I think the idea someone posted of using a lower wattage bulb makes a
lot more sense!

Me too. Another alternative is a higher-voltage bulb.

Possible problems with a higher voltage bulb: 12 volt 20 watt strikes
me as likely being halogen. One problem is finding a version designed for
a moderately higher voltage and with the same style base.

Another problem is that when a halogen bulb is underpowered, the halogen
cycle does not always work. Theoretically, evaporation of the filament is
supposed to slow more than the halogen cycle slows if the bulb is
underpowered, but it does not always work that way. One problem that
sometimes occurs from underpowering a halogen bulb is that the halogen
cycle slows more than a "reverse halogen cycle" performed by contaminants,
and the bulb could get blackened with filament material. This is more
likely with el-cheapo halogens from manufacturers other than GE, Philips,
Osram/Sylvania and Ushio.

One fix is to use a non-halogen 28V bulb, but then you will need a
different socket, which may refuse to fit and may not be nearly as easy to
get as a 10 watt 12V halogen bulb.
