some $urefire bulbs are Xenon Halogen and some are Xenon only....
fivemega,
with respect, my question is still hanging... excuse my attempt to focus down to it, and understand it may be based on conjecture... please bear with me, I had only one question, and I may have legitimately begged the question (i.e. formed the fallacy principio principii based on ampdude's generalization)
Only high powered Surefire lamps contain xenon-halogen.
P60, P90 and E series are xenon only.
Understood.
What is so different about Surefire bulbs in any configuration where they don't darken?
Here's what may be conjecture, and/or generalization, which I'm accepting as fact (is it?) to ask my question:
(and I should have added the first time,) "ignoring the high power Surefire lamps that use xenon-halogen,"
how do the xenon-only SF lamps stay clean with no halogen, thus no halogen cycle?
^---- forget the xenon-halogen Surefire lamps. Do the xenon-only non-high power Surefire lamps not darken, and if not, how do they accomplish that when other brands' xenon-only lamps darken (according to ampdude)?
You very nicely outline and explain why lamps darken in your last post. The suggestions there may very well be part of the answer to my question, which, again, is,
"Why don't SF xenon-only lamps darken? " -- ignoring the ones with halogen, as the halogen cycle is probably a good reason why the xenon-halogen SF lamps don't darken. What's up with the SF xenon-only lamps? Is ampdude's statement too general, inaccurate, wishful thinking, or is he just really lucky? Or do SF xenon-only lamps indeed resist darkening better than other branded lamps? IF so, how might they accomplish that? For the same reasons other lamps darken, i.e. coil tightness, bulb shape, etc., Surefire xenon-only lamps (also) do not ?
Sorry for the redundency, risking it to try to be clear to the max.
You can just say "the xenon-only Surefire lamps do exhibit darkening" if that is true... idky I'm making this so hard. SORRY. THANK YOU!
