My testing has showed over 90% efficiency for the stock levels, starts to drop off as more current is demanded with a resistor mod though. Check out the numbers here.

Very nice! The stock level is more than enough for my liking. Too bad it cannot drive more than 7V reliably. This is a better option than the expensive Taskled Luxdrive for 6V LED applications.

Well at some point I want to pull the inductor and try to reverse engineer the board. If it is indeed the TPS61088 we should be able to bump the output up to 9V+ for a triple.

That said, even stock it is a fantastic driver for 6V LEDs, especially for the price.

I will probably get either this KF8 host or the 26650 K5 host.

Still comparing….The K5 has better runtime but the strike bezel won’t be good for my jacket pocket. The KF8 SS bezel is also stronger.

Being an XHP50.2, smallish sized and orange peel reflector, the number won’t be spectacular. This is an all around general use FL I guess. But very potential for some eco builds

Agree clemence – just nice to have an idea of the throw. I use my c8 and maxtoch 2X hunting and this would fill a gap for a general torch that if able could be used for some short range work

Would it be 30kcd?

Would be better if KD puts an XHP70 in this KF8. With resistor mod you will have 3000 lumens pocketable light!

Djozz are you able to test with another battery? Like a panasonic ncr, for lumen/kcd/run time?

This torch appears to be much better than most lights – 2k lumens without step down, 40min run times and only a 1×18650. On performance it beats blf models, convoy models, it seems only the higher end options can perform better.

Any reason why? Or just classic blf – high performance low price

Do you guys know about any alternative flashlight in 1×18650 XHP50.2 configuration? This one was sold out pretty quickly and from a different thread (KD insider?) I understood it is unlikely it will be available soon again.

Anything with good heatsinking and the ability to take a 20mm driver could be converted to XHP50.2 using the H1-A boost driver from KD.

Thank you, feel myself rather kind of newbie (my 1st post here) and would preffer already factory made flashlight if such any exists. Am OK with the conversion too – any tips for a host with good heatsink and 20mm driver would be highly appreciated Smile

Hopefully someone else can chime in to confirm, as I dont personally own one, but I was told that the Thorfire C8S takes a 20mm driver.

OK and how about Convoy M2 – anyone know if this is a good candidate for XHP50.2 conversion too?

Thanks for the review. When I first noticed it, the flashlight was already sold out. The specs looked really good for a flashlight for the price..

Thanks Lowtech but Eagle eye x7 comes with 26650 battery, does not? I am seeking for 1×18650 / XHP50.2

It does yes.
Kinda rare with a 18650 light and 20mm driver.

Post if you find any.

I have tried the XHP50.2 with the Eagle Eye X7 reflector and found that the beam, even though there was no obvious donut hole, was fairly uneven and ugly. For a really nice beam with the XHP50.2 still a OP reflector is better IMO.

Yep, the 26650 K5 also comes in 3 tints. Unfortunately all 3 tints of the KF8 are sold out. Was very popular!

From this post :

I received two from this seller on Aliexpress, one late March and one mid April both had a 19.6 mm driver.

I think the C8S with a OP reflector and a XHP50.2 is a nice mod, much better that the X7.

Be careful buying the k8. I ordered one 17/5. They still haven’t shipped it. On 23/5 they told me they are still checking the light before they send it. They would ship before last week was over. They haven’t replied to my messages since then.

I am sorry for the delayed of your package.

I prefer some checking before sending the lights out. And this was consecutive public holiday in this week.

Hope you can understand with us.

And your package had already shipped out.

Thank you
