First off :welcome:
For your budget and your needs, it's going to have to be the
Romisen RC N3 II Q5 at shiningbeam.com (+10 for all previous references to this light), i personally own one and its a great little budget light.
It can be used as a 1xCR123 or RCR123 light and its very bright using RCR123s (which last in mine for about 45 minutes) but in this configuration its only got 1 mode.
It can also be used as a 2xAA light, i use mine with 2xEneloops and it is pretty darn bright too but of course not as bright as when its running on 1xRCR123. The low mode is useful to save cell life or if you dont want to ruin your night vision too badly.
And it uses a forward clicky, meaning you can do a 1/2 press without clicking fully to activate the light momentarily and also to change modes and fully click on when you reach the desired mode.
Since you already have eneloops, this should suit your needs. If you intend to use it in CR123 configuration, you can always get some RCR123s and a charger for not too much cash outlay and then can save on buying cells.
Lastly, seeing as how you have some eneloop AAAs lying around, swing on over to
4sevens and spend $15 (dont forget the 'CPF8' discount code) and get a Fenix E01 to use those AAAs in. That light will run for a really long time on a AAA. Its output is not bright and there's a slight purplish tint (only on white wall hunting, but in real life use its not that bad at all) but its enough light when its dark and you just need to see where you're going.
Of course you could just use the high mode to find the house number and low mode to walk up to the door (am assuming that you are doing deliveries) but hey, you're on CPF now, get with the program, get a BACKUP light
and the E01 is a great backup light.
