5 LEDs & 2 AAs?

Hi, 1st time post.

I've seen an ad for a 5 led light driven by
2 AA cells. Of course it says very bright
light and 40 hrs. burn time.

Is this possible given that the voltage must
be stepped up to 3.6 volts and that one of
the most efficient setups (Infinity, 1 led,
1 AA) gives 40 hrs. of burn time. That is
.4 the battery chemistry for each led as the Infinity.

What can be expected from this setup?:
1. Bright light & 3 hrs. burn?
2. Dim light & 6 hrs. burn?
3. Or am I totally underestimating this setup?

Thanks, Rebus

Hi Rebus, welcome aboard!
I think the claims are way too high, given the fact there is only so much power in a battery...
Any chance of some more info? pics or a link maybe?

Welcome Rebus. By chance could this be the light you came across? If so, your doubts are well founded.

Galavanter,

Yep, thats the one. Wish I had read this
thread before I bid. Will post to your
thread when I test it out. Sure is a
nice looking piece thou.
