[edit] nice work, recommend citing sources

Houdini,

When I first read the new article, I thought it was strongly POV, and would need some significant edits to be encyclopedic style. But the edits over the last day or so made a big difference. I find the article much better balanced now.

One thing that would add a lot to the article would be citations for as many as possible of the performance landmarks or predictions for the future (e.g. "will be introduced in most homes by 2020" as in the LED article)

[edit] When?

Just wondering what is the time frame on SSLs will be hitting the market on the large scale? I've heard 2020 yet that seems a little bit too conservative. Anyone know? Caleb rosenberg 01:46, 3 April 2006 (UTC)

[edit] Article needs updating (future is now)

White diodes were developed by reasearchers in the last few years (in contrast to the last paragraph in the article), light fixtures are currently available for consumers.

[edit] Strange wording

It is the newest lighting technology to emerge in over 40 years is a bit of an odd sentence. If it's the newest in over 40 years then surely it's also the newest in 17384 years or whatever. What is the author tring to say here? EdDavies 21:57, 17 April 2006 (UTC)

I believe what's meant is it's the first new lighting technology to emerge in over 40 years. I've changed it to reflect that. TomTheHand 17:35, 17 May 2006 (UTC)

[edit] Life of incandescent bulb

I believe using the world record for longest bulb life to indicate the life of an incandescent bulb is inappropriate. Does anyone have any figures for typical incandescent bulb life? TomTheHand 17:35, 17 May 2006 (UTC)

Commercial, non-long-life, conventional incandescent lamps all seem to be rated in the range of 750 to 1000 hours. Quartz-halogen lamps seem to be rated at about 2000 hours on average. (And I'm sure you understand that these numbers are all deliberate design trade-offs between life and energy efficiency/color temperature so...) Long-life incandescent lamps range up to arbitrary values.

I went ahead and reverted the table back to its original state before it was filled with cherry-picked marketing and world records. I think this is best, as it was intended to be a comparison of typically available items. TomTheHand 17:49, 17 May 2006 (UTC)
Note that I'm not opposed to an updated table, but I don't think the previous update was done well. I'm also somewhat opposed to making selective edits to a table that a source (in this case, Sandia National Laboratories) created and that we're using in full. TomTheHand

[edit] Missing Environment section

no mercury, some phosfor, there seems to be a way to fabricate the leds without phosfor as wel. Mion 13:47, 7 March 2007 (UTC)

[edit] to led lamp

i'm moving the Led lamp info to its own article. Mion 23:27, 16 March 2007 (UTC)

Why? These two articles Solid-state lighting and LED lamp appear to be about the same thing - is there a solid-state lamp that isn't some kind of diode? Should be merged again, it would make the LED lamp article better to have this material there. --Wtshymanski (talk) 18:55, 26 February 2008 (UTC)
yes, solid state lighting is LED , OLED and PLED, why would you want to merge it into only 1 article ? merge it into all 3 then. Mion (talk) 20:22, 28 February 2008 (UTC)
Well, OLED and PLED are the same article and could be linked from LED lamp, if they are in fact used for lighting and not graphic displays. Solid-state lighting and LED lamp should be the same article, though - with links to LED, and OLED where necessary. --Wtshymanski (talk) 00:38, 29 February 2008 (UTC)
No, LED is per definition a solid state lighting, but NOT the other way around, solid state lighting could be LED or OLED, thats why you can't merge it. Cheers. Mion (talk) 14:06, 29 February 2008 (UTC)
But an OLED is just a kind of LED. --Wtshymanski (talk) 19:01, 29 February 2008 (UTC)
An OLED is a type of solid state lighting, just like LED, its not the same as LED. Cheers. Mion (talk) 07:26, 2 March 2008 (UTC)
