I just installed some 4" recessed cans in a remodeled bathroom and am choosing bulbs.
The Halo trim kits say that the max bulb wattage is a 50 Watt PAR20 or a 50 Watt R20.
So, I have a halogen bulb (an R20) that says "40 Watt = 75 Watt" which appears to be saying that this halogen bulb uses 40 Watt of electricity to produce light that is equivalent (in some sense) to a 75 Watt incandescent.
Question: is this R20 bulb ok for my 4" can? I think it is and in fact is slightly undersized since the trim kit allows a 50 Watt R20 and my R20 is only 40 Watt. Is that right? I probably should just ignore the incandescent comparison but I want to make sure.
