T4P:
Great doug-gy!  ;D
It was interesting, who would have known he was working for the lighting industry  :o From last week's teardown i wouldn't have expected that

JoannaK:
Nice material there. Was expecting you two (three) to blow up something.. but perhaps on next video  ;D

nitro2k01:
Come on, open it up and scope the PWM signal! (Or if you have a light sensor like an LDR handy, scope it without opening it up.)

IanB:
About the closing remarks in the video: if you installed a panel like that as a lighting fixture in new construction, and after a few years it has faded and needs replacing, what would you do? Supposing an equivalent panel in the same form factor with the same mounting arrangements might not be available any more...

The big necessity with new lighting systems like that is going to be standardization. We have standard bayonet fittings (or Edison screw) for light bulbs and standard sizes for fluorescent tubes, ensuring universal drop-in replacements. LED technology will surely have to go the same way before it can become a mainstream lighting solution.
