Energy Saving Daylight Bulbs
Different types of environment generally require different types of light source and colour. Many employers find it useful to use daylight tubes to illuminate their workspaces, owing to their generous light output, wider spectrum and superior CRI (more on these last two later).
Most people in north western Europe spend much of their working lives indoors, either in offices, warehouses or other enclosed spaces. This can ultimately deprive them of the natural daylight they would normally receive from direct sunlight. While this can make for a pretty miserable working environment, in extreme circumstances it can also cause certain psychological disorders such as SAD...
Seasonal Affective Disorder (SAD) affects a large number of people in the UK, particularly during the winter months. The prolonged nights and shortened days of winter limit the amount of sunlight many people receive during the darkest winter months. A notable treatment for these symptoms is the use of full spectrum daylight tubes that can adequately mimimc the quality and spectrum of light provided by natural daylight.

The Colour Rendering Index is an industry standard reference to a bulb's ability to render the colour of an object it is illuminating correctly. Codes range from 0 to 100, with the higher numbers denoting more vivid and lively results. A lower CRI rating produces more ghostly (faded, dead) effects. If you want certain items to look good under lights - either for photographic or display purposes - then a higher CRI is required.
Bulbs with a high CRI rating generally cost more to buy and more to operate as they yield fewer lumens per watt consumed. Lower CRI bulbs put out lower quality light but are very cheap to operate as they have a higher lumen to watt ratio.
