Browzing through old matter, I found a page from a 1963 magazine, the Farm Journal with some handy advices:
A couple of things jump out immediately. First, they had fluorescent light dimmers in 1963? For YEARS I’ve been seeing warnings on dimmer switches I’ve installed that they should never be used on a fluorescent light. Was this really a thing and, if so, what happened to them?
Second, were dimmers really that new in 1963? A dimmer is just a rheostat, which has existed as long as systematic study of electricity has, maybe longer. It’s just a wound coil of wire with a movable contact. In the case of a light dimmer switch, it is usually a circular affair. An industrial example may be seen here.
Another point, potentially hidden, is the price. 16 USD for a dimmer is outrageous today. They are about half that or less for a no-frills rotary dimmer switch, per Home Depot and Lowes. (I’m not linking to them because their websites change so regularly.) Using an economical adjustment for inflation, the highly recommended Measuring worth website, the purchasing power of 16 USD in 1963 is about 124 USD in 2014. That is by no means “inexpensive”, especially for farmers, who are notoriously not high earners.
Finally, the company in question, Hunt, appears to still be around, at least as a brand. It is owned by “Caribe Corporation”, which appears to just be an alternate name of the firm, since I cannot find any other business lines owned by it in a cursory search.
