need advice making homemade headlamp

I do a lot of fishing at nite, so I've made a few different headlights. Usually I use 2 AA batteries or 2 AAA's. They work fine, but I want a brighter light. Tonite I bought a 9 volt battery t ouse instead. Now, I don't really know much about watts and amps, but what happened is I got a great bright light, then I fried the bulb. The bulb was a Krypton 2.33 volt 6 amp. I've never really seen a 9 volt battery used for a flashlight, is there a reason for this? And. what other bulbs can I use that might be more powerful than the Krypton I use, is Halogen brighter? I would like to keep the weight low with the batteries, so I figure 2 AA's would be the most I want to carry. Thanks

You have lots of options with 2-3 rechargeable AA, LED and incandescent.

9V battery has only a 150 or so mAh capacity, as opposed to above 3000 mAh for an AA. It is also poor at high loads.

Sounds good. So what are some of the brightest bulbs I can use?

Yup, for a led headlight with a decent throw on 2AAs, have a look at the PrincetonTec Matrix 2. There's a couple of threads in this section on the PT M2, check it out...

I know you're trying to make your own, but I thought this thread might interest you.

Here's a headlamp I made. Direct driving two LEDs of different color, great light quality despite being ugly... just food for thought.
