Now all we need is a cheap host to handle the massive drivers and reflectors. Anyone have any ideas? Also, the SST-90 driver might be a good choice for slightly overdriving an SST-50 for a mag thrower or similar.
I think the 7cm one is too big for a Maglite head - it is only 52-54mm inside diameter. The WF-500 is about the same, maybe a little larger. It certainly isn't 70mm. I don't own anything that would take a 70mm reflector.
