How Do I tell when my AAA is in Moon mode ?

Looks slightly dimmer now, but is it in moon mode or un reg?

Try putting in a used up battery. If it lights up very dimly, that's moon mode /ubbthreads/images/graemlins/smile.gif
Otherwise, I have no idea how to describe it /ubbthreads/images/graemlins/wink.gif

Moon mode is so dim, that in normal light you can barely tell that the led is lit. "Slightly dimmer" is just the battery voltage getting lower. There is still lots of life left. Moon mode is almost useless. When you hit moon mode, shut off the light and wait a minute for the cell to recover, and you will have a fair amount of normal mode left. The Arc aaa is capable of operating normally on a remarkably weak battery.

So moon mode is unregulated?

Moon Mode is %50 of Sun Mode - Barely On Mode is not the same thing as Moon Mode. Moon Mode ends and barely on mode means there is not much left in the batt. Its not a mode really but a fact of life.

Moon Mode is Regulated

When I can look into the bulb without pain, it's time to change the battery.

an arc aaa with a fresh battery causes me no pain

Hi Marked

Hold it up to a wolf and see if it howles. If it does, it's in moon mode.

Batt is @ 1.0 volts

Despite Arc's deservedly great reputation, I always considered it a bit of false advertising to state a moon mode for the AAA. The light is only semi-regulated. It has a slower but steady drain curve, just much less pronounced then an unregulated light. To decide when it is in moon mode is arbitrarily up to the user. Now with an Arc LS (don't own a Arc4), you can definitely tell when it is in moon mode as it falls out of regulation quite quickly.

I can't wait for the Lithium AAA's. Because of the low current consumption, I doubt it will extend the battery life significantly but I'm hoping it will flatten out the semi-regulated drain curve.

It seems to me that the AAA really does have a moon mode, that it enters rather suddenly. That moon mode is extremely dim. It's better than nothing in total blackness when you're dark adapted, but otherwise is basically useless. This is in contrast with the Arc LS, which drops to about Arc AAA level in moon mode and is quite usable that way.

How long does it stay in moon?

Ok, yesterday my Arc AAA was running in a dim, but usable mode. Then when I turned it off and back on, it didnt work. Restd it for a few mins, tried again, it lit. Same thing happened today, only it wouldn't relight. New batt= prob solved. So the batt is TOTALLY wiped? Also, what voltages will the AAA go into moon mode and then "dead" mode?
