Halogen PAR16 130 Volt 40 Watt Spot Light Bulb. PAR lamps are great for directional accent lighting without requiring the use of a specialized ballast or fixture. The mirrored coating inside the PAR directs light forward into a controlled beam. This gives the decorator more directional control than with most standard light bulbs. For use indoors or outdoors. Other wattages available - 60W and 75W. Other beam spreads available - flood. GEL
