It is apparent from many letters we have received as a result of our recent advertisements in your publication that there exist two popular misconceptions about our quartz iodine conversion kit.
Firstly, there is no problem with excess heat and, secondly, there is no shortage of supply. We know of another much advertised Q.I.V. bulb which has not proved reliable and as a result is not generally available, but we are anxious to dispel any confusion between that product and our own.
