Rated 5 out of 5 by RayL obstruction lights
I use these on the airport beacon's obstruction lights. Color is perfect and bright. TCP fit all the FAA qualifications in regards to temp, lumens, color, and operating temperature. Their long life has paid off ny not having to climb the tower every other month to change bulbs, which in turn, makes these bulbs a safer workplace. They also operate in enclosed fixtures, many CFLs do not. Recommended.
