schematic for emergency lamp


I have T4 Fluorescent Lights (8W 24v '1Feet length') and 6v 4Ah battery.
I Would like to make an emergency lamp with these. Can anyone send me a curcuit diagram/schmatic.. Just manual switching on and off will also do.

Thank  you

With that battery 100% efficiency gives you 3h max on one tube. But you would need to build a ballast, or a DC-DC step-up to 24V.
It may be easier to get a 24V battery pack together, e.g.:
You'd get 7h for one tube out of something like that.

.  Try searching for something like:

(drop the +T4 for more generic hits)
