The incandescent lamp has been used in households for more than 120 years and has long been proven to be reliable, easy to use and apart of a cozy and inviting environment. Over the last decade, a major initiative to develop more efficient light sources has replaced much of the worlds general service incandescent lamps. Nevertheless, many decorative or specialized applications still require the specific attributes of incandescent lighting. Incandescent lamps provide the best possible colour rendering which, serves as the colour standard by which all other lamps are measured. Not only do they offer aesthetics and flexibility, they also do not require a ballast or transformer. As well, they are dimmable and function well even if exposed to heat or moisture. Incandescent lamps are also appreciated for their low initial cost and for their absence of toxic materials like mercury, toxic alloys or semiconductors, especially when disposing of lamps at the end of their life.
