Thanks, that's a shame, I thought it might have full time constant like an armytek. Still a cracking light though.
I am getting the sense that you don't know what stepped regulation is, though it's presumptuous of me to think so. In any case, there will be readers who don't know, so here's the deal.
True fixed regulation, like presumably the Armytek, holds the setting absolutely flat, until the battery can no longer support that level any more; the end behavior after that is unspecified. Without further specification, the light might go out instantly at that point. Or it might dim out smoothly. Or it could (gasp) step down in an orderly fashion. Or conceivably it could do other things, like start flickering. I don't know which one of those the Armytek does.
True stepped flat regulation, like the SC600 Mk II and the HDS EDC, holds the setting absolutely flat until, in the judgement of the designer, the real time measured state of the battery no longer can support that level with safety to the battery. Then it steps down to a reduced level, and there can be a number of such steps, ending with again unspecified behavior at the absolute end of light production.
That's right, those who read carefully. They are pretty much the SAME THING. The stepped flat is nothing but a subset of the fixed. Neither one can hold that flat setting when the battery can't maintain it any more. Either one has to do SOMETHING at that point. The only wiggle room is how close either one lets the battery get to the irreduceable limit before either stepping down or going out, and in my experience they never tell you that. You have to wait for a graph of lumens versus run time from a test.
Anyway, thank you Tulip bush, you got me to check the Armytek site. Those are some sweet lights, and I don't think I'm going to be able to resist a Predator Pro 2.5 or perhaps a Viking Pro 2.5, but probably the former because it is a quite different beam from my SC600 Mk I. It will probably get here before my old Mk II order!
Note to, ahem, "all" other manufacturers. How can Armytek offer free DHL worldwide on orders over $95.00 while they use the slow boat from China?
. So the predator and viking are like the sc600 II with regards to stepped, but the pro predator and viking are constant from start to finish. I think I've got it. I'm going to read it again and hopefully the penny will drop,,,,, I'm not the brightest of people:duh2:.
