Hey experts
This is probably an easy one. I'm trying to build a simple flashlight from a standard 12V halogen spotlight for household use, and I need it to run on batteries. As far as I know, there are no commonly available (and cheap) 12V batteries available, so I imagined to make a battery pack from common battery types.
I don't want it to be too big, so 8 x 1,5V is not such a good idea - Also because I'd probably have to mount several in parallel in order to properly supply the spotlight.
Now the questions are:
- What voltages can these spotlights accept?
- What combination of batteries would you suggest to power the gadget?
- Are there other and better standard halogen spotlights, I should consider using?
To consider:
- The flashlight is not meant for sustained use - Just bursts of light 30-60 seconds at a time.
- Size does matter. 8x1,5 type D batteries is too large.
- Other suggested types of spotlight should have apprx. 30deg. beam and effect of 20-40W if its indeed possible to construct from batteries.
Thanks in advance for your ideas
