Re: Silverstar 9006XS/ST lowbeams vs standard Halogens
out of interest, how do you get a colour temperature of a match flame
at 1900K when wood burns at less than 500K ?

Good question. I dunno. I'm a lighting guy, not a combustion guy and I
do my best to not let people light with firewood in favor of a nice,
controlled tungsten light, a flicker box and some colored gels. My SWAG
would be that it has to do with thermal mass, the unburned firewood
holding the temperature down, but that's just a SWAG.

Re: Silverstar 9006XS/ST lowbeams vs standard Halogens
The match, like wood, gives off combustible gases when heated above
some mumble mumble [451 F] degrees. However that doesn't mean that
the match flame is 1900 Kelvin, it just means it is roughly the
same color as a blackbody radiator heated to 1900 K.
