Electronic Technician Toolkit Incandescence Light Bulb Current Limiter A must have for any electronic technician! It helps save fuses, makes troubleshooting easier and all around a handy device to keep on your work bench! It does not come with a light bulb. It is recommended that you use a 100 watt incandescent light bulb. That will give you 1 amp of current limiting. The way it works: you plug your Unit Under Test into the load socket, plug in the AC cord from the current limiter into the wall and flip the switch. When you turn your unit on, if the light bulb lights up brightly, it means you have a problem and need to fix it. If it does not light up or is very dim, then the unit may have another issue or may very well have no issue at all! Show more
