Our results suggest that spectral tuning of LEDs can affect the attraction of insects belonging to various orders, including Coleoptera and Hemiptera, although we did not find a significant difference between the two LED types with respect to the attraction of moths or flies. These findings ...
The energy savings of LED lights can be huge. Assume that a traffic light uses 100-watt bulbs today. The light is on 24 hours a day, so it uses 2.4 kilowatt-hours per day. If you assume power costs 8 cents per kilowatt-hour, it means that one traffic signal costs about 20 cents ...
Replacing an LED Light Prerequisites An LED light (maximum power: 15 W; type: LED) needs to be replaced. A spare LED light of the same model is available and functional. Procedure On the home screen of the display module, tapShutdownand turn off the device switch in the PDF. ...

Basically, the application will be in projecting random dithered structured light patterns, and requires a relatively high radiant flux (>=10W). Wavelength doesn't matter (can be anywhere between 400nm and 800nm). It would be awfully convenient to have th...
In previous studies, carbon dots were limited to the emission of lights such as blue and green. The new nanomaterial that Qu's team has developed can emit all light visible to the human eye, which is a breakthrough in the field of fluorescent carbon nanomaterial. ...

Electricity passed through mercury vapor in a fluorescent lamp produces short-wave ultraviolet light, which then causes the phosphor in the tube to fluoresce, making visible light. Mercury poisoning can result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury...
I've always been a cream highlighter kind of gal — but recently, since I haven't felt like adding another step to my routine, I've been loving using Nars' Tinted Glow Booster in medium to get that same lit-from-within glow.
