Last weekend we extensivly compared our 2 different types of angel eyes. The outcome didn't surprise us very much. The LED angel eye is brighter and doesn't have the gap in the ring, the LED angel eye is more OEM white around 4300K. The CCFL is more like 6000K color temperature. The LED ring is more expensive and has a yellow coating (white version, amber version is white when turned off). Since the Led ring doesn't have a warm up time, it's also possible to use it as (an extension of) your turn signal. So compared: Led: * Brightest * OEM 4300K color * Instant full brightness * No gap - Yellow color when turned off (white version) CCFL * Cheaper * 6000K color temperature We made a video, with and without shroud. And the Led halo rings as turn signal.
