A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode, which emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.
An LED is often small in area (less than 1 mm2) and integrated optical components may be used to shape its radiation pattern.
Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.

I'm not sure of the seller of this LED mislead me by telling me it was for UK 240V electric, but when I tigged on the solders it banged really loud. I do not recommend bying LEDs from bad people becauise they go boom and may scare you. And for those who actually read down to this level... The actual result of hooking a (really crappy) 100W LED directly across 240V was so boringly controlled that I had to beef it up a bit for a second take with hidden resistors underneath for some sparks and pops. See if you can spot them as I completely lose control of the LED at least twice during the video. No good quality LEDs were harmed in the making of this video. Mainly because I can't get any.

http://democracynow.org - The fight to retake the last stronghold of the self-proclaimed Islamic State in Iraq has entered its third day with a U.S.-led coalition force of about 30,000 that includes Iraqi security personnel, Kurdish fighters, Sunni Muslim Arab tribesmen and Shia Muslim paramilitaries. The Pentagon says U.S. special forces are on the ground in Iraq and taking part in the battle, despite President Obama’s pledge against having boots on the ground. They face an estimated 5,000 Islamic State fighters in and around Mosul. Meanwhile, humanitarian workers say some 200,000 people may need shelter during the offensive. We speak with Patrick Cockburn, Middle East correspondent for The Independent, where he writes that Mosul is bracing for its next bloody chapter after being ravaged...

http://brs.li/BRS160_Week21 It's Week 21 of 52 Weeks of Reefing, and this week we are premiering the highly anticipated LED lighting video. This is the week you have been waiting for: LEDs. We are going to start with the general pros and cons including why so many reefers have gravitated to LED’s over the years, evaluate LED in general based on the same criteria we used on T5 and halides, discuss what you should look for in a LED option, and breakdown of some of the most popular options and finish with how to tune your LED’s PAR, spectrum and shimmer. So follow along, and be sure to let us know about your favorite lighting in the comments area down below! Thanks for watching, and stay tuned for next week's video where we uncover which lighting system we chose for the BRS160. *Legal...

call it a day, nothing to say
maybe it's easy that way
i don't know - you never did
i don't know - let it go
nothing to say, but it's ok
maybe you want it this way
haven't you led me long enough to throw me a bone?
haven't you bled me long enough to live on your own?
call it a day, lust made us grey
i'll always see you that way
send me away, 'cause i wouldn't stay
never lived here anyway
haven't you led me long enough to throw me a bone?
