Product Overviews

PWI expertise lies in lighting and coil winding, including specialized magnetometers. We also have contract manufacturing and engineering services.


Aviation Lighting

PWI has been in the Aviation Lighting business since 1972. We can make customized cold cathode fluorescent lamps to any specification and also carry a full line of LED lights from LED reading bulbs to full LED upgrade kits for your existing CCFL systems. We offer a line of hot cathode fluorescent lighting as well.


Tape-wound bobbin cores can be used in special low-frequency transformer and inductor designs, magnetometers, and current-sensing transformers. These cores are utilized in applications where core memory is important. PWI’s tape-wound cores are unique in their core memory due to their switching speed and magnetic memory characteristics that are achieved in our manufacturing processes.
