This is a 19" diameter parabolic glass mirror. It is used in Perko 19" Solar-Ray® Searchlight models: 1901, 1902, and 1902DE4. Any curved lines visible in the images are artifacts of the photographic process; the reflective surface, itself, is just a smooth mirror.
Note: Note: A Reflector Clip Upgrade Kit for 1900 Series searchlights when replacing the reflector in an older Perko Series 1900 searchlight. This kit is sold separately; see Replacement Products, below.
You will need to provide the serial number on the outside of the seachlight drum to determine if your is an older style light. Call us at 1-800-426-6930 for assistance.
The set of retaining clips consists of 8 clips - 4 long, 4 short (to make 4 sets). You will need to re-use the original fasteners.
