IMT (Intelligent Mode Technology) Programmes

IMT defines the Gloworm ethos of versatility. IMT provides the freedom to use the Gloworm light in the default settings or to completely customise for ultimate personalisation.

Trail – Low>Medium>High.  Special mode>Super Dim (all programmable to the users requirements)

Commute – Low>High. Special mode>Flash (2Hz) (all programmable to the users requirements)

Special modes are activated by holding down the button for 2 sec.  This allows the user to conduct any outdoor activity without having to cycle through the special mode and having an interuption of a steady light beam.  Additionally, the XS is shut down by holding the button for appx 5sec.  IMT gives you the flexibility of refined programmes and modes without needing to access them every time you go from High mode back to low.

All output levels are user programable (see MANUAL for details) making this light highly versatile.
