They linked the article that mentioned that 200 lumens/watt lamp (
http://www.treehugger.com/energy-efficiency/philips-shows-breakthrough-200-lumenswatt-warm-white-led-lamp.html http://www.treehugger.com/energy-efficiency/philips-shows-br... ), seems a replacement for fluorescent tubes.
Quote from that:
"[...] this new LED model achieves an impressive 200 lumens/watt while meeting the criteria required for comfortable workplace lighting (ie. a color temperature of 3000–4000 kelvins, a color rendering index of at least 80, and an R9 saturated red level of no less than 20). That's not the same as having a super-efficient LED that produces horrible light quality for the sake of breaking records."
Also: "expected to hit the market in 2015 for office and industry applications".
