Do I need A Led Showerhead Or What?

[Spin]

I have a 12 volt dc, 8 amp rechargeable lead acid battery. I want to use this with white led's for a possible power failure of three days. I only need enough light so i won't walk into anything. I can turn it off during the day. Is there an led attachment i can purchase to accomplish the above?
