Research continues to improve the efficiency of newer models of LED street lights (modernizing with LED street lights). However, LED street lighting is not as efficient as low-pressure sodium (SOX) street lighting in the United Kingdom. [clarification needed] An LED street light based on a 901-milliwatt output LED can normally produce the same ...
"43" LED sticker—43 watts—Very common "46" LED sticker—46 watts—Very common; A label with a PS before the MH (e.g. 17 PSMH) on a MH sticker indicates that the fixture utilizes the newer pulse start technology, which uses different lamps than the older probe start technology. [1] [2] New Nema LED Sticker Uses For Led Street Light
The ongoing global switch from (mainly) orange high pressure sodium lamps for street lighting to (mainly) white LEDs has resulted in a shift towards broad spectrum light, with greater short wavelength (blue) emissions. [7] This switch is problematic from the perspective of increased astronomical and ecological light pollution.
The other is to use a phosphor material to convert monochromatic light from a blue or UV LED to broad-spectrum white light, similar to a fluorescent lamp. The yellow phosphor is cerium-doped YAG crystals suspended in the package or coated on the LED. This YAG phosphor causes white LEDs to appear yellow when off, and the space between the ...

The spectrum of a standard illuminant, like any other profile of light, can be converted into tristimulus values. The set of three tristimulus coordinates of an illuminant is called a white point. If the profile is normalized, then the white point can equivalently be expressed as a pair of chromaticity coordinates.
