The flashlight is one of the most used tools to an aircraft mechanic. Critical inspections require adequate lighting to get the job done properly. Not only mechanics working at night need a quality light but also day shifters as well. Day time and bright sunlight can cause shadows which can obscure the vision of the technician. Being able to shine a bright light into a darkened area is an important trait considering the light must overcome the ambient light to be effective.
Things to Avoid
1. Dim flashlights with not enough power. A powerful light with a enough power to overcome the bright ambient sunlight is critical for daytime inspections.
2. Poor quality. Cheap flashlights are great for the campground or the glove box but a professional mechanic needs a professional light. One that is built tough and testing in real-world conditions. Poorly machined parts mean water can pass though and ruin your light.
3. Expensive batteries that need constant replacement. Rechargeable batteries are all the rage these days because they cost less to operate and can be charged while not at work.
4.Non waterproof flashlights. Let's face it. Working in the rain or snow is part of the job. Poorly designed flashlights let water into their housing wreaking havoc on the internal parts causing failure. Check for IPX8 rating for waterpoofness, it's the highest rating available.
5. Heavy and bulky flashlights. Do you remember those D-cell mag lights? Those things were heavy and bulky. Chances are you're going to have your hands full with a bunch of other tools so having a lightweight torch you can stick in your pocket and not bother you is key.
