Night Master extension tubes are used to extend the length of the lamps in order to fit an additional 18650 rechargeable battery. Doing this will give you a longer runtime and also a brighter beam as more voltage is being put through the LED. Extension tubes are available for our NM400, Venom Strike, NM800, NM800-IC and also a double battery tube is available for the Eclipse 800 torch.
