Skilhunt H04 RC Review (Nichia 519a, Headlamp, 96CRI)

The Skilhunt H04 RC has been out for a few years, but what’s new here is the LED that’s fairly new being offered, and that’s the Nichia 519a. You know I’m a fan of that LED and I can tell you it makes a great choice in a headlamp for close-up work with it’s neutral tint and high CRI. Thanks to Skilhunt for sending this to me to look at.

Packaging & Accessories

The light came in a retail hanging box with lots of good information on the outside. Accessories included were the light, pocket clip, 3500mAh 18650 buttons top battery, proprietary magnetic charging cable, Skilhunt branded 3 piece head strap, lanyard, extra o’rings , mesh bag, and the manual. 



The UI on this version of the Skilhunt H04 RC has been updated from previous versions. It’s similar to what I saw on the M150 V3. Turning the light on with a single press will bring you into the main mode group in the last mode you used. Long pressing from off brings you into the ultra-low mode group. Within ultra-low, you have 2 brightness options, that you can toggle between by long pressing. This same sub-mode group works with Turbo too, so turbo high, and turbo low if you will. So once you have the low end and the top end set you effectively have a 5-mode light that works like most others. Long press from Off to ultra-low, single press for your main mode groups where you long press to go up in modes in a 3 mode group, and then double press for turbo. Strobe is triple press from on, and it also has 3 strobe modes, tactical, SOS, and Beacon. Lastly, there is electronic lockout which is 4 clicks from off. The mechanical lockout also works well here at the tail cap.



The light is made from aluminum and hard anodized black in a semi-gloss shine. The tail is magnetic, strong enough to hold the light in the horizontal position on a painted/powder-coated surface with the strap attached, but barely. The tail itself is mostly smooth. The light comes into 2 pieces, tail and body/head. The body has shallow milling for texture. 

The head itself is pretty typical of other right-angle flashlights. The lens is round however there is a flush metal bezel that’s square. The lens has texture over top to somewhat diffuse the light. On top you have the recharging contact for the proprietary charging system. On the left you have the button which sits slightly raised. It’s a silicone button surface, semi-transparent and is used as a power level indicator and recharging status indicator.



You have 3 main retention options with the H04 RC, a lanyard, pocket clip and the 3 piece headband. 

The pocket clip itself is press fit and is designed to fit, just under the head. It is pretty tight but can rotate. It’s a good clip as far as tension goes but not what I would consider deep carry as a little over 1.5cm sticks up beyond the clip.

The headband comes unassembled on the H04 RC and no directions were included on how exactly to assemble it. I did find a video on Skilhunt’s YouTube page showing how to do this and it was very helpful. The headband itself is made of good quality elastic, on the inside, it has a silicone band to help it stay put, on the outside it has some reflective pieces The plastic mount itself has no padding like you see on some other brands but I didn’t find this uncomfortable during use working on my car. What I really liked was that the mount is designed to work with the pocket clip still attached to the light. This is the way it should be done. There is also a lanyard that comes with the light, and it threads at the back of the light.


Size & Weight

I measured the length at 101.5mm, the diameter of the body at 21.2mm, largest diameter of the head at 24mm. The weight of the headlamp with clip, and without the head strap came in at 3.69oz, and with the strap, it grows to 5.45oz. The light is IPX 8 water-rated and impact resistant to 1 meter. 


LED & Beam Shots

This Skilhunt H04 RC is running a Nichia 519a which is best known for it’s pleasing tint and high CRI. On my Opple meter, I measured the tint at 4211k, and 97.5Ra (CRI) with no DUV shift. This is pretty much perfect for my preferences. I would also call it a constant current driver, without PWM on the multiple modes tested. 

The headlamp here is using a TIR optic with texture on the outside and the resulting beam pattern is a large even beam without a pronounced hotspot. The spill is minimal. In the use of the headlamp, I found the beam to be maybe slightly too narrow for the automotive work I was doing, and I found myself manually adjusting the angle of the light a few times more than I would have expected. 



I will let the graphs do the speaking here, but in general, the outputs are less than Skilhunt claims and I think this is due to them not updating their runtime charts for this new Nichia 519a LED that’s inside. The result is turbo can last to nearly 3 minutes, but you’re starting at about 620 lumens.  Peak heat was about 43C so very reasonable temps. Turbo 1 and Turbo 2 runtimes were in the 3:30:00 runtime range, High out to 5:22:00, and Medium one all the way out to 14:30:00. 



The light has built in recharging via a proprietary magnetic charging cable the light comes with. The contact on the light itself has a weak magnet on it, so I don’t think there will be as many problems on this design as other similar ones on the market. While the light does have the proprietary charging cable it uses standard button top protected 18650 batteries which is great for longevity and future replacements or spares. My tested capacity of the included cell was 3455mAh of a rated 3500mAh. 

I charged the light from LVP at 3.074V to Full at 4.185V in just shy of 5 hours. This is pretty slow for a 3500mAh 18650 battery. The peak charging speed was 0.95A but this was a peak, and most of the charging speed was well under that as you can see by the graph. The button on the light does give a power indicator when in use in 4 different states with 2 different colors. 



This is a great little headlamp when you are prioritizing light quality over quantity. Skilhunt really should publish official numbers when they put different LED’s in their lights, because they claim 1000 lumens, but this is clearly for a different LED than the example I have in this review that I measured at approximately 620 lumens. It also creates the mode spacing that isn’t ideal. 

That said I really enjoyed using this headlamp, and I suspect it will become my new default when i’m doing closer-up work or something where CRI is important. This isn’t the headlamp ill pick to snowblow in because I likely want more output for longer periods of time. It’s a headlamp I can definitely recommend if you don’t have one already.

Wowtac H01 Review (Headlamp, $16, 16340, USB Rechargeable)

Wowtac has a new headlamp on the market with the H01 and it’s been getting some positive buzz in the flashlight community for it’s low price and high value. It’s running a Cree XP-G2 LED, a 16340 battery, and has onboard recharging. Thanks to Wowtac for sending it to me to take a look at. Wowtac has provided a discount using my code below for the month of July, so if you like this one be sure to check that out and save a few dollars.

Packaging & Accessories

Wowtac’s package is a small cardboard box with everything packed in tight. Good luck getting it to fit like it arrived ever again. The outside has just the brand, model number and emitter. In this case it’s a cool white. Included in the package is the light itself, a Wowtac wrapped standard 16340 battery, a basic Wowtac head strap, microUSB cable for recharging, 2 extra orings and a spare usb cover, and the manual.



The light is made from aluminum and machining is pretty good for the price, my only small complaint is the milled heat syncs in the rear of the head still have slightly sharp edges. The tail allows for it to tail stand but there is no magnet. There is nuzzling in the body section that’s pretty standard. Threads between the head and body tube are anodized, short and square cut. There is only a spring in the tail of the light with the head having a small brass post. 

The head has the microUSB charging port directly to the left of the emitter when looking at it head on. The port cover sits flat but the little pull tab does stick out more then I would like. On top the semi transparent silicon covers the button and sits slightly domed and smooth. There are LED underneath that are used to indicate the battery charge level and during recharging. The lens is a deeply recessed TIR style optic held on with a exterior retaining ring. 


Size & Weight

I measured the length at 67mm, diameter of the body at 21mm, maximum diameter of the head at 22mm. Weight with the battery was a light 47.7g. The light is IPX8 rated.


Comparisons to other 16340 sized headlamps.



No clip is included with the H01 which is a little disappointing but I can see why they did this given the price point and it would have been a tail down carry most likely given how the body profile is cut. The headstrap itself has a silicone mount with 2 loops and the light will mount in either direction. The straps are black with Wowtac woven into them. There is no silicone grip strips on the inside of the around the head design. I found the headband comfortable with how small and light this light is.


LED & Beamshot

The H01 is running a Cree XHP G2 LED in cool white. No specific tint is given. This does the job pretty well without any undesired tint issues like the XHP-G3 LED has so I appreciate Wowtac making this selection. My beam pattern here has a centered hot center from the TIR with a good amount of spill. There is a big of a square pattern to the spill of the beam, it’s especially noticeable at shorter ranges. There is some PWM in the middle modes, but it’s not anything I notice or my eye does. 



  • Turbo – 614 Lumens
  • High – 198 Lumens
  • Medium – 62 Lumens
  • Low – 16 Lumens
  • Firefly – 0.5 Lumen
  • SOS – 176 Lumens

Runtime & Heat

For my runtimes I ran the light with the included 650mAh 16340 battery. Turbo in my tests lasted for 70 seconds, a little shorter then what Wowtac quotes, from there it continues running in the 35% relative output while slowly falling over the next 80 minutes following the decline of the batteries voltage. It’s a regulated driver but the regulation isn’t’ the best. The FL1 standard comes in at 1 hour and 27 minutes of total runtime but the light continues making light out to 2 hours and 13 minutes. The last 30 minutes of runtime the light does flash on and off every  few minutes, it’s impossible to still notice if you’re using the light at the time. When the light completely shut off I measured the voltage at 2.895V. Maximum heat I saw was 42C.

I did try to run this light with a CR123A battery as it physically fit’s in the light but the driver isn’t designed for the lower voltage range and you end up getting the low power warning which is the light flashing on and off in kind of a beacon mode.



UI here is pretty standard from WowTac and Thrunite. Long press from off to get to the firefly mode. From off a quick press gets you low, and holding the button down then starts the light progressing up it’s 3 available modes. The light does have memory mode in the normal L-M-H modes. Double press takes you to Turbo, and Triple press gets you to the only blinking mode SOS. 



Recharging the light is accomplished via the onboard MicroUSB port on the side of the light. The LED’s under the switch turn red when charging and blue when charged. While it would have been great to see USB-C here, but this light was built with a low target price so MicroUSB it is. I measured the total recharging time to take 1hr and 33 minutes, maximum charge rate was 0.52A, so just below 1C. I measured the charged battery at 4.15V.


  • High value, small and lightweight
  • Standard 16340 Battery
  • Neutral white may be available in the future.



  • Unlike many other headlamps it’s not designed for pocket EDC use, there isn’t a pocket clip or tail magnet. This does help save cost.
  • Driver isn’t designed to use a CR123A battery and gives a low voltage warning if one is used. 
  • A bit of a square pattern to the spill of the beam



If you have watched my reviews before, you know I am a headlight proponent. I use a headlamp often around my house and car when cleaning, doing home repair projects, and just other stuff, because it allows me to have both hands free. The Wowtac H01 offers a good, low cost, basic headlamp that gets the job done. It has enough runtime on the lower modes for moderate sized tasks and is a great value for getting a complete package here with the battery included, and fast shipping from the US. If you want longer runtimes of light with a larger battery it’s going to be better suited.


My con’s list isn’t that big of a deal given the cost here and the focused headlamp only use. It’s been a while since I have seen a light with this square of beam pattern, it’s not my favorite for sure but something a non flashaholic won’t notice probably. I can recommend the H01 if you’re looking for a small low cost, rechargeable headlamp with decent runtimes, it’s certainly a much better option then genetic headlamp options from brands you have never heard from that’s available on Amazon.
