[edit in] where's my manners!, looks like you are new to the forum, WELCOME TO CPF!!!
if you have a harbor freight in the area- go down and pick up a 10 million or 15 million "candlepower" spothlight... they are big and heavy and don't run very long... but you will definetally **** off the neighbors... not that I am recomending you do that...
other places that carry them: auto parts stores, costco, hardware stores, some places online...
price is usually around $25-75...
here's some ideas...

stuff like that...
don't concern yourself too much with candlepower ratings...when dealing with lights of this caliber, the manufactures are not using candlepower ratings properly- they are exagerating and using the big huge numbers as a selling point. (in the same way that manufactures of crapp stereo equipment put "1000 watts" on their little 10 inch woofer)
The "1 million" candle power lights, are generally ~55 watts
the "3 million" are generally around ~75 watts
the "10 million" are ~100 watts
and the "15 million" are ~130W
they are all prettty bright, and cheap and easy to obtain.
