• 3 power levels - extends battery life
• Fast and slow strobe - extend battery life in emergency situations
• Find in the dark flashing LED
• On demand illumination - press and release push-button operation (without changing lens focus)
• Auto-off (14.5 mins) - prevents accidental drainage

NB: If you are intending to use this with the new Maglite AA LED torch, you will need to extend the contact spring slightly, as it does not quite make contact with the batteries. Thus, this product is a much better fit with a conventional Maglite.
