5.0 out of 5 stars After 30 days of constant use - High Quality build/parts, Light Output AS ADVERTISED, Great Price!
Reviewed in the United States on May 25, 2021
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.

5.0 out of 5 stars Perfect, Practical for Dirty Work/World
Reviewed in the United States on February 13, 2021
I use this light as my backup to the more expensive version of this light. Same design, same function, some extra lumens, some extra money but otherwise, the same. Really, they're damn near the same.

It's simple. It's bright. It's durable. It works. For this price, I don't think you can get a better light that will suit your everyday and even the special days, light. I use it at work and it's backup in caving bag. It's in the backup category only because I don't have a way to recharge it in a cave. USB ports are lacking down there but everywhere else in the world today, a usb port is seldom out of reach. So much better than regular rechargeable batteries. I love the way this recharges and it is my go to light for hiking and work. I have a dirty job as a construction inspector. I need BRIGHT and reliable light to perform my work. Not just to get around, but to look and evaluate welding. This light is great. It's light weight on my hard hat. It's easy to use as well. Just hit the button.

I love how long the battery lasts. I have yet to have it crap out on me before I am ready to stop doing whatever I'm doing. I recharge it after a few uses to make sure it stays going. I often walk the dog in the woods at night. We do a 3 mile loop in the park on a single track trail with lots of obstacles to trip on. It lights it up perfectly. It floods the woods with light. It's more than adequate but not so bright it's annoying. There is such a thing as too bright nowadays. I feel confident when I have this light on. Probably too confident as I seldom think to grab a backup light for our night hikes. That's against me, not against the light. It's just so reliable, I don't have to think about it.

It's feels light weight on the head too. I forget I have it on. The straps are easily adjusted and hold tight without giving a headache. I have had problems with lights that don't hold without squeezing your noggin. Not this guy. I'm really glad when I bought a backup for the more expensive one (I needed a backup because I keep misplacing the other one) I choose this one, and this brand again.

I all around love the metal housing - no plastic - that has seen wet, dirt, sand, and just about everything icky out there. Cave mud to trail mud to jobsite mud - I'm covered.

I give this light my dirty girl stamp of approval. I wish I had numbers on run time but since it does just work, I don't end up thinking about it. It's easy to charge in the car, at home, or with a brick in my bag on the go. For this price, you will not get a more durable, bright enough for anything normal, good to go light. I think I might buy a third honestly just to keep around.

4.0 out of 5 stars Bright with a few slight design flaws…
Reviewed in the United States on February 27, 2024
I bought this headlamp for use in wildland fire and it is the best lamp I have owned so far. It is bright, fast charging, and you can focus the lens.
There are a few small issues I have with it however, the first being the clamp that holds the lamp to the headband is brittle and breaks easily. I rarely remove the lamp from the headband so having the clamps is useless to me and having to zip tie the lamp to the band makes it very difficult to adjust the angle.
The second issue is the bulb doesn’t have a lens to keep dirt, oil, moisture, etc off of the bulb and reflector. When debris get into the space between the bulb and reflector it is difficult to remove without scratching either surface and the debris and/or moisture create dim spots in the light pattern.
Aside from those issues the headlamp works as advertised and is reliable. Having a second battery purchase option would also be nice for those of us who use it all night long away from the engines with no way to recharge it.
