I don't know how to cite stuff, but found above link. Tim S

The above comment is not dated, and so is not being checked by the archive bot as to age so it can ever move to the Talk page archive. Adding this comment so it will eventually get picked up and archived. Cheers. N2e (talk) 03:54, 23 August 2013 (UTC)

New generation white LEDs, more than 110 lm/W commercially available now[edit]

It's been quite an interesting year for the white LED industry, with mayor players trying to catch up among them, and significantly improving efficiencies in the meanwhile. There are already available "cool white" parts with efficiencies over 120 lm/W, and several manufacturers with even better chips down the pipeline. See, for example, the following data sheets:

http://www.lumileds.com/pdfs/DS56.pdf

http://www.seoulsemicon.co.kr/_homepage/home_kor/product/spec/W4218X.pdf

All of the above parts are commercially available from many sources, and already integrated into end-user products.

Efficiency[edit]

I think there should be some information on the efficiency of LED lamps. --Mortense (talk) 07:36, 8 May 2014 (UTC)

There is. Searching the article for 'efficien', I just found 24 occurrences of the words efficiency and efficient in the text, excluding the references section. Do you have any WP:RS new sources that have information we don't already cover? Also remember that 'efficiency' is quite hard to define for a light source, given the human eye's response to different wavelengths of light. The easier term to define, which much of the literature prefers, is luminous efficacy. --Nigelj (talk) 09:49, 8 May 2014 (UTC)
