there were some great things and some not so about it. the two sessions i went to (osram on leds and ti on led drivers) were somewhat opposites.
osram didn't get very much into anything i didn't know dealing in passing with leds for illumination, and they actually got a few things incorrect for lighting with leds. they were a little scattered in terms of getting info out, some bits were really interesting, but it felt a little intro to our product line rather than useful product info. i'd have liked more development roadmap and explanation of why they were using near phosphors vs deposited vs close remote phosphors and the implications of those on cost and efficiency, and a more accurate explanation of thermal issues and junction temperature not being "operating temperature"
the drivers thing was better, but a bit above my head for circuit design, i think it could have communicated more by discussing more of what leds need and the direct pros and cons of various power sources, and dealing with them, rather than too small circuit layouts on PPT. imho if you knew what certain terms were, you probably didn't' need the circuit layout, but if you didn't it was too small to read. folks seemed to either know lots about it and be making asides (which were educational themselves) or asking questions that showed some lack of understanding of what was being explained (not on topic, vs asking for clarity)
the vegetarian lunch selection was lousy, but the ceasar was passable and the company was excellent. i left 5 minutes into the keynote speaker when he hadn't said anything yet, since i couldn't justify any of the afternoon sessions as work related.
got a few samples from osram, and a widget i'm not sure what it is, and a thumb drive.
for those of you who didn't/couldn't make it in theory the presentations are all on a DVD we got, although i haven't looked to see if it's just the slides, or there's written/spoken content too.
