[Q]: In September 2003, a new type of blue LED was demonstrated by Cree that consumes 24 mW at 20 milliamperes (mA). This produced a commercially packaged white light giving 65 lm/W at 20 mA, becoming the brightest white LED commercially available at the time, and more than four times as efficient as standard incandescents. In 2006, they demonstrated a prototype with a record white LED luminous efficacy of 131 lm/W at 20 mA. Nichia Corporation has developed a white LED with luminous efficacy of 150 lm/W at a forward current of 20 mA. Cree's XLamp XM-L LEDs, commercially available in 2011, produce 100 lm/W at their full power of 10 W, and up to 160 lm/W at around 2 W input power. In 2012, Cree announced a white LED giving 254 lm/W, and 303 lm/W in March 2014. Practical general lighting needs high-power LEDs, of one watt or more. Typical operating currents for such devices begin at 350 mA.
[A]: In what year was a new type of blue LED produced?


[Q]: Nicholas Lezard described post-punk as "a fusion of art and music". The era saw the robust appropriation of ideas from literature, art, cinema, philosophy, politics and critical theory into musical and pop cultural contexts. Artists sought to refuse the common distinction between high and low culture and returned to the art school tradition found in the work of artists such as Captain Beefheart and David Bowie. Among major influences on a variety of post-punk artists were writers such as William S. Burroughs and J.G. Ballard, avant-garde political scenes such as Situationism and Dada, and intellectual movements such as postmodernism. Many artists viewed their work in explicitly political terms. Additionally, in some locations, the creation of post-punk music was closely linked to the development of efficacious subcultures, which played important roles in the production of art, multimedia performances, fanzines and independent labels related to the music. Many post-punk artists maintained an anti-corporatist approach to recording and instead seized on alternate means of producing and releasing music. Journalists also became an important element of the culture, and popular music magazines and critics became immersed in the movement.
[A]: How did Nicholas Lezard describe post-punk?


[Q]: The culture of Eritrea has been largely shaped by the country's location on the Red Sea coast. One of the most recognizable parts of Eritrean culture is the coffee ceremony. Coffee (Ge'ez ቡን būn) is offered when visiting friends, during festivities, or as a daily staple of life. During the coffee ceremony, there are traditions that are upheld. The coffee is served in three rounds: the first brew or round is called awel in Tigrinya meaning first, the second round is called kalaay meaning second, and the third round is called bereka meaning "to be blessed". If coffee is politely declined, then most likely tea ("shai" ሻሂ shahee) will instead be served.
[A]:
What geographical location in Eritrea has largely shaped the culture of Eritrea?
