Task lighting provides enough illumination that tasks can be completed accurately but not so much light that entire areas are illuminated. Accent lighting illuminates walls so they blend more closely with naturally bright areas like ceilings and windows. Incandescent is the least expensive to buy and the most expensive to operate. It has the shortest life span of the common lighting types and is relatively inefficient compared with other lighting types. The most common types of incandescent lights are standard incandescent and tungsten halogen.
Excessive wattage creates unnecessarily high illumination.
Select the right incandescent lamp for the job. New incandescent fixtures are designed to force all their light out into the room. The ER lamps outperform R lamps because of how the light is reflected out of the lamp. Although long-life bulbs last longer than their regular counterparts, they are normally less energy efficient. They are considerably more expensive than standard incandescent.
