Daylight bulbs

Daylight bulbs are also suitable for use in SAD (Seasonal Affective Disorder) such as light boxes and alarm clocks etc.

Comparing light bulbs

When you're comparing light bulbs to decide which one to buy, remember that light output is measured in lumens. Some bulbs produce more lumens for the same amount of electricity (measured in watts), which means that not all bulbs of the same wattage are the same brightness.
