[Stoves] Gas lamp efficiency

[Ken Boak]

Andrew and Stovers,

Here is one Chinese company offering lower cost TEMs.   Hi-Z being based in
the USA will certainly  not be the cheapest.

If you scroll down to the bottom of the page you will see an application
where 4 modules have been bonded to the bottom of a saucepan, and the
current produced is lighting a compact fluorescent lamp.

Modern electronic design could produce a compact, low cost and efficient
inverter to power these CFL bulbs from a varying dc supply, or power some
white LEDs.  The inverter need only cost about 50 US cents.

Whilst white LEDs are fairly efficient, they are really only suitable for
spot lighting - such as a substitute for a desk reading lamp, and CFL is
better for lighting an area - a 20W CFL will easily light a room of 16 m2 or
more.
