This is a review of the ThruNite TH20 Headlamp. The light was sent to me by ThruNite in return for my review , as always I give my honest opinion of the lights I review. Amazon Link for light HERE
First I did not mention in the video that this light has a “lock out” by turning the end cap 1/16 to 1/8 of a turn to prevent any accidental switching on. Also I wanted to say that one handed operation is NOT a problem when wearing the headlamp.
This is my first headlamp with any kind of quality , as all the others I have are the 4 or 5 dollar department store variety. The TH20 is a very solidly built light with nice anodizing and machining both. The headband is comfortable and the light stays in place well. You simply turn the light a bit in the holder to adjust it up or down more. I really like the Ramping or “infinity” firmware , as you can go to any brightness level , with NO predefined modes. The light also has mode memory , so it comes back on at whatever level you choose when the light is turned off and back on later. The “firefly” mode to me is just the right brightness , but that is my personal preference and may be more than some like.
Overall I am really liking the TH20 and for just under $30 I think it is a good buy for a nice quality light…
The rest is covered in the video , again please note that my cheap video camera DOES NOT show nearly as true to life as the still photos in the slide portion of the video , as to what your eyes see.
