Mach Sakai does a comparative review of two headlamps from brands that are already familiar with airsoft players, ThruNite and WowTac. This is the first comparison we have seen so far of the ThruNite TH30 and the WowTac AS2 Headlamps, which is useful for using at night or even for teching when you need a headlamp to look for those tiny parts you need when repairing an airsoft gun.
