Ok, I've followed this thread, and it seems to me that you need a really rugged light, with long lasting, easy to change, rechargeable batteries.
The Dereelight I mentioned in my first post, on the low setting (which should be plenty bright for 99% of your needs) will give you about 20 hours of light from each charge. So, let's see, half an hour a day, 6 days a week is 3 hours...... so you should be able to go for 6 weeks between battery charges (let's just say once a month to be safe). Pretty neat.
And, if you ever need it, just twist the front of the light a bit for the high mode, a blinding almost 180 or more lumens of light. Very neat, even if only to impress your friends.
The rear clicky is a momentary, so press a little bit for on, then just unpress for off..... or fully click for on.
From all reviews so far, it appears to be
very rugged. Here is the link again to the purchasing page:

Here is a link to a review with lots of pictures showing how well it fits in the hand, and it has an excellent clip for fitting in a pocket:

Here are the rechargeable batteries (it needs 1, so get 2):

Here is the charger:

Also get 4 primary batteries (just in case the power goes out, it needs 2 of these, so get 4):

All of those links are to a place called "Lighthound". You can get everything you need there, so just one shipping charge. I would recommend that you call them and tell them that you are a new CPF member, tell them what you are thinking about getting, and see what they can do for you.
Let's see:
Dereelight 2 stage light:.............$70
2x18650 rechargeable batteries:...25
Charger:...................................17
4xprimary batteries:................
....9
total:................................... $121
Ok, you can knock off $9 by forgetting the primary batteries. That brings it down to $112, very close to your top limit, and you could knock of another $12 and just get one rechargeable battery... that's $100 even...... for a top quality, versatile, rugged, long running light, including a rechargeable battery and charger. Not bad.
Or...... you could go this way, with a 2xAA light, available at Walmart for about $25:

And 4xAA rechargeable batteries and a charger, about $27 including shipping (available at Circuit city for about $30):

So, about $55 for a good alternative. It's nice to have choices.
