The NiteCore Tube is a very handy rechargeable keychain LED. Sized like a car key, you barely notice carrying it with you. The torch is equipped with an integrated Li-ion battery. It is easy to charge through USB. So you never have to change the batteries. The housing is made of high value polycarbonate, the same type of which sports helmets, DVDs and products for aviation are made. This makes the lamp waterproof and dustproof according to IP65 standard and it can withstand a drop of up to 1.5 meters.
In lowest mode, this torch offers 1 lumen. When the torch is in this mode, you can hold down the switch on the top of the lamp. That way you can increase the light output continually up to the maximum output of 45 lumens. By just pressing the switch twice, you directly get the highest mode.
The torch can be charged using a micro-USB cable. You find this connection on basically all cell phones (except iPhones).
2 light modes and continually adjustable:
- Low (1 ANSI lumen, 48 h)
- High (45 ANSI lumens, 1 h)
* The indication of the light intensity is according to the ANSI/NEMA FL 1-2009 standards. This means that the values may be lower than former values . Naturally, this lower value has no consequence for the light intensity of the torch. The advantage of the ANSI/NEMA FL 1-2009 standards is that the values can be compared with each other and give a real picture of the actual light intenstiy.
