Feng at Lite Systems is extremely helpful and his product is solid and reliable.
I recently bought an 8 foot flat panel LED light for an eventual 10 foot table.
The assembly is a bit of an effort because you are constructing the light from the ground up but Feng is there to help you with anything. He includes the steel wire to hang the light and will work with you on materials to wire the light correctly.
This is a solid and well made frame that goes together exactly as required upon assembly. My only recommendation is that if you do not have experience with the electrician side of things, hire a pro to correctly wire the LED panels together and then into your outlet.
Send me a PM, I have his current card so maybe you have different numbers/contact info.
