I’ve only had it a little over a day, so haven’t had a chance to run it long yet. Been using the 14500 that’s supplied in the kit from Sofirn.
I got mine off of their Shopee store, which is a Southeast Asian e-commerce platform. If it’s not available yet in your local Amazon I guess you have to get one off their website. Shipping’s not too bad from China, I got it in under 10 days.
Have you tried if there is pwm at every level?
You can put the light direct on a portable fan for detect if pwm is slow,fast or absent.
Would be very nice if Sofirn add also a ramping mode that will start always from level Eco (no memory mode)
Except the size is there a major advantage over the SP40 ?
(It’s looks like the ui is better but no usb ?)
Can you imagine how many would try and charge an Alkaline AA
Thanks, I missed this info. 
Sorry I didn’t see your message earlier. I do have a room fan, I’ll give it a try tonight. PWM doesn’t affect me but I know it’s annoying for some folks.
Also, is there a way to get BLF to notify you when someone responds to your comments? Might be just me but I couldn’t find any options in the settings. Feels like the type of thing that should be a basic toggle in this day and age.
Don’t know,usually I get auto notification on my mail after wrote on thread,but sometime it miss.
Or maybe you deleted for error the notify about this thread.
About this light,as said lack Ramping mode and sublumen,helpful to read a book,
hope they can upgrade.
Or even better would be an headlamp with emitter and lens on the center + 2 red channel.
Instead angle type,since there is already SP40
I’ve ordered recently from Sofirn, claiming they are putting 5000k in.
While it’s nice and warmer than some other flashlights I own, I would love to see this with 4000k LH351D.
I’m ready to buy another one, once they release 4kk 
Here’s my in depth review with the 6000K variant
Just received mine today. AE shipping has improved…. Anyways really digging this little light and even though I’m normally not a fan of mode memory it seems to work here. Direct access to moon mode and three simple modes
To cycle through by holding. The 5000k LH351D isn’t as dog-farty as some, it’s even better than the recent one from Simon I installed in a fenix hm50r. But after using my 3500k LH351D TH20 for a few hours doing car work I’m reminded how much I prefer a warmer tint closer to or even below the BBL. might have to swap this with a 3500 or 4000k LH351D… or even one of these new again 219B emitters that seem to have come back around. It’ll loose a lot of turbo either way, I suppose…
Do you detect PWM at every levels if you put the light direct on fan blade?
Interestingly, 5000K LH351D in HD05 is noticeably different to SC21 5000K LH351D
Just a little update on my experiences. Been using it around the house for a while but tonight I took it out for a rainy walk down to the lake. While I do really like this little light, I must reemphasize my disappointment in the emitter. Even after driving 3 hours with “6500k” LED headlights this thing looks too far on the cool white/blue spectrum. Certainly not 6500k but far too cool for my taste. Is it 90CRI? Can’t tell with my eyes, everything just washes together though to be fair rain will do that. Ordered the 2700k for a radical alternative but I might have to get myself a 219B SW45 in this one. Just to keep the warm vs neutral theme while still improving the quality of light.
Not that a 14500 has a ton of capacity but does anybody know if you can set this keep the button light on or even breathing when the light is off? Would be a nice combination with the lock out tailcap.
The 6500 LED is not 90CRI, only the 5700K and below are high CRI.
The 6000K version was only sold for a short time, they have since updated it to 5000K
Mine is supposed to be 6500k… Don’t believe it is.
Is there any plan for a group buy?
It’s already affordable but a group buy will keep us have spare money for another flashlights 
Great Reviews and information. Sofirn is now offering these in 2 versions: 4,000 and 5,000 K. I read in an German forum that the beam profile is very floody — to an extend that the reviewer remarked he had light spots on the nose. But I don’t know which version this refers to and assume the different tints have a different beam profiles? Thanks for hints on this.
Background of the question: I absolutely hate an overly wide beam profile in headlamps (with light spots on the nose). I seem to be one of the few people who prefer less floody headlamps. My good old Zebras offer a great combination of 80 degree spill and 12 degree spot… perfect for me.
He must have a really long nose lol. I found it to be perfectly fine.
Both 4000 & 5000K have exactly the same beam profile. Get the Sofirn SP40 XPL version for a longer range maybe, or even the new HS40
> must have a really long nose
LOL. Yeah I pictured Pinocchio too, when I read that the first times in reviews. However, I have a normal nose size and suffered from those spots too with a couple of headlamps in the last year. Trustfire MC12 and Fenix HM51R are two examples (both with TIR lenses I think). Trustfire advertises a 170 degree beam as a feature on their page for the MC12.
IMHO those “170 degrees” are not such a great idea for headlamps since that is much wider than our real field of vision of roughly 120 degrees. Seems a waste of energy and runtime to me. But I don’t do close up work / mechanical repairs or use my headlamps for reading. I need them for running and hiking at night only. For running purposes 18650 lamps are too heavy / “bouncy” for me (is that an English word?) thus my interest in the HS05.
If I don’t find good alternative I will keep using my good old ZL H52w… but for some irrational reason I could really do with a new lamp!
