All part# note: the diameter of the fully illuminated lamp for each of the Flip-Flat models is 6.7" or 170mm, regardless of the model purchased. To accomodate the smaller 4" to 6" OTA's, a spacer is added to the mounting bracket which better centers the lamp over the OTA. For the larger OTA, the bracket is machined down and an oversized ring is added to block any stray light from interferring with the flat lamp.
