High Pressure Sodium
The industry has recognised HPS as a standard due to its high efficacy and lumen maintenance. The largest issue with HPS lighting technology is the colour the light source emits, which appears to the human eye as orange and represents poor quality of light at night. Light source colour is measured by the colour rendering index (CRI) which was introduced in the 1940s as a way to benchmark electric light sources against natural light. At around the 30 range on the CRI scale, HPS lamps fall well below competitive technologies on a scale out of 100.
Under poor light source colouring objects do not appear as their natural colours, but rather all appear as a muddy shade of orange. This presents a significant risk in hazardous environments at night, since machine operators and maintenance workers need to quickly and easily identify coloured wires, safety plaques, liquids, objects or smoke.
Low Pressure Sodium
LPS is technically not a white light source but has been used in lighting. LPS has very high bulb efficacy (up to 200 lumens/watt) but has the worst colour quality with a CRI of about 5. The poor colour quality makes it a high-risk option where workers need to quickly and easily identify coloured wires, safety plaques, liquids, objects or smoke.
Mercury vapour
Mercury vapour is fairly inefficient with a bulb efficacy of about 50 lumens/watt (when phosphor coated) and has a poor CRI of up to about 50. The phosphor coating on the glass of the bulb makes it a large source size and therefore difficult to control the light distribution precisely. For these reasons, and due to the use of mercury, these lamps are not commonly used anymore. The source size is large due to the use of phosphors and therefore controlling the light distribution is difficult and can result in poor utilisation of light.
Metal halide
Metal halide is a common light source used today because of its good colour quality (85-95) and low cost. Metal halide suffers from rapid lumen depreciation. Metal halide lamps contain mercury.
Fluorescent
Fluorescent fixtures are also common light sources used today due to their high efficacy ( lumens/watt) and good colour rendering (50-90). Fluorescent bulbs have good lumen maintenance but fail catastrophically at end of life. Fluorescent lamps contain mercury. The source size is large due to the use of phosphors and therefore controlling the light distribution is difficult and can result in poor utilisation of light.
Compact fluorescent
Compact fluorescent (CCFL) bulbs have good CRIs (50-90) but mediocre efficacies (50-75 lumens/watt). Compact fluorescent lamps contain mercury. The source size is large due to the use of phosphors and therefore controlling the light distribution is difficult and can result in poor utilisation of light.
Incandescent
Incandescent lamps have the highest CRI (up to 100) but the lowest efficacies (5-25).
Induction
Induction lighting is similar to fluorescent but is an electrode-less bulb and therefore has long life (over 100,000 hours). It has good CRI (50-90) and good efficacy (60-90 lumens per watt). The source size is large due to the use of phosphors and therefore controlling the light distribution is difficult and can result in poor utilisation of light.
Light Emitting Plasma
Light emitting plasma is the newest light source technology. It uses an electrode-less bulb and therefore has long life (over 100,000 hours). It has good CRI (50-90) and good efficacy (60-90 lumens per watt).
LED
LEDs are “full-spectrum” light sources with no gaps in the colour spectrum. They have good CRI (70-85) and the highest efficacy (up to 160 lumens/watt) of the white light sources. LEDs emit light in a hemispherical direction instead of a full spherical direction. Because the light is only directed forward, the optics can be simpler and are more efficient. LEDs can last well over 100,000 hours.
