than me could explain it better, but essentially it’s their construction. Screw-in pills, EZ900 XRE’s, really nice aluminum reflectors, nice machining, anodizing, solid-brass flat machined surfaced tail-cap negative spring contacts, glass lenses, nice tight hot spot, throws plenty well, all in all for when they were at $7.69, well kinda an unbeatable thing. I hope they go back on sale again.
The only thing I don’t like about them is next memory 5-mode. But I just take care of that by solder-bridging the C1 Capacitor to make it just one-mode. I think Pulsar13 solders on a 1 megaohm resister over said C1 and he shortens the going back to high after shut off to the tune of just 3 secs.
Here’s one good thread on that general subject……
