touches the arc tube directly bends away from the arc tube when heated. I found the bimetallic switch was made by Texas Instruments and it is a Tri-flex E5.
