Alkaline bateries vs Mi-Mh

[spanish]

I have some spot lights (luxeon 5w 3 x AAA, Minimaglite TLE-5 2AA and a 3D cell scanner (like Maglite) and alwais use Mi-Mh cells.

How big is the diference (intensity and time to use) with the two types pf batteries?

I doubt you would notice much it may get dimmer when it dimms but the rechargability will solve yoru woose.

I think NiMh will give you flatter regulation and an increase in runtime due to there being less internal resistance. With alkalines, some enegy is lost due to its internal resistance in high drain applications. You would probably not notice the difference in brightness due to the NiMh being 1.2 volts as oposed to alkaline's 1.5 Volts. NiMh are also cheaper to use in the long run and better for the environment. I have only minimal knowledge in this area so any other CPF'er out there with more knowledge and experience please chime in and correct me if I am mistaken.

I have been using alkaline's in my VIP, and Arc LS, both current regulated. One of my VIP's is set for three levels of light, 50mA's to led, 330 or so mA's, and 660, or so mA's to led. Runtime at the lowest power requirement, 50mA's to led is excellent, and also very good at 330mA's, though not spectacular, and is much better at that current using nimh's.

My Arc LS is set up for 250mA's to led, and runs 3 hours in full regulation with alkalines, and an hour longer using one CR123. NiMh's would improve runtime.

High drain applications do much better using nimh's when the light is regulated. Direct drive applications, or direct drive with a resister lights fare better, intensity, wise using alkaline's.
