A simple, low cost, conversion of incandescent-lamp illuminator to a power LED By Dushan Grujich, on October 15th. 2012 My LOMO Biolam 70 has e with the OI-32 illuminator using a 220V AC 15W incandescent-lamp, which, when used for longer period gets very hot to the touch. This situation had me thinking of replacing incandescent-lamp with a power LED.
