This Compound Semiconductor article, HB-LED industry in ‘dire need’ of uniform standards, raises some very pertinent issues about consumer acceptance of solid state lighting. The makers of High-brightness LEDS (HB-LEDs in the article)

“Some experiments have indicated that human perception and liking for shades of white does not conform to the CRI,” says the report. “In fact, an experiment suggests that our liking for warm or cold white light varies according to the time of day and the ambient conditions.”

Yes, standardization would help this emerging market. This article is full of good advice for those firms attempting to bring solid-state lighting products to market.
