SLONIK Rechargeable Headlamp for Adults 1000 Lumens Super Bright 600 ft Beam

First Misleading Reviews - unfortunately well intentioned reviewers misinterpret technical spec documents and make mistakes that tear apart good products like this one. This is in response to Kimberly's Review of the specs included with the SLONIK S25 model 1,000 Lumen, dual LED Headlamp, and the product itself & the packaging, accessories , etc.. First I can understand and even empathize with her frustration as to why more electronics aren't made in USA and the relatively lower cost of products made in Asia, some of those products/companies are not reliable & I too have found incorrect or exaggerated specs. BUT in this case - I found SLONIK to be Extremely reliable, customer service oriented, products r very well made, excellent craftsmanship, name brand parts & reliable operation - their instructions are EXCELLENT, clear & concise including warranty information, specs & contact info. Top 10% IMHO as compared to similar electronics I purchased on Amazon in past 10 years. That said - the "False Advertising Claim" you made re: the pair of CREE X-Lamp model XP-G2 LEDs (Proudly stated, BTW, that the LEDs are Made in America!! - SLONIK's primary selling point!).. The Flux output you refer too on Cree's website (pages 6-14) is clearly stated as the "Minimum Luminous Flux @ 85 C & (more importantly!!) @ 350 mA". - If you go to page 17, you'll find a Table - "Relative Flux vs Current" (@ 85 C) for both the Standard and High Efficacy versions of this same LED - the Standard version can handle up to 1500 mAh batteries, the Hi-Efficacy up to 2000 mAh. At 350 mAh - we see it intersects @ 100% - just like you said - if battery was a 3.7V @ 350mAh then Flux (lumens) would be 100% x 164 lm = 164 lumens per LED x 2= 328 lm output from both LEDs. BUT we have a 2200mAh battery - look at the graph - @ 1000mAh it is 250% x164 = 410 each LED (820 lm total) @ 1500 mAh (max for standard Cree XPG-2) = 340% x 164 = 557 lm x 2 LEDs = 1114 lm Total - MORE than Spec claims and well within 2200mah/3.7V battery rating - spec claims that at this level (assuming it is the 100% mode) - you'll get 4 hours before recharge (battery dissipates 8.14 watts/hour, or max of 2.2 hours running full load, @ 1500mah/3.7V load - battery will dissipate 5.55 Watts/hr. My quick math in my head says we should get around 3.5 hours of battery at 100% brightness setting, spec says "4 hours" at 100% running at 10 watts (each LED is rated at max 5V/1A or 5 Watts x 2 = 10 Watts). Anyway - according to Slonik's spec and Cree's Data Sheet for the LED & battery capacity chart (assuming all is perfect - NEVER IS) the Lumens STATED in SLONIK's Spec = 1000 lm for 2 x CREE XPG-2 Standard Version is CORRECT as math and Specs say output @ 1500mah = 1114 lm - Close enough - Color Temp - Depends which model CREE they used - I would guess in Daylight/Cool White range where LED has higher Flux in that 4200-8000 Kelvin range rather than warm white below 4000 Kelvin range. In closing - after about 6 weeks using this light almost everyday with my head and light stuck in 9.5" ceiling holes cut for 4 new Dolby Atmos speakers and new 6" smart Recessed lights (x 8). The storage case, instructions and battery are IMO high end for any price-range, charge cable and integrated mini-USB port - is flimsy - not because SLONIK is bad - that mini USB is awful in general it is unreliable and should be discontinued on any equipment (cell phones included) - it's garbage and a bad idea - if u r careful with it it's fine - get a higher quality cable - I have a spare external 18650 floor charger - I use it for my LED flashlights - BTW flat top battery that SLONIK uses has no connection troubles in my external charge (no electrical contact issues because of small positive nipple on the battery - nipple is fine just like it is). I typically set headlamp on lowest or 2nd lowest setting for my purposes - electronics repair, construction projects, outdoor dark night activities - sneaking around at night & BBQ-ing in the dark. Have not found a practical use for "Full Power" Yet - but man is it bright - and the combo "Spot" & "Flood" HQ lenses are excellent. Charges fully in less than 90 minutes - my only minor complaint is it does get warm if u wear it directly on exposed skin - like my skull/forehead - need to turn it off between "jobs".Band is very soft & comfortable, easy to adjust. In summary, the negative review re: Lumen Output was a simple MISUNDERSTANDING of how CREE's LED Flux output is calculated - & I think some folks paid lots of $$$$ for other "BRANDS" that are same as this & R looking for a "Flaw" in this product that just isn't there.

I have had this flashlight for a while now and it is really a well-made product. Heavy duty I’ve worn in the rain without issue and the battery it’s good. What I like most about this flashlight is once you select the brightness by holding the button in until the desire brightness. It will click on and off with one press the button and remember the light setting. That’s a pet peeve of mine on other flashlights. It can get a little heavy if you wear it on your head for extended period of time, but is by a large comfortable. I use it when I need to be hands-free and have a very bright light. Great for walking the dog or working on small parts where you need extra light.

Absolutely fantastic head torch. Reliable, bright, Battery lasts very well. Its the only head torch that clips to a hard hat well and is bright. It's so good I bought 3 now, 2 for me one for my brother.

I've purchased two Slonik headlamps and they've been awesome. So much brighter than previous headlamps! Battery life has repeatedly been good and I like the rechargeable battery. However, after 3 years the failure mode has been that the plastic holding the light to the headband has broken, so the light won't stay on the headband anymore. On my 1 year older model (2021) that plastic still works and the headband has just become stretched out and white. Overall worked really well for several years, though!

This thing is built like a tank. Its a metal watertight tube with an 18650 inside it and dual heavy hitter LEDS on the side. I have used this light now as a daily driver for over 3 years and while the wear shows on the outside, it still performs as good as the day I bought it. I have dropped this light from 8 feet+ over concrete on numerous occasions with the only repercussion being small dents on the body. The battery life from the get go was excellent lasting me 2 to 3 weeks of use. After about a year and a half I started to really notice it dwindle though. Thankfully you can replace it with a better upgraded battery! (Molicell makes top of the line high cap 18650s) The headband rubber attachment point was a concern for me as a failure point. 3 years in and I have had zero issues with it. There are signs of cracking in some of the joints of the rubber though. The headband is slightly stretched out now, but this is mostly due to having it on a hardhat for over 6 months straight. The wide adjustability range allowed me to tighten it up more so it functions fine still. Overall I give this a 9/10, my only issues being that changing batteries does something strange to the switch. It sometimes won't turn on after swapping unless you take out and replace the battery a couple times. A diffuser attachment would also be very nice for enclosed space work, but this is easily mod-able at home.

I've had this for 5 years now. It has been through a lot and it still works great. I use it constantly and it has a rough life. The best thing about it is that it uses a standard 18650 lithium battery, so even if it dies you can just swap to a spare without waiting to charge it. A lot of other headlamps use special batteries which are expensive, but the 18650 is ubiquitous. After a few years, the plastic mount failed but I printed a new one. I've bought more of these over the years - cheap, simple, reliable. Couldn't ask for more.

The torch isn't as tough as it lets on. I bought this to be used on a 24hr obstacle course race for the night part. I had tested it out and about while training late at night and walking the dogs and it was fine. However, the water rating means absolutely nothing as I jumped into some water with it on and it stopped working. It is completely useless, I wouldn't mind if I hit it and banged it about prior to this, but that wasn't the case. This happened within 1 mile of a 5mile loop and had to run the remainder of that lap in the dark because this wouldn't work. Do not buy if you want it to get wet in any capacity, HUGE waste of money!

I went for this one because of the huge battery and decent price. I also like the metal housing and nifty storage case. The rubber lamp holder works without issue. I rely on my headlamp as a mechanic in a commercial environment, and this light gets the job done as long as you charge it daily. The brightness is very good, with I believe 8 intensity levels. I use level 4, hoping for a good balance of runtime and brightness. I used this on a 3 night camping trip in backcountry, and I found that it was perfectly adequate for the job, still showing green or near full after the trip. This is the second one of these I've bought in the last 4 years. Overall this is a great lamp with great value.

Nice and bright, fits nicely on my hard hat, easy to charge.

Ran this light during night shift on a mine site. Never ran out of power, super bright, super good. Expensive but worth it.

Duración de batería, iluminación para rutas de MTB nocturnas es de lo mejor. Solo su soporte no funciona para colocarla en el casco ya que es de hule. Pero se puede adaptar y queda muy bien
