Hmmm...  too much???  Explain...  Do you mean that 160w is all heat and
maybe half of it is output???  That seems more sensible then Eric's
explanation because I tried just one bulb but it did'nt help.  Indeed
the temperature went up, but a large fan cooled the bulbs down.  End
result?  Temperature of about 80.
