Our condo has mounts for these weird CFLs in the common areas so they were ordered to replace some of them that were out of service. If our club has sufficient funds, plans are in place to replace the fixtures with ones that use LED bulbs that can be screwed in, replacing the 4-prong snap-in style bulbs and requiring ballasts in each fixture are. LEDs are more efficient and last longer.
