CO mrwolfe http://www.physorg.com/news/2011-03-bridgelux-silicon-substrate-lumens-watt.html " It's not so much brightness as efficiency, or more accurately, efficacy. A 60W tungsten bulb has an efficacy of about 13 lm/W, a halogen has about 25 lm/w and a spiral fluorescent comes in at around 115 lm/W. Brightness will depend onthe number of watts you put in! So, at 1A this LED uses 3.25W and puts out about the same amount of light as a 35W bulb." so this "135 lumen per watt" is good right, it will provide slightly more light hours on a AA x2 battery pack torch or garden PV light for instance, and drain your mobile device slower as they seem to keep the pointless LED's on all the time for no good reason :P

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
