I am bidding on a job that is different from my past experience and need some suggestions.
The first part of the project is going to require me to mount approx 3 fixtures in a tree 50 feet from the ground. These fixtures will be required to light the roof of the customers house which is approx 100 to 120 feet away from the fixture. I need to keep the beam pattern fairly tight on the roof with as little as possible splash over. I have a similar installation elsewhere on the property but the throw distance is around 80 to 100 feet. These fixtures will be straight security floods so I am not worried about beam pattern.
Given the height of the fixture and the distance I figured I would go with a metal halide fixture but I am not sure it will do the job. He understands he will have to hire a tree cutting company to change bulbs so I want to provide the longest possible bulb life. Can you recommend any specific fixtures?
