HP35R 4000 Lumen USB-C Rechargeable Headlamp, with Spotlight, Floodlight and red Light for Search and Rescue, Outdoor use, Emergencies, and More

An HR35R Review by a User Who Wore Out Its Predecessor, the HR30R v2 After 14 months of 10-hour workdays in color inspection, often in hazardous environmental conditions. --- Pluses of the HR35R: ** Best headlamp to date for real daily, serious job use [without building it yourself], with no serious competition. ** Awesome color rendering, at least in this year's model. ** Disciplined beam that exactly—and, more importantly, efficiently—matches the human eye's cones and rods. This makes the beam seem much, much brighter and finally allows us to get a full working day at serious brightness without stopping to change the batteries, even if you work over 12 or 13 hours, as I sometimes do. (Typically, 10 hours of runtime is needed.) ** Great battery source, which is state-of-the-art. ** 7.2V battery that allows a 92–95% efficient buck driver, unlike the standard 3.7V which can only become a 70% efficient CC driver of single-cell lights—meaning hours and hours of more runtime just because of the 20% driver juice savings. ** Comfortable enough and balanced on the head, which can't be said of any single-cell right-angle light. ** The chosen setting for spot and flood is well-tuned to avoid killing runtime while adding just enough flood to boost the deep warm colors and a tiny bit of brighter feeling. The spot already has lots of wide spill on its own. ** The battery pack cord is a standard 2.5x5mm and easy to make inexpensively. ** Fenix allegedly offers a 1-year warranty. ** It and its HR30R predecessor are the only headlamps with a shaped and disciplined flood—bright enough and with enough battery to back up the insane juice needed for flood. This makes the HR35R and its predecessor, the HR30R v2 (2S1850), the first flood headlamps I’ve used beyond walking to the bathroom since I started using LED headlamps in 2005. ** This headlamp has a rear back-of-the-head red light and would make the ultimate bike light for sure! ** No fire hazard with this year’s model’s flood, unlike the HR30R v2, whose TIR lenses burned into my bedsheets twice after I forgot to turn off the high flood and set it face-down while I ran into the bathroom for only a minute. No such danger in the HR35R. ** They don’t mention AR glass or high CRI, but it appears to have both features. ** Unlike the HR30R v2, the HR35R has a noticeable proximity sensor for turbo mode, which throttles if the light is too close—avoiding blinding and preventing accidental fires from the intense hotspot. ** Obviously, it’s well-built and thought out, with efficient drivers, heat sinking, glass lenses, etc. ** I verified the lux and lumens listed on the spec sheets. And so, I still trust the Fenix lux and lumen ratings, if not their disastrously incorrect spec sheet runtimes (at least on their 7.2V lights in the past few years). ** Oh, did I mention the disciplined beam, the beautiful color, and finally having a full bright workday without having to stop, clean up, travel to the base area, and change the battery? LOL. --- Downsides (that I hate to mention, because of the importance of the upsides): ** I really miss the separate control of the flood and spot that its predecessor had. This allowed more useful settings like a double low or mid flood plus low spot for runtime and better flood, as well as other mixing settings for better flood applications. ** Fenix should offer buyers a discounted option to buy a backup battery pack, even though the medium setting is 2x brighter than its predecessor and will get you through the day, unlike the HR30R v2. ** They should also offer a pack that fits our own 21700s, like the HR30R pack. ** You will either get years out of it or use it constantly and get your money back many times while wearing it out in something like 15 months. But, I didn’t get any response from Fenix for spare parts or service requests on the HR30R v2 and had to fix it myself. I used electronics not made for the light, as I wore out the rotary switch and cord of the predecessor in about 14 months—or a bit over 2,000 hours of job use—past the 1-year warranty period. ** Warning: The stated runtimes are wrong and mathematically impossible (since LEDs are 200 lumens per watt when underdriven <350mA 3.5V/175 LPW when 700mA 3.7V driven, and closer to 140 LPW, at best, when driven above 1 amp 3.7V). The spec sheet is only correct for the low runtime and the lumens and lux, which you can trust. However, for both the HR30R and the HR35R, figure roughly half the runtime of the spec sheet (6.66 hr on high, 13.5 hr on mid). For the HR35R, expect 12 hr on mid spot and flood. Fenix did not do any runtime testing again—unlike myself—and is electricity-illiterate. (The battery pack is 5,000mAh at 7.4V, not 10,000mAh at 7.4V, which is the source of the Chinese math mistake that Fenix has no desire to fix, since the spec sheet incorrect longer runtimes sell more lights.) ** The real runtime math: The battery pack may be called 10,000mAh on the box for better comparison with other lights, but in reality, it’s 5,000mAh, or 4,800 (times 90% driver efficiency) at the 7.2V configuration (which is a superior voltage for driver efficiency). For example, the 350-lumen setting, at 7.2V, uses 2 watts or 350mA for each 5,000mAh cell (in reality, 4,750mAh ÷ 350 = 13.5 hr on the mid setting of 2 watts of 350 lumens output). It will be 6.66 hours on high (4,750 ÷ 720mA draw on each of the two cells at the same time). I wrote many letters about the incorrect runtime on the HR30R v2 spec sheet, but apparently, they didn’t forward my letters or voicemails up the management chain to the top—or else, Fenix decided to continue the error, just to sell more lights. --- Other comparisons to last year’s HR30R v2: ** Last year’s HR30R had a horrible spot CRI and temperature, while the HR35R is beautiful and apparently high CRI (color perception is 95% in the center of the eye’s vision). ** I had to change the batteries every day and constantly switch to the lower amperage settings when using last year’s HR30R v2 for work. I found that I hated doing this so much—even though I carried 2 cells dangerously in my tool belt—that I ended up working for hours on the moon mode rather than stopping what I was toiling at. --- My review’s Star rating considerations: ** It’s a 5-star work light, and I hate to discount it even a single star, especially after doing head-to-head comparisons with other headlamps and flashlights—where it stomped other 5-star lights in brightness per watt and color rendering, just for starters. However, it might, in theory, be demoted 1 star for the false runtime claims—not to mention my experience with the lack of post-1-year service and parts for the HR30R. Moreover, they need to offer new HR35R buyers a discounted option for some kind of extra battery pack, as they now leave users on their own if they have range anxiety and want a backup pack for any reason. As a result, either a 5-star or a 4-star rating is appropriate. I am editing back to 5 stars after doing head-to-head comparisons at work! They deserve 5 stars for the design details and improvements in this year’s model—for example, the safety proximity sensor for the turbo mode, the high CRI, the better beam pattern, which finally allows a 12-hour constant-current runtime at an awesome lux up to 2.5 meters from the inspected surface without dropping below 1,000 lux, while offering ample lumen output. --- Other notes: ** The battery pack from the HR30 works on the HR35R. ** They also give us an extra cord we can cut and make into our own 2S1850. ** This uses a standard 12V AC plug size. ** I am all about 1000lux at 2 meters for 10 hour workdays, for optimal set and forget work headlamp use. The HR30R and HR35R converted me from being a spot-only person (due to runtime and lux considerations of previous models) to using the flood for brief periods—like non-visually-intensive tasks such as folding laundry or double-checking my work with a different, albeit less battery-efficient, type of lighting. ** While the HR35R has a beautiful, strong, useful flood, I do miss the separate spot and flood control for certain applications. This is the only thing I miss at least once a day, for about 15 minutes when I get home and moving around the house. ** If you are not interested in runtime, super visual acuity, and are only a flood person due to the type of work you do, I would recommend the HR30R instead of the HR35R due to the separate flood and spot control. But if you need a mix during the day, stick to the HR35R, since the HR30R v2’s spot has horrible tint and less efficient shaping—resulting in only 6.66 hours of runtime, versus the HR35R’s 12–13.5 hours of better beam discipline, keeping the same intensity at half the milliamps.

This headlamp is heavy with inertia as you turn your head. It took me a while to get used to it. But if you want powerful illumination that lasts as long as you work, or play, all in a rugged package, this is it. I’ve used this as an area work light, hanging it from a fence in the rain for hours, as a headlamp for running my dogs in the dark (when you need to see far enough away to have reaction time and for cars or snowmobiles to see you and your team) and for those 1AM repairs on a ladder. When I have a task where I may need some light, this is the first tool I grab. If weight is an issue, there are lots of other Fenix headlamps and flashlights. I also have the HP25R which is my backup choice. But since things often take longer than I hope, the HP35R buys me time on task without losing light.

This thing is awesome. If you can afford it, buy it. You won't be disappointed. I bought this for night time walks looking for our livestock and I am blown away by how bright it gets but then it also stays that bright with very little fade. The battery takes quite a while to charge, but I have used mine several times now and it is still showing full bars. The knob and button function work excellent. No cycling through a bunch of settings to get where you want. Very easy and intuitive.

Edit: after using this light I can say that I am disappointed with the way they are now advertising the maximum spotlight runtime. This light still “steps down” presumably based on temp after a few minutes of usage. I was incorrect and based my review on trying out the light when I first got it and not from actual usage. I’m disappointed now that I know better. I wish there was a light like this that would run on spot until the battery died and get away from this “turbo” junk that always quits at the most inopportune moment. I should have read the fine print first. I have been reluctant to step up to a larger headlamp that had a separate battery compartment wired in the way this one is set up out of fear of it being too bulky or heavy. This light only weighs a pound and is significantly brighter than any other single 18650 powered headlamp I’ve ever used. I specifically use this light for navigating a hunting boat in the morning before sunrise. Maximum travel time is approximately 20 minutes, and I always got annoyed with a headlamp that advertised a high turbo output that only lasted a minute or two. This light outputs its maximum intensity for the full battery life. This specification is what put me over the top to go ahead and purchase, and I have not been disappointed so far. I haven’t attempted to measure the maximum distance, but using the light at my front yard and home, I could see the color of the leaves in the tree line 200 yards in front of my house.
