GE R63 reflectors come with an edison screw base and are designed to focus the beam of light in one direction, which in turn increases the light intensity.
Upgrade to a greener solution
There are two "green upgrades" for the 60W R63 reflector, the most efficient solution is the 11W Megaman R63 reflector (80% energy savings - 15,000 hour lamp life) but if you do not like fluorescent lighting then we also stock the popular halogen, energy-saving Osram 42W R63 Reflectors (30% energy savings - 2,000 hour lamp life), these lamps are a great entry point to energy saving lamps.
