R.L.M.C. INTERIOR MEMORANDUM
Date
8/23/19
Subject
For Attention of
Mr. Dimick.
Answering Memo. of
Comparative Luminosity of 'Undark' and 'Luma', Continued.
Compare the prices of Lums and our materials with the same
or nearly the same luminosities, 8.8 for example Luma 5 and Undark F, both reading
21, the price of $13.25 in the one case and $6.00 in the other.
Column 3, Cost per Unit, affords many interesting comparisons
and points for study. This is valuable not only to point out the superiority of
Undark but also to point out the materiale the t afford the best value for the money,
ranging from "p" to "K" inclusive.
"L" is apparently somewhat out of line with other readings of
Undark.
This is due probably to some slight inconsistency of price and probably
in a measure also to the reading. It ie difficult to secure the same accuracy
reading low luminosity materials as when reading bigh luminosity materials.
Yours truly,
RADIUM LUMINOUS MATERIAL CORP.N,
