Multi-Bulb Magnetic Test Light
I used to make test lights out of various bulbs for load testing. Some bulbs obviously can produce some serious heat, and needed a shield to stop the bulb from possibly burning things, as well as to protect it from breaking. I used to like using glass mason jars. Those of you following my social media have likely seen them years ago.
So, as there are various headlight style load test lamps available, I wanted to offer you something a bit different.
This unit has a 194 bulb pigtail which happens to accept multiple bulbs of different wattage. For instance, the included 194 bulb draws 325mA. But, if you wanted something with a bit more, you could install one of the many different bulbs that fits this socket! A 921 bulb, for instance, would be at about 1.2amps!
You see how this single test light can be very useful. But it gets better. The unit is equipped with stackable banana ends. This means you can hook up your meter in line, and you can even use multiple units to create a higher current for load testing. .i.e 2 of these lights, with 921 bulbs would be at about 2.4 amps. This gives you many options and the best part is these bulbs will not produce the amount of heat that a larger halogen lamp style will.
I have drop tested these units (No pun intended) and they hold up quite well. They are a bit flexible, so they will not shatter if they hit the floor.
Oh yea, one more thing. These units are all standard with magnets! I don't need to explain how useful that is.
All units are transparent. Multiple colors available.
