Pro: The ThruNite met my expectations generally. The headlight range is impressive, the Anstuerung the individual light levels via magnetic ring works very well, the individual steps will snap clean. Good, I like that the "Strobo mode" can be selected directly from standby. The terms are as stated, the lamp can easily be permanently operated in turbo mode. Cons: Unfortunately, the battery cage can be (charged with ThruNite batteries) promoted with great force in the lamp body. The LED is a brown spot that can be seen very well by the high magnification in large Refletor the TN 31. The photo is not affected, in my opinion. Tip: The operation with CR 123 batteries is far too expensive in the long run. It is advisable to operate the lamp with 18650 batteries. This should, however, previously made on security-related issues in the operation of knowledge with the batteries.
