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.

Rugged, bright
I had two Black Diamond headlamps break on the same day recently. I wanted something rugged; that sure describes this thing. It’s actually very light aside from the large, rechargeable battery. It’s bright and simple to use. If you like confusing menus and tiny buttons, this isn’t the light for you. I haven’t tested it in the rain yet, but I really doubt it will self-destruct upon contact with a water molecule the way Black Diamond ones do. I’d never heard of the brand, but don’t let that stop you. Newer brands of outdoor gear are often better, as the companies haven’t yet tried to squeeze out every penny by making “built to fall apart” garbage like Black Diamond. If you launched this thing at the Black Diamond factory with a slingshot, it would destroy the building, and everything inside. I may try that.

Good Lights
These are quality lights, I like them so much I bought three and gave one as a gift and they seem to be holding up well so far. These lights are plenty bright in the medium light setting for working on close up projects like ATVs, and other vehicle projects. These last longer than the AAA lights which is great when you are on a long project. The full brightness setting on these will light up a big area. These lights are priced right for their build quality, they are waterproof and can be adjusted to give you maximum coverage for your project and they are comfortable to wear. Hope this helps.

Muy buen material, iluminación muy buena y la duración de la batería es buena!!

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
