Sekonic multi-lumi Analog Light Meter in case, vintage model L-248. Made in Japan and distributed by Copal, it is an instrument used in photography and cinematography to measure light levels and determine the proper exposure settings for cameras. This is in vintage condition, we weren’t able to test it, and it may need a battery- thus the price has been lowered to reflect that. Some of these operate without the need for batteries, relying on a selenium photocell, but we don’t know 100% if this is one of those models. These sell on other resale sites and vintage stores for around $30-50+.
