Reversed edit
I reversed your edit to Candela. The definition you changed was a direct quote of the official definition of the unit. Direct quotations have to be kept exact. The explanation in plain English, with the wavelength in nm, is three paragraphs further down in the article, under the heading "Explanation"--Srleffler (talk) 03:06, 15 July 2008 (UTC)
