The effects of non-sinusoidal wave forms on incandescent lamp characteristics
… objectives: (1) To determine the variation of lamp characteristics with life for various wave forms. (2) To determine the variation of lamp characteristics with voltage for various wave forms. (3) To attempt to correlate the variation of lamp characteristics to the crest factor of the voltage …

Windmill electric plants
Owing to the recent development of the Tungsten incandescent lamp, which consumes 1 to 1 1/2 watts per candle-power and which has a positive temperature co-efficient, the windmill electric plant has very much greater possibilities to-day than when the carbon lamp was the only small electric light.

Three Dimensional Passive Integrated Electronic Ballast for Low Wattage HID Lamps
… is attributable to lighting. After the first incandescent lamp was invented in 1879, more and more energy efficient lighting devices, such as gas discharge lamps, and light-emitting diodes (LED), have been developed during the last century. It is estimated that over 38% of future global …

The role of the reference source in improving the CIE colour-rendering index for visual perception optimisation
… The reference source consists of an established incandescent lamp. The test source was assembled using four LEDs with wavelengths spanning the photometric spectrum fairly evenly. Recent studies have shown that the anatomy and physiology of the human eye is more complex than formerly accepted. …
