I've finished a prototype of a searchlight using a 3 watt high power RGB LED.  

This is the light only, no proper tower yet.

   

The above are red, yellow and green.  

The colors look much better to the naked eye,
something about photographing them shifts the color spectrum. 

I can clearly differentiate the 3 from 200', so it does what I need.  

And I think they will be much brighter when refined,
I didn't have the proper current limiting resistor on hand. 

This is using about 120mA of forward current,
the final version will be more like 350mA.
