The performance of any light fixture depends on the light source (bulb) used. Different sources produce different effects. Light is measured in terms of wattage (the amount of electricity consumed by the bulb) and lumens (the amount of light that a bulb produces) and foot-candles (the amount of light reaching a subject). Here is a brief description of the types of bulbs available today. Incandescent bulbs: Incandescent bulbs are inexpensive
and readily available in a variety of wattages and shapes. They produce
a yellowish-white light that is emitted in all directions. They are available
in either clear or frosted. General (A), Globe (G) Decorative (D), Reflective coating inside the bulb directs light forward, giving you better beam control than general service bulbs. Flood types (FL) spread light. Spot types (SP) concentrate the light. Reflector (R) bulbs put approximately double the amount of light (foot-candles) on the subject as General Service (A) of same wattage. Parabolic Reflector (PAR) bulbs control light more precisely. They produce about four times the light of General Service (A) and are used in recessed and track lighting. Weatherproof casing makes them suitable for outdoor spot and flood fixtures. TUNGSTEN-HALOGEN T-3 Double Ended bulbs are available in a variety of base types and are used in wall sconces, Torchieres, and outdoor floodlights. The direction of the light is controlled by the fixture. T-4 Single-Ended bulbs come in both mini-can and bayonet base types and are used in wall sconces, bath bracket, Torchieres, and pendants. The direction of the light is controlled by the fixture. FLUORESCENT HIGH-INTENSITY DISCHARGE High-intensity discharge (hid) bulbs have a longer life and provide more light (lumens) per watt than any other light source. Available in mercury vapor, metal halide, high- and low- pressure sodium types. Used residentially for outdoor security and landscape lighting. top of page |
