Seoul P4 is not 119lm@350mA !?

[chris_m]

NO. Please tell me (if you want to be believed) where you read that 119!

It's in the binning guide - straight off the site selling that LED http://www.leds.de/media/products/0349526001175432269.pdf

If it was more than 118.5 it would be a V-bin, not a U-bin.

Strictly speaking, by claiming 119 max rather than 118.5 max I think that would also fall foul of advertising regs in the UK.

"Color: white
Luminous Intensity: bei 350mA 119lm, bei 1000mA 240lm"
Viewing angle: 125°"

Where do you exactly see "Max" in this text?

Where's that text from? At the original link http://www.leds.de/product_info.php?info=p266_Seoul-Z-LED-P4-Star--wei---240-Lumen.html it says:

"Color white
Luminous intensity max. bei 350mA 119lm, bei 1000mA 240lm
Viewing angle 125°"

(cut and pasted straight from there - minor editing, but nothing added!)

Oh, now it's different than when I wrote my last message! I suspect that the version of that page oscillated during the last hours.
Perhaps it was the effect of the claim I sent to them yesterday

And the data sheet at http://www.seoulsemicon.co.kr/_homepage/home_kor/product/spec/W42180.pdf only reports the T and the U rank... I didn't find that other document on the Seoul site.

I shouldn't have been so hard on you - ISTR the same thing - they must have just changed it (and maybe you had a cached version). That binning note is on the Seoul site http://www.essc.co.kr/_HOMEPAGE/home_kor/product/spec/P4_BL.pdf under documentation near the top of http://www.seoulsemicon.co.kr/_homepage/home_kor/product/product_P4series.asp?topCODE=2&midCODE=4 (though I couldn't find it earlier as some of the Seoul site gets blocked in work).

Oh, now I understand why I didn't find it by searching it with Google with the key "site:seoulsemicon.co.kr"

Yeah, I was trying much the same thing, and having much the same problem due to the Seoul site not working properly in work. BTW are you using Firefox, since it's never worked properly under that? You have to downgrade to IE

I'm using IE7 under XP and Vista and the english version of their site is always broken (tried in the last days): I get a window dialog with an error and the frame under the subject remains blank.
This is why I searched from Google...

I have a feeling newer versions of IE may also be a problem - doesn't seem to be just the blocking that's a problem in work with IE. Works fine with IE6 here (one of the few reasons I use it is to check out the Seoul site).
