Hello! Please forgive me if I seem ignorant, but I have been wondering why it is that CHE's cannot be used as the main source of heat in an enclosure during the day. Every basking bulb I have purchased fails within a year (and they are in the correct dome) whereas the ceramic heat emitters I have for a few of my snakes last many years and are much less fragile! Is it something to do with the strength of the beam? I'm sure that someone has answered this at one point, but I can't seem to find it. Thank you!
