They have extremely weak and thin forks that don't fit the socket. We're not talking low-level lighting here. Our outdoor units - FX Luminaire! The bulbs are loose, do not sit well in the cartridges and accordingly do not burn. Okay, some connectors, even for FX Luminaire, may be different. Other than that I've never had any problems. The ends of the plug are useless, making the lamps useless! "RETURN" - KEYWORD!
