I got one a few weeks ago.
1. It is hefty and of good construction.
2. Does not have a SF style lamp assembly regardless of the SF illustrations on the hang card. Nor does it have a LOTC.
3. It is a basic design similar to the original SF 6P in many aspects.
4. The lamp assembly is a threaded setup similar to the ozark trails 2AA at Wal Mart (Garrity I think) where a resistor can be inserted to drive a 1 watt LS. LS could go on the other side as it is already an aluminum heat sink but the bulb hole would need plugging.
5. You might loose too much reflector to get decent penetration of a LS LD but not a HD I think.
I might get the urge someday and fix mine up.
