What's the difference? Both seem to be CCFL rings. The inverter is a different brand. This one looks like it has filters on the outputs.

the main difference is the aluminum backing which will prevent the light to reflect back to the bulb housing reflectors. without that it would look like the housing is lit, sort of like city lights. but with these all the light is directed forward so all u see is the rings. understand ppl.
