New tools are often nothing special. Most of the time they are incremental updates, but occasionally, they alter the makeup of an existing idea enough to be considered original – like the one-handed reciprocating saw, for example. But other times, they are downright original. I mean, truly original – as in “the first of its kind”. Milwaukee pulled this off when it saw a need for identifying and fixing fluorescent lighting. There simply wasn’t a meter on the market that could troubleshoot and fix this style of lighting quickly and easily. What the new Milwaukee 2210-20 Fluorescent Lighting Tester does is allow maintenance professionals to extend a probe, turn to the lamp function, press the test function and check to see if the lamp is good or bad. But how? The meter emits high frequency voltage when it contacts the glass. This process “activates” the bulb because the rod acts as a ballast which will energize a good lamp.
