R&D News: Firefly-inspired LEDs

Personal Interest Background  As of late, I have been fascinated by LED light technology because this technology has the potential to drastically reduce energy consumption for lighting solutions. In this quest for more efficient lighting, I found 40W replacement LED lights that use only 6 Watts while producing 400 lumens equivalent to a 66.6 lumens/W. That's not bad considering that an equivalent CFL consumes at least 9 Watts which equals a 44.4 lumens/W. The cutting edge of technology commercially available can be seen in the Phillips L-Prize LED 60 W replacement LED light which produces 940 lumens with only 10W (94 lumens/W!!!). For comparison, CFLs at this range have an efficiency of roughly 61.3 lumens/W. It appears that LED technology still has room to improve which it must to produce lighting solutions at the 100W replacement range. Companies like Osram, GE or Phillips have all announced their first entrance into these market segments. However, the consumption ranges from 2
