7H198K  The Lumalarm

Pleasant glow all night long!  The electric alarm clock with the illuminated edge-lit dial!  This G-E Lumalarm casts a soft, pleasant glow all night long, chases gloom.  Its gentle alarm wakes you pleasantly.  Note the beautiful ivory-plastic case and its smart modern design.  G-E Clocks are so inexpensive you'll want one for every room.  Wonderful gift idea too!  Remember, too, these wonderful advantages: 1. No winding.  2. Quiet.  3. Dependable.  4. Accurate.

That's my Lumalarm  above.  Possibly my favorite clock from this whole era.  This one takes an NE-2H small, neon lamp (120v, 1.9mA) and a 30K ohm resistor.

from the Wilmington (Ohio) News Journal 1955 We don't have sales figures for the 7H198K but I don't think it was still available in 1955 (excepting maybe at Hyer's).
