ALP Convert-a-Strip kit includes an eight foot ballast cover, all required medium bipin lampholders, snap-in sockets , TEK screws and other hardware needed to convert an eight foot light fixture that uses one eight foot fluorescent light bulb into a fixture that uses easier-to-handle four foot lamps. The included ballast cover is pre-punched for ballast mounting bolts and sockets, and is pre-painted white steel with 91 percent reflectance. Special benefits of this kit include the fact that the old ballast does not need to be removed, the unit can be completeley wired on the ground before installation, and no special tools are required. CAS 84LH can be used with two RA 2004 relectors to increase performance.
