Bermuda has developed a proud Rugby Union community. The Bermuda Rugby Union team won the 2011 Caribbean championships, defeating Guyana in the final. They previously beat The Bahamas and Mexico to take the crown. Rugby 7's is also played, with four rounds scheduled to take place in the 2011–2012 season. The Bermuda 7's team competed in the 2011 Las Vegas 7's, defeating the Mexican team. There are four clubs on the island: (1) Police (2) Mariners (3) Teachers (4) Renegades. There is a men's and women's competition–current league champions are Police (Men) (winning the title for the first time since the 1990s) and Renegades (women's). Games are currently played at Warwick Academy. Bermuda u/19 team won the 2010 Caribbean Championships.
Who won the 2011 Caribbean championships?

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.
In what year was a new type of blue LED produced?

During World War II, Imperial Japan invaded most of the former western colonies. The Shōwa occupation regime committed violent actions against civilians such as the Manila massacre and the implementation of a system of forced labour, such as the one involving 4 to 10 million romusha in Indonesia. A later UN report stated that four million people died in Indonesia as a result of famine and forced labour during the Japanese occupation. The Allied powers who defeated Japan in the South-East Asian theatre of World War II then contended with nationalists to whom the occupation authorities had granted independence.

The western colonies were invaded by whom during World War II?
