OK, here's more information about my needs:
Price: $50 to $100 I hope.
Throw: for around home (in the country) 200-300 feet would be nice; for keeping from getting hit by a power boat while canoeing at night, I'd want to be seen from at least 1000 feet, and figuring 30 mph is 44 feet per second, maybe that is inadequate. We've used Brinkman 6 volt lanterns for this purpose, and haven't had any close calls. I suppose that a strobe would be particularly helpful if a power boat operator looking our way was also looking at lights behind us on shore.
Spill: for around home, I'd rather not have a hot spot at all, but from the reading I've done on this site, there may not be anything like that available. Maybe a defuser has to be used. It would be nice to have a beam say 70 to 80 degrees wide.
Run time: though more is better, this won't be the deciding factor.
Preferred battery: I only have used alkaline types. From the reading on this site, I understand that there are good reasons why higher performance lights thrive on better batteries, and if need be, I will switch. In such case rechargeable LiI sounds good to me, but I don't know what I'm talking about.
Size of batteries: I really like carrying a 2AA MagLight in my pants pocket with the lanyard hanging down outside. A quick grab for the lanyard and the light is in my hand. However a larger light would be fine. I think that going smaller than 2AA batteries must mean compromises on battery life and/or light output so if I'm right, I would stay away from single battery and AAA units.
Preferred shape: I'm used to flashlight shapes and lantern shapes. The only thing I am not used to is L-shaped flashlights.
One thing I really like about the Mag lights (mine are actually Brinkman clones of MagLights) is that if the batteries are not dead, the light will work. No need to slap the light around to make the electrical contacts work, and most ordinary 2D flashlights do suffer this problem, even if I stretch the spring out a bit.
I won't be surprised if others on the forum tell me I need more than one light. Thanks in advance for your replies.
