SKILHUNT H03 H03R led headlamp release, 1200 LED lemens

I see :frowning: I hope heating with an hair dryer will be enough :s

Yeah I didnā€™t mean that, Iā€™m just saying that with the H02 one has to be more careful than with most other flashlights when screwing the cap, especially with long batteries, because the thread are just 2-3 and so the spring is already loaded when the cap threads in. The H03 looks just the same, according to the pictures above.

Got mine a couple of days ago; extremely well made and I love the beam pattern. I will use it for hiking in desert. I am looking forward to comparing it to my armytek wizard.

Man! Would I like to have a word with the inventor of threadlock. I finally got it open but it was not easy. Now it has an xpl and a current bump. Gives good throw. Nice light.

Awesome! Can you tell us more about the threadlock? What have you used to get it open? Have you tried heating the body?

And what about the current modding, sense resistor?

Brute force approach maybe?

up :slight_smile: there should be several people here owing the h02/h15 as well

I guess so, but I mean if vise+pliers are needed or if heating and unscrewing with a cloth and bare hands is enough

Tire inner tube is always a good approach, but donā€™t hold your pliers too tightly or thereā€™s a risk to cut through it and scratch the anodization.
Use soft wood to hold the light in your vise.
Here is my method :

Nice tip, +1!

The tread lock is red and nasty. It took a lot to clean the threads after. I tried mek and isopropyl alcohol, but in the end I had to patiently scrape away at it trying to avoid scratching the threads.

I opened it by holding the head in my hobby vice lined with cardboard. I put a heat gun on the joint for a minute or two watching closely to avoid fading the finish. After heated I took an old leather belt, wrapped it around the tube like a strap wrench. Then I took some channel locks and gripped the belt from the side as closely to the tube as I could. I then used the top side of the channel locks as a lever pushing down against the belt as I pushed down on the channel locks. To do this I had to pry opposite of the normal prying direction of the wrench. Finally some force and it finally broke loose.

There were two R082 resistors in paralell. I added an R100 over the top. This increased the measured current from 2.4amps to 3.2amps. However, I never advise doing this as there could be negative effects or could ruin the driver.

The parts have the same threads, however the thread lengths are different. So the cap from the 02 does not cover all the threads from the 03 body

thanks for sharing :wink:

It looks like a little pain in the @$$ but at least we know itā€™s possible to mod it, thanks! :wink:

The amount of thread lock is ... incredible! LoL.

Awesome!! no problem for the H03 cap being longer, thatā€™s a good thing actually! :wink:

As you can see the H02 threads are a lot shorter than on most other lightsā€¦ in the pictures you see H02 head and cap + Astrolux S1 short tube. I doubt the H03 tailcap would be long enough to cover the oring on the S1 tube but no problem for that, I have a spare tube that Iā€™ve planned to mod for that purpose.

Just noticed the great review from freeme here :wink: Freeme Review: Skilhunt H03 & H03F CREE XM-L2 U4 1000lm Headlamp - incomplete (I think itā€™s the first and only for the moment, as long as I know)

I believe the cap from the 03 will come very close to that oring. I can check later today. I have a short tube with h02 head as well. Right now Iā€™m using that cap from a 503b and it covers up the oring. But no magnet.

wait, you mean UF 503b threads match the ones of Skilhunt and Astrolux?? That would be also very interesting!

By the way, what short tube are you using? The same Astrolux I am using?

Yes, the 503 b fits and covers the oring. I donā€™t care for the look though. I checked the 03 cap on the astrolux short tube and it goes up to about the center of the oring where you have it place. However, the oring can be moved to the slot right after the threads and the 03 cap completely covers the oring and it fits and looks nice.

Thatā€™s some great info, thanks :wink:

No problem. I canā€™t give much more information though. I showed it to a friend andā€¦ Well, I have no more light. :stuck_out_tongue: I do have another one. I will be trying to open that up soon. Hopefully I can repeat the results without collateral damage. :wink:
