Default Re: Crompton 60W bulb

Because orange or amber fireglow lamps were used in electric fires, there arose a widespread and erroneous belief that such lamps were "more warming" than other colours .
Use in electric bed warmers as described a few posts back was very common, when in fact a standard clear or pearl lamp would have worked just as well and been cheaper.

Red or orange lamps of low power were widely used as nightlights in school dormitories and similar places, minimum sleep disturbance but enough light to safely walk around if need be.
