The dust explains the longer-term dimming
events, but they don't full explain the shorter-term events.
Although it is generally recognized that LEDs are inherently dimmable and controllable, it is much more difficult to get the same results dimming
LEDs as those expected with incandescent bulbs.
phenomenon appears linked with the spread of urban areas and industrial activity, as reflected in data from across the country.
Wide power-input range and high power output make the dimming
technology available for various LED lamps.

lights will save pounds 147,000 a year
Whether or not to try to reduce global dimming
in a fast-warming world is a conundrum.
systems can satisfy the visual needs of the space, change light levels without disrupting operations, support worker satisfaction with personal control, and reduce utility costs through daylight harvesting, demand reduction, scheduled dimming
, and other strategies.
LED products reduces the light output but doesnt change the color as it does when dimming
standard incandescent sources, said Glenn Siegel, director, marketing and product management, Eatons Lighting Division.
However, the fact is that successful, highly-compatible and issue-free LED lighting installations are absolutely achievable in today's market if you understand how and when to use the various dimming
methods available and both utilize and appreciate the value of high-performance dimming
the lights in Cardiff will cause more accidents ("And the lights go dim", Echo, February 11).
Fairchild introduced the FL7730 single-stage primary side regulation (PSR) controller with power factor correction (PFC), TRIAC, and analog dimming
compatibility, as well as the FL7732 for non-dimming
Radiation reaching the ground at many locations declined significantly from the 1950s to the 1980s, a trend that some scientists have dubbed global dimming
