Not as homey and comfortable.

5. Halogen Lighting brighter than incandescent bulbs.
Light is more similar to that of sunlight.
Bulbs burn whiter than incandescent bulbs.

6. LED Light-Emitting Diodes Last 100,000 hours Consumes less energy
Gives off less heat
Initial cost is more

7. Light Temperature Light Temperature is rated in Kelvin
Orange (incandecent) K
White (halogen) K
Blue (fluorescent) 3000K for warm 4000K for cool

8. Color Rendering Index (CRI)
Indicates how well light from a source will bring out the true color.
CRI scale is from 1-100
100=color rendering of daylight
The closer the CRI is to 100 the more accurately the light will reproduce color

9. Measuring Light Wattage- The amount of electricity that is used
Lumen- the amount of light a bulb produces
Foot-candle- the amount of light a standard candle gives to an object 1 foot away
1 lumen per sq ft=1 foot-candle

10. Properties of Light

Absorbed light
Diffused light

11. Reflected light Light that bounces of a surface

Try to avoid glare

12. Absorbed Light Light that is drawn in by a surface
