Has anyone tried lithium batteries in lights?
I saw some Lithium AA's in my local supermarket, advertised specifically for digi-cams. They're about twice the price of premium alkaline AA's but if they last a lot longer they might be worth while. Are LED lights likely to be a high enough drain for them to make much of a difference?
I use Nimh for my main front lights, but like the Alkaline 'fade' for the rear, rather than the Nimh 'stop' for the rear, to get replacements.
