Every JDLITE flashlight is constructed from light weight, high strength aero-grade aluminium alloy. Additionally, the majority of JDLITE models are CNC machined from a solid aluminium bar which gives our flashlights their superior shock/impact resistance, with many lights able to withstand being rolled over by car or dropped from several meters onto a hard surface with no performance loss. Furthermore, all JDLITE models are treated with a military-spec type III hard anodized finish, making the flashlight surface as tough as diamond, thus protecting it from scratches, abrasions and corrosion.
