Help! I am building a device that needs a power hungry halogen bulb
(5V, 0.8 amperes). With a standard 9V NiCad battery and
5V rectifier I only get 1.5 minutes of useable light. I could use
4 1.5 (actually 1.2 V) NiCads, but these would take up more space
(space is important). There was talk of  "VARTA"  batteries packing
more energy into the same 9V size.  Where are these available (esp.
in Canada?)  Any other suggestions for power sources. I need to use
Halogen bulbs because of its colour temperature: its much whiter
than incandescent bulbs. Any suggestions on other sources for
Halogens?

Your suggestions would be most appretiated.
