The purpose of this post is to see what others are doing, or to talk through a proper design:
Metal Halide:
Using metal halide lamps is standard for exterior lighting mainly due to the durability of the fixture. But, I don?t like the option available for exit discharge emergency lighting! It?s a battery inside with built in halogen lamp next to the HID lamp. The light output has got to be bad. I?ve been told this is the wrong application! The reason for the halogen addition is for some illumination while the HID warms up.
Compact Fluorescent:
So, we switch to a compact fluorescent, but you have the issue of cold weather ballasts. Also, test switches for the emergency ballast are dry location rated, thus we need to put them inside the building which is ugly.
Wall pak:
If it is possible to put a wall sconce (or not a glass wall), we can use Lithonia?s Affinity (AFN) that works like an old style emergency light (always off except for emergencies). I don?t like this because I?d like to stay with a standard design and I don?t like lights that are never on or would prefer to use the general illumination source and back it up.
Your opinion or office standard and why is greatly appreciated.
Thanks,
Joe
