New generation white LEDs, more than 110 lm/W commercially available now
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:
All of the above parts are commercially available from many sources, and already integrated into end-user products.
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)
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)
Meaning no disrespect to the people who go to the trouble of taking and posting pictures, I do have some questions about the usefulness of a couple of them:
File:LED T-bar ceiling light.JPG , caption "Dropped ceiling with LED lamps": There is nothing evident in this photo that indicates LED lamps are being used. I could take a photo of a dropped ceiling with fixtures using 2x2 fluorescent tubes (or incandescent bulbs, or light pipes to a daylit sky) and it would not look any different. In fact, I could such a photo with a similar file name and caption to this one, claiming it to be LEDs, and nobody would be able to prove the lie... except perhaps by spectral analysis of the RGB data in the file. So... what does this photo add to the article?
File:LED-flickering.JPG , caption "Camera of mobile phone can detect flickering of LED light bulb": This photo at least needs the caption to describe exactly how it is detecting or showing flickering, and why the effect (whatever it is) is not some other artifact.
