You know, I remember Peter saying the efficiency of the regulator in the ARC AAA's was around 80% (or a little more?) Anybody know what the exact (or approximate) number is for the ARC LS and the newer ARC AAA's? Peter?
Efficiency of the regulator in the ARC LS

Peter,
Speaking of regulators. Is is possible to create a different model of the ARC LS, were the regulator is designed so that you can use 2 regular AA alkalines and it be as bright as the current production LS with 2 AA lithiums?
You wouldn't be able to use lithiums in this model because it might push the Luxeon too hard. But I would rather get the brightness of lithiums with less expensive alkalines. I'm sure battery life would be shorter but I would prefer the higher brightness.

Roger, the efficiency of the LS inverter varies around 70-80% depending on cell voltage, tempurature, etc.
Sean, like all our products, we can't leave them alone and are always making improvements. I have been working on a new design for the LS for some time now and probally will be for a lot longer. I think you'll approve of the improvements.

No, I haven't tested it since we modified the circuit a while back. Also, I really don't like to post those numbers anyways. You understand.

Uh - Peter - Efficiency numbers aren't exactly a trade secret once you ship a product - after all, anyone with a bench supply and a couple DMMs can measure Vin, Iin, Vout, and Iout and thus calculate (and even plot, using some HPIB equipment and HP-VEE software) your product's efficiency.
As shown on this group, reverse engineering is a common skill. Publish your "performance data" and people will be less likely to do it for you (and perhaps mis-spec your product!)
