would love to know how they compare in throw and otherwise
You must look at the ends of the extension. On the end with external threads the very end should have a round circle of silver where it makes contact. The other end with internal threads should have the internally threaded part which leads down to a large silver circle. The tailcap must contact the silver circle on the end, and the original battery tube should contact the internal silver circle. Finally the pill has to make good contact. That means the lens part must be very tight. I had the same problem with the host I bought with both of the drop-ins I bought. I already had the smooth reflector for the xre pill and I bought a mce pill just for fun. The mce is not that much more light than the xpg but is very floody. The xre however is a very good thrower even though it has less total output. It is most assuredly one of these problems. Contact either at the extension or the pill. The only reason I am so persistent is well its my job to fix things, and it is a very good light made marginally better by the third aa. I think I'll get an 18650 host for the mce. If you do by other pills remember to get the low voltage ones. The price for the host was only $28. That's a steal. If you pinch an oring on the internal thread end, it is never going to light. You might try taking those orings off as a test.
