Compact fluorescent lamps

Compact fluorescent lamps (CFLs) are a type of light bulb utilising fluorescent technology in whcih the fuorescent tube is wrapped in ways that make its form factor smaller and similar to traditional light bulb shapes. The fluorescent ballast is normally compacted into the stalk of the bulb so that it can be used in standard light bulb sockets. CFLs are very popular as a product because they emit more light per watt than standard incandescent bulbs do, although they are being rapidly replaced by newer LED bulbs which are even more efficient. CFLs are also a source of HEV light (blue light).

By modern lighting, this means LED bulbs and compact fluorescent lamps (CFLs), computer screens and mobile phone screens amongst others. The effects are wide-ranging and interesting personally.
