I was disapointed myself with alot of it: I was un impressed with the Chinese offerings, I saw plenty of snow cone styled A lamps, and LED par lamps with designs and materials from 5 years ago. HeliPad lighting?, plastic lamp changers?, very little OLEDs products. Alot of the products lacked when really vigorously/ carefully evaluated- and people manning the boothes who couldn't speak to queries about drive current or chips used - it made me think alot of the exhibitors were borderline concerns, many won't be around in 4 yrs/an equal number were not germaine to me - induction lighting, LED tape or Tubes etc. I don't know if you were looking for opinions on the seminars but the 2 I went to were not a good value for the cost. I did like the Philips and Traxxon exhibits and I really liked Philly as a location. - But it lacked industry leader attendance I was hoping for- and I was disapointed by the unwillingness of attendees to put down their smart phones and speak face to face to colleagues and counterparts!
