Spark started off not very long ago by making some very interesting headlamps. The headlamps include a clear and frosted lens, giving you the option of either a traditional focused or a more diffused beam. The 460NW has a neutral white/outdoor tint and the 500CW has a traditional cool white tint. Both models are using 18650 batteries and the XM-L LEDs, which will light up a wider area than the XP-G LEDs.
Please note that high quality 18650 batteries are required to access and maintain the turbo mode of this light. 2 CR123s will likely not power turbo mode and many the protection circuit of many protected 18650s will kick in when the light is switched to turbo. Two batteries that we have tested and confirmed to power the turbo mode are the Eagletac 3100 mAh 18650 and the AW 2900 mAh 18650.
