# Understanding watts available in miniature batteries?

I am doing a project with some small miniature incandescent light bulbs (like a CM7333).

Sorry for not providing more links, the system will only allow 2.

The power source is a E11A battery.

The issue I am having is the bulb is not bright enough. We need to basically double or triple its current light out put or lumens. Theses bulbs are rated in MSCP. something Candle Power I presume.

These little bulbs are available with different amp, volt, and MSCP ratings, as precribed in this [chart][3].

Ok, so it would seem a simple matter of getting a bulb with an increased amp rating or filament design (I want to use the same battery in my design, which is 6v) so the total watts is higher and hence the bulb will burn brighter. From the [chart][4]

I could say grab a CM3150 which indicates a MSCP rating 3 times higher than the current bulb I am working with, for the same Volts and amps. I assume it brighter because the filament is a lighter duty design, which burns brighter. At least that's my way of wrapping my mind around it.

This were I run into my question or were I need some education. These little batteries seem to have some kind of current limiting capability or attribute. I have reviewed the technical data but its not clear to me how many amps the battery can supply.

I don't know how to properly determine how many amps my little battery will provide. I know it says "38 mAh to 3.0 volts", but I dont know how to properly apply that. The data sheet also states the drain as ".5 mA continuous", if I ma reading it correctly. Does that mean the battery can provide .5 mAs. or .0005 of an amp? Is it saying HALF a miliamp? or half a amp? half an amp sounds like a lot and half a milliamp sounds tiny.

So, in closing I hope I asked my question in a way that can be understood. Basically, I need to understand the maximum out put of that battery in even divisions of the amp. Like my bench top power supply. .01 .357, etc. Do these little guys have a current limit over time. I don't think they can discharge all their energy in a second... I think its the current limiting that is preventing my bulb from burning brighter... I dont know
