Overview & First Impressions
A sewer and storm crew works two shifts that barely overlap with daylight. Camera crawlers are set into manholes, cable is pulled, gaskets are cut, cones are placed and trace dye is checked at the outfall. All of it needs light, and some of it needs ultraviolet light to reveal dye or leak trace. A pocket light with a white main beam and a UV secondary is a genuinely useful tool for that shift, and EDC knives handle the cutting and trimming.
Materials & Construction
The Jetbeam E26 KUNAI UV is a rechargeable light rated at 2000 lumens with a secondary ultraviolet emitter and USB-C charging. Jetbeam flashlights build it in a slim body with a tail switch, so it can sit in a coverall pocket beside a folded blade. A white beam lights a manhole and a UV mode shows a dye trace on concrete where a white beam shows nothing at all.
Design & Details
Underground work is rough on gear. A light needs a bezel that can be dropped on concrete, a switch that works through a work glove and a body that can be wiped down with disinfectant at the end of a shift. The knife is chosen the same way: a liner lock that opens with one hand and a blade that can be removed from a pocket and rinsed.
Real-World Use
In one night the light illuminates a manhole ring, then drops to UV to confirm a dye trace at a storm outfall. The knife cuts a section of pull cord, trims a gasket to fit a frame, opens a bag of marking flags, slices shrink wrap off a camera crawler and trims the tape on a cone stack in the truck bed.
Ownership Notes
Utility tools should come out of a shift clean enough to inspect. Wipe the light housing with a disinfecting wipe, check the seams for moisture and charge it in a dry cab rather than a damp bin. Rinse the blade, dry the pivot and oil the lock face lightly. EdcMall carries the multi-mode lights and folders that suit underground crews, and a second light in the cab is standard practice. The same kit deserves a spare EDC flashlight in the truck, because a dye trace confirmed at one outfall still leaves four more to walk before the shift ends, and a light that dies mid-route costs a crew more than a second unit ever will.
Who Is This For?
This is for sewer and storm crews, camera inspection technicians and municipal maintenance staff who work at night. A homeowner inspecting a drain once does not need UV. If dye trace and dark chambers are part of your shift, buy a light with both modes and keep the folder simple.
Final Verdict
Two modes in one body is the whole argument for a UV EDC light on an inspection crew. White for the work, UV for the trace, and a liner lock folder for the cutting in between.
