Thanks for all the responses. In response to them:

I’d not mind if it was a small percentage lower output than claimed. But seemingly half the output is pretty low. I don’t think it was Astrolux lying about the output, especially if I’m the only one that feels that it’s weak. it’s still strong enough to be useful, just not what it should be. I do wonder if it’s possible if I somehow did any damage while getting rid of the next-memory mode problem. Either that, or maybe I did just get some bad luck with quality control or premature failure.

I haven’t tried to return the A01, mainly because it’s still putting out a usable amount of light on high, just disappointing. It was also so inexpensive that the effort spent wouldn’t be worth it (unless it had been completely DOA). I did consider buying a second just to compare, but decided against it, as I still have three other AAA lights to use (why I feel the need to have so many is another issue…)

I thought to do a time test on it the A01 though; perhaps if it lasts longer than expected on high to go along with its seemingly diminished output, I’d be able to consider it a feature instead of a flaw.

I did contact the store on the site from where I purchased the M01, as I only received that a little over a week ago. It hasn’t been enough time for them to respond to me.

I hadn’t considered it a problem with the battery in the M01. I did charge it back to full capacity (via the flashlight itself) and the problem persists, but as stated, it may be a bum battery. I’m not sure it’s worth going down the road of buying another battery or another 10180 flashlight either.

I guess I will just have to consider it unfortunate luck and move on. As I said, the A01 is still usable, good for around the house. The M01’s low mode is still a good amount of light too for a nightstand. I’ll probably let my six year old keep it in her room near her bed until it totally dies.

Any other comments or suggestions are still welcome. I don’t want to tarnish a company’s name due to bad luck, but I do like to hear if others had similar problems.
