A: Hi Curious not sure about the Grafik Eye dimmer system as have never used but sure Lutron dimmers will work, I have mine Halco LED 8 watt br30 on a Lutron Model #MACL-153MHW-WH Maestro dimmer and they work great and dim as they should. If you have the Grafik Eye system would just try the bulbs and you can call Lutron at 1-800-523-9466 so see if they have tested out the bulbs.
A: Thank you for the inquiry. These bulbs are manufactured in China.
A: HI PGHGUY, well just like most stuff are made in China.
