Also, do you want illuminate from inside the 2x10 foot generic 'object', or spotlight it from some similarly generic distance?
Is the 'object' light/reflective or dark?
Does the 'object' need to be just visible, or do you need enough light to view details, like on a sign?
The more specific details you provide, the more likely you will get a useful response, instead of more questions. Lots of people pass over thread with such mystery request, instead of even guessing at what you are trying to do. Why spend time working out a solution, not knowing if it will be immediately discarded as not what you had in mind. We have our own projects, but don't mind taking a break to help out others in need.
