Battery powered led transformer

Hi All,
i have to fit a small 40cm x 30cm sign in a remote location with lighting. I remember seeing at a sign show once a 9v battery powered LED transformer. Has anyone seen anything similiar? or can guide me in the right direction? i was just going to run some leds off a 9v battery? or a solar panel?


cheers

Dan

As MOST LEDs used for signage lighting work off a 12v supply why not use a small NiCad pack.

No need for any fancy widgets then.
