Well, I only use Ni Mhs for AAs, so I'll go with a bad boy (if I save enough) or the Terralux. Haven't heard about the InReTech though

an excellent idea!

i like both the Madmax and the Badboy. both will eat any bat you care to stick in it.

if i were to use mostly alkies, and did not mind the light gradually dimming, i would choose the madmax lite. it will use the bats down to nothing. or, you can feed it bats that are too drained to run other stuff--like digicam bats.

what is interesting is that i tried my BB400's with good alkies. they fell out of regulation at about 2 hrs.
with 2100 NIMH they fell out of regulation at around 2:40!
(this was with the stock low-dome. i have since changed them to lux3 high domes)

oh, and the madmax lite should still get good runtime, because i think the LED is only getting about 400ma.
the madmax plus runs at around 800ma! i gave one to a friend and he LOVES it! i tend to like longer runtimes, however.

i think that the rechargeables (as well as lithiums) will give a madmax a flatter discharge curve--but i havent tried it. but, since the madmax will grind the bats down to 0.8v, you have to be careful so you dont damage the rechargeables.

if you can save your pennies, i think the badboy/madmax would be worth it. add a mineral glass and a kroll clickie to round out the package.

if you really cannot afford the BB/MM, then the terralux or lambda's drop-in will still amaze you!
even my wife is floored when she picks up one of my lights, and expects a feeble ringy-yellow beam...and gets a wonderful bright white wall o' light.

oops...the inretech. it is a "direct drive" light, which means that the LED runs right off direct battery voltage. the nice thing is that there are no electronics, and runtime is crazy-long.
the bad thing is that they tend to be dimmer than a LED fed by a circuit. it will probably be even dimmer with NIMH, due to their lower voltage.
remember, most Luxeons like 3.5v and about 350ma, and the inretech will only provide 3v with alkies, and probably 2.4 to 2.8v with NIMH.
however, the inretech brightens up nicely if you use lithiums (which are often ~1.75v/cell, or 3.5v total).

holy cow, i have learned a LOT here at CPF!
there are many very bright people here!

anyway, take care,

Bob
 
Ok, I'll save my pennies. This is not a "I need it now" thing.
So the BB will suddenly die, the MM will gradually dim, like the unregulated InReTech? What about the Terralux, how is the discharge on that?
BB400 is in my sights.
 
GarageBoy,

Check kj's runtime plots in the Review Forum. You can see what the runtime look like for the BB & MM.

yes, check out the runtime plots. they are under "reviews". i think the led museum and quickbeam have some runtime plots as well. GREAT stuff!

the BB will rather suddenly become dimmer, but it will still give useful light for some time.

some see this as negative. they prefer the slow dimming of the madmax, so they know where they are charge-wise.
the badboy can be hard to tell how much juice you have left--but you will always have the same level of light.

the nice thing about the badboy, is that when it falls out of regulation, this tells you it is time to recharge the bats. it kind of protects them from over-discharge.

i believe that Wayne designed the badboy with rechargeables in mind--it really is a very sweet and under-rated design.

I bought the Terralux. ~$25 + shipping. I am very pleased. A very simple conversion.
 
i just re-read the reviews on the terralux, and it appears to be a pretty nice unit. nice price, too.

i was hesitant to recommend it because i havent tried one. also, some have stated that it becomes very hot, which could shorten the life of the LED.

still, it has been liked by many.

choices, choices...
