Halogen PAR20 120 Volt 35 Watt Narrow 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 - 50W. Other beam spreads available - narrow flood and wide flood. GEL
