...but I was really impressed with the LL P7, and what it can do with 3AAA's...
Ooops, better make that 4 AAA's!

So true. When I'm scanning my top paddock I have a little grove of trees that I stand in, especially if it's raining, and shine the torch out. I can only do it effectively with the LL P7. When I use my quarks or Eagletacs the spill lights up the hangy downy parts of those trees so well that even if the spot is going a hundred yards outwards I can mostly only see the trees right in front of me., and the over-abundant spill actually interfered with the eye's ability to see farther into the throw by causing the pupils to contract. Basically, the lights spill was blinding me,...
Yes it sure does. :laughing:LL P7 still makes me smile every time.
Good quality freshly charged NiMH is ~1.45 volts, after a month it's ~1.35 volts.I DID read somewhere that the voltage of a freshly charged NiMH (straight off the charger) can exceed 1.2V by some margin. What you should do is let it cool for a few hours before using it. I wonder if this is the source of the manufacturers' concerns?
...why do they warn against rechargeable batteries (NiMH), and seeing as people on here have used them, is there really any problem?
Thanks for your comments folks. Now you mention it, I do now remember in Physics 101, a cell has an "open circuit" voltage, ie the voltage at zero or neglible current. If you increase the current draw, the voltage will fall. And I can see that the behaviour of different cell types might be different in these circumstances.
However, I still think, in an incandescent flashlight, rechargeables are dimmer than fresh alkalines, and that can only mean the circuit voltage is lower.
As for voltages, I'm surprised that NiMH are 1.35V. They only claim 1.2 or 1.25V maximum. You'd think they would claim 1.35V if that were true, because that would make them closer to standard cells at 1.5V.
That's why I said good quality NiMH.As for voltages, I'm surprised that NiMH are 1.35V. They only claim 1.2 or 1.25V maximum. You'd think they would claim 1.35V if that were true, because that would make them closer to standard cells at 1.5V.
...on the front it has a big red sticker "200 Lumens *". The asterix takes you to some small print on the side, and when you put your glasses on, you can see it says this can vary by +/-15%. Minus 15% from 200 and you get 170 Lumens, precisely the stated output of the previous version ?!!!
