Nitecore HC75 UHE 3000 Lumen USB-C Rechargeable Zoomable Work Headlamp

For the most part I like the headlamp. I like how I can change from flood to spot light. Just two things that keep me from giving it 5 stars. 1) if I want to change the brightness after the headlamp is on, the headlamp just turns right off and I have to turn it on and cycle through the light brightness. 2) going off the 1st issue, once it turned on it doesn't remember the last setting you had it on. So again you have the cycle through and adjust the sweet spot that you had it between flood and spot.

Very bright and comfortable several light settings has a zoom and flood setting which is really interesting to use and a red light setting. It's a little heavy on your head but I think you would get used to it over time and if it was on hard hat of some sort you probably wouldn't notice it much at all. It's seems to be made with Top Notch quality which is common with nightcore flashlights. With some very low light settings that I'm sure would make the battery last a long time.

I discovered another (third) significant error with the HC75 UHE (see my earlier review from June 5th for the first two problems), which brings this headlamp down to a one-star rating. It has some major programming errors, and it never should have gotten through their quality control.

I actually discovered some more peculiar sequences within the special modes (SOS, beacon, and flashing red LEDs) that are a little too complex to succinctly write about, but the third major flaw with this headlamp is when you enter Special Modes while the red LEDs are on.

To begin from "off", long-pressing the Zoom button will turn the headlamp on with the red LEDs. Then, enter Special Modes by rapidly double-clicking the Zoom button. This will activate the SOS sequence. While the SOS is flashing, return to the previous state by again rapidly double-clicking the Zoom button. (There is no rush to get through all of these in a fixed time limit. These functions are all supposed to work this way.) When you’re back to the red LEDs, turn the headlamp off by clicking the Power button.

This is where things go wrong. The headlamp should now be in an “off” state, and you should be able to turn the headlamp back on to the normal white lights by clicking the Power button. If you click the Power button nothing will happen. Click the Power button a second time (NOT a rapid double-click) within about 3 seconds and the red LEDs will turn back on. This is not supposed to happen. At this point, the Power button will only turn the red LEDs back on if you slowly click it twice.

The ONLY way I’ve discovered to get back to the white lights from here is to quickly double-click the Power button when off, to activate the Ultralow setting of the headlamp. Then, you can turn the headlamp off at this point, and when you turn it back on it should start to function normally again.

I strongly recommend avoiding this headlamp completely. There are too many things wrong with it, and they should pull it from the shelves until these issues are fixed. Nitecore should offer refunds to the people who have already purchased it.

Peut être un peut lourd pour porter toute la journée pour le travail , mais le fuseau d''éclairage et l'autonomie sont impressionnante.

Does not seem to be 3000 lumens. But nice head lamp
