Does anyone else use this light? I upgraded to the xpr113 bulb from radio shack and I think this light is amazing. wouldnt this make it as bright as a 4 cell mag? I was looking over the other lights but most the bulbs are to costly and need to be special ordered online. if my bulb burns out in this I can run down to radio shack and grab a new one. Lately I've just been into led lights (especially the attitude) but when I'm outside my tec40 gives me much better range. Its useful for checking over the yard at night if you hear something outside. I was also thinking of a surge but that just makes more bulk and needs a special bulb. with nimh cells and the easy to find bulb this is my favorite incandesent light. how well will this light compare to future luxeon star flashlights? any other opinions on the tec 40?
