Bulbrite brand MR16 halogen flood. 50 Watts for more power and light. 120 volts for line voltage systems. Higher voltage means no nead for a transformer, and less power lost as heat.
Halogen lights provide brighter, whiter light than incandescents, while maintaining outstanding color rendering
Flood means 38º beam spread and a wider beam of light. Lamp can be closer and still light the area effectively
Dichroic reflector reflects visible light out the front while letting heat escape out the back, resulting in a cool beam of light
Glass lens - enclosed fixture not necessary
