I need to *temporarily* install an outside light on one side of my
property overlooking a lawn - as it's only to be used for a month or
two I don't want to go to the hassle of running a length of wire, etc.

So, bearing all that in mind, I have two theories:

a) Get a battery powered light that I can put outside (doesn't even
need to be waterproof as perhaps it could be brought in if necessary).
A halogen torch wouldn't be powerful enough (it wouldn't give a good
enough spread of light - the area to be illuminated is about 30 feet
across by 15 feet deep). Batteries would need to be rechargeable.

b) Get some kind of mains powered light that could be mounted *inside*
a window and hence plugged into the mains.

Any thoughts anyone and recommendations on anything suitable please?


Thanks
