ELECTRIC CHRISTMAS LIGHTS
1946-1950
After the War
page 4

1949 was a pivotal year for NOMA. Shortly after their success with the Bubble Lites, other companies almost immediately issued their own versions of the popular lights. Some companies, like Paramount, circumvented the patents by using oil in their tubes while others blatantly challenged the patent by using the same methylene chloride that NOMA used. When the issue finally reached the courts, NOMA lost and the market was suddenly wide open for all.  Sticking with their original success, NOMA reissued the famous "biscuit" style lights, in the slightly modernized box as pictured below, left. The little girl  staring in wonderment at the bubbling light had changed her dress from a early 40s style blue outfit with stripes to a much more timely solid green dress. Her eyes had also mysteriously changed  color from blue to green to match her new outfit.

To add to NOMA's troubles, one of their sets of bubble lights was accused of starting a fire, which tragically involved a fatality. NOMA and most other bubble light manufacturers immediately added a fire retardant chemical to their plastic. NOMA outfits that include this chemical are clearly and boldly marked with the UL approval information on the front cover of the box (see picture above, third from left). The chemical caused the premature breakdown of the plastic in the lights, making them useless within a few years. Lights showing this disintegration are shrunken and severely distorted (fourth picture from left), and are often found with a whitish coating that is often erroneously attributed to spray snow or heat damage. The lights illustrated above show the damage that was caused by the flame retardant. Note that since these lights are from 1949 and later, they do not contain the glass slug. After a few years, it was determined that the NOMA bubble light set was not the cause of the fire, and the chemical was no longer used in the manufacture of the lights. The picture to the far right is of an ad NOMA strategically placed in the 1949 edition of the Fire Engineering Magazine, explaining the use of the new chemical.

Another victim of the chemically-impregnated plastic, NOMA Sno-Flake Gems were sold in 1949-1951. Few examples of the lights themselves survive. Those that do will likely be showing signs of deterioration from the fire retardant additive.
