Lamp shades are corrective devices given to lamps to allow their light to come at more eye friendly levels. Different styles have arisen over the years, from special shades which change to a proportional darkness level of the light given off, to some which are simply for style, such as the ever popular Aviator shades.
In gardening terms, there are various types of shade:
- Full sun - more than five hours of direct sun per day.
- Part shade - two to five hours of direct sun, or all-day dappled sun (sunlight shining through open trees).
- Full shade - less than two hours of direct sun per day.
