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.

Why are LEDs so much more efficient than incandescent light bulbs? Do LEDs have disadvantages? These are some of the questions I answer in this video about light bulbs. I also test the claimed wattage and find some anomalies... Proper English subtitles coming soon (tomorrow...)

This is a very simple project to make an adaptor that lets you run parallel strings of LEDs from USB power supplies and power banks. The types of string it can run are the parallel wired strings often found with solar powered strings or the battery powered strings. If you use the newer "effect" strings where alternate LEDs are wired in inverse parallel then only half will light depending on which way you plug it in. The circuit is designed to run the LEDs at a nice low level for efficiency and to maximise the lifespan of the LEDs. This also allows even a basic USB power bank to run a set for a very long time. Note that the cheaper power banks do not have proper low battery cut-off, so if the LEDs suddenly go dim then that's the time to unplug them and recharge the power bank. With bet...

Having already shown the horribly flickery LED globe lamp I thought it would be interesting to take a look inside the base. Latterly I was tempted to add a smoothing capacitor, but realise that the small ceramic capacitor may be relying on the high voltage drop across the array of LEDs, and adding a cap would suddenly mean that it was exposed to a much higher voltage at switch-on with the fully discharged electrolytic capacitor. It really needs better circuitry.

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?
