This light has a Prometheus Beta QR Electroless Nickel core that was fairly beaten up and gifted to me so I thought I would rebuild it with some copper.
The head has a copper slug and I made a QTC pill for the tail giving variable output and direct drive when tightened fully.
I decided to make some extra tail accessories. The original light come with the brass hanging attachment.
I made the clip and magnetic attachments. An interesting design using a coiled spring and grooves for retention.
Pocket Clip attachment.
Due to the removable nature of the clip it is really only suitable for clipping inside a shirt pocket etc.
