[1x Built-In] If your walking path or cycling path calls for a specific illumination,
the Nitecore HC35 USB Rechargeable LED Headlamp can provide exactly what you need, and do it very well. So many times the illumination in an area calls for very little illumination to keep from interfering with the work of others. In this case, the Nitecore can be powered down to just a few lumens. When you need a great deal of illumination, the Nitecore can be increased up to 2700 linens. With five different levels of illumination, the Nitecore can get the job done. Thanks to B&H for providing great products at a reasonable price.

[4x LED] Bright, long lasting, and excellent build quality.

[0.22 lb] Loved it. Love the fact I don't have to worry about changing batteries in the dark. The charge hold for the night. Easy to use, very effective.

[ 45 Hours] Great product that replaces my old NU32 (micro USB) and now everything charges via USB-C. I like the lights and intensity. Overall well built and lightweight enough to be bearable over time.

[4x LED] This lamp comes with three brightness levels of white light as well as a flashing red light and a constant red light.  Only one color can be used at a time. The lamp also tilts on the head band (has three levels of tilt from about 30 degrees to about 90 degrees).  There are separate on/off buttons for the red or the white lights. The red lights really are not useful for other than being a warning marker of for viewing things up close (such as during night photography) since while the white lights have four LED bulbs, the red lights only have one.



I have been using this item almost every day for about 10 weeks.  At first I was using the light at the brightest (of three) levels as I walked in the dark.  At this level the charge lasts about two hours.  After a while, I realized I didnt need to see 150 feet on front of me so switched to the middle level of brightness and while I could only see about 10 to 15 feet ahead of me this is more than most people will need and the charge lasts about 10 hours.  I havent really used the lowest brightness level much so I cant comment on how long the charge would last at that level.


One feature I really like about this lamp is that after you choose your brightness level you can turn the light off without having to cycle through all the other light levels. 



When I am walking the head-band keeps the light in the right location on my forehead without slipping and without being overly tight.   If you jog, however, I think that you should get a head band that includes a strap over the top of your head since I think this one will slip unless you make the elastic very tight.

[4 x 3.4 x 2"] If I had one complaint is that I do wish the unit could remain on turbo mode for longer without over heating. Battery life is excellent. Build quality is superior.

[1x Built-In] Well made, reliable, works

[1.5 Hours] So for it is excellent, build quality is very good, and it is very bright.
It serves my purpose well, just what I was hoping for, and let me not forget, great service from B&H, you are always on time. Thank you, looking forward to my next purchase.

[ 45 Hours] What's the quickest way to become persona non grata at a star party? Easy, just flash any kind of white light, even for a moment. That's what I appreciate about this lamp, a dedicated switch for red light, not a cycle of going through green light, then white (opps!), maybe an emergency signal as well, and finally red. The idea of charging the lamp with a USB connection wouldn't have been my first choice, but it's no big deal for me, and it's nice to know I'm going out into the dark with a fully-charged unit. This is a good choice for night photography if others are around.

[ 45 Hours] This light starts out dim and gets brighter with every press until it cycles back to dim. You hold the button for 2 seconds to turn it off. It's pretty straight-forward and it's a very good light.
I really like that it uses either 2 little 3V batteries or an inexpensive 18360 3.7v battery.
This light is tough, and it can be removed from the headband and set on a table or magnetically attached to any ferrous surface, so it's very versatile.
