The best version Hd2010 today?

Was just playing around with my UF HD2010 and noticed :~ that they got the SOS “backwards”….
its blinking OSO :party: :party:

Ordered an Fandyfire for my friend but no sight of it yet…
Thanks for all of your inputs on the matter.

My Tmart HD2010 started having issues after two batteries worth of use, the driver is the good direct one but it whines like crazy now and flickers. Its a crap shoot. The only Tmart light that has been trouble free for me is the Tangsfire C8 version, I use that one all the time and it has been durable. Its my main bike light.

Man, sorry to hear the Y3 mod didn't work out so well. I just did 3 different nice light mods with OSHPark custom DD boards piggy-back's with my custom e-switch firmware (1 click OFF) and got outstanding results - real happy with them:

  1. Warsun X60 - 6.6A on a Efest 26650 Smile, XM-L2 T6 4D - awesome tint, 1,608 lumens @30 secs
  2. SupFire L5 (from RMM @Mtn), 5.47A on a KK 26700 5000, awesome XM-L2 T4 5B1 80+ CRI on a MaxToch 26 -- 1,363 lumens @30 secs
  3. FandyFire K2, measured only 5.33A on a Efest 26650, but assembled, the lightbox tells a different story, with a XM-L2 U2 1A on a 20mm Noctigon, 1,625 lumens @30 secs, 51 kcd throw (450m). Since I couldn't get the K2's tailcap off, I used a custom made copper ground strap from copper sheet metal that cross's the neg. spring and comes up the inside of the battery tupe and bends over the edge of the tube, where it threads into the head This worked out great and boosts output by a good chunk, about 175 lumens (verified by my lightbox measurements)

I simply use 22 AWG silicone for the grounds - 3 separate places form the contact board to the edge of the suspended driver - provides ample electrical connection and pretty good heat path, as well as a solid foundation. All the custom DD boards (new generations) have some sort of ground ring on the top and that's what I solder those 3 legs to. I try to find pads that have a ground connection (use DMM to check for continuity), rather than using the ground ring of the contact board because that could interfere with the contact board mount. The 22 AWG wires are soldered angled, not straight up/down.

For the LED+ wire, I try to go direct to the springs, drilling a hole thru the contact driver. For the K2, I couldn't do that because there's no driver spring - it requires button top cells, or at least cells that bump out on the + side. So for the K2, I wenwt direct to a fat pad on the contact driver board.

Ahhh - I'd highly recommend the Efest 26650 IMR cells btw. I'm getting as good, or better high amps out of these DD mods than the hot 2500 mAh 18650's (SONY VTC5, Sam 25R, LG HE2, etc.). Besides they have 3500 mAh and not 2500... win-win, great for HD2010's too.

The first Yezl i sold to a colleague of mine( he like it as it was), but i ordered a new one, and will continue the modding, also got hd2010, plus m12 sniper on its way and the new Olight

My goal is to find the most suitable thrower for my rifle, unfortunately 2battery ones are a bit long( and heavy), Yezl was perfect fit though…will check the others now, and will compare

Yes, thanks for the Efest suggestion, i ordered one for evaluation, its price is good too, unfortunately we dont have KK 26700 in EU, but i got also Keeppower 4200ma and Trustfire 5000ma( those aint good definately)

Can i contact you for a future modding assistance?

Sure! Been busy and will be a busy holiday season, but I'm trying to make more time for BLF.

Those days i got the second Yezl, and today a pack of 26650/18650 batteries
Out of the box Yezl( the driver seems better this time) and Efest IMR 26650 64A 3500mAh vs Samsung INR18650-25R vs Keeppower IMR 26650 4200mAh 3.7V (50A)
Y3+ Efest- 2.49a max
Y3 + 25R - 2.55A max(aver)
Y3 + Keeppower - 2.72A max(aver)

The batteries are new, out of the charger, and since i have to charge alot, first results were wierd so i tested with all i had, same results

A bit vierd though…its either those Keeppower batteries are good, or Y3 driver just dont like 25Rs…unfortunately i bought only 1 Efest battery for evaluation

25r realy shines on LD 1 driver

Actually I'm thinking.... The Efest cell is doing the best!

This is a buck driver, so what you are seeing is that the Efest can deliver higher voltage, so draws less amps. I'm not 100% on this, but I've seen this behavior many times before in other lights that I know the better lower resistance cells do measure at lower amps.

That Efest cell is the best cell I know of. If you were to use it with a DD driver, you would see the highest amps out of it. Mine compare almost dead-on, maybe slightly ahead of the Sam 25R, LG HE2, Efest 35A 18650, and SONY VTC5. But of course you got 3500 mAh instead of 2500 mAh with the 18650's, so it maintains higher output for longer.

I`ve tested in on the LD1 driver, Efest here is slightly(0.1amps) better than 25r, but again Keeppower is better 4.8amps vs 4.5 apms, internal resistance of both( measured is nearly the same, arround 45mOms) Efest claim they have 12moms IR but my measurement say: arround 40moms with 10% error
Yet, Efest is nearly 2 euros cheaper, whitch is good, i ordered KK 26650 4200ma, but i dont know when or if they will arrive, shipping that kind of batteries is a pain

Tom, as a pro modder i wanted to ask you, is there a safe way to remove a flashlight label? I tried acetone…gas…kerosene…not working so war :slight_smile:

Label? Not sure exactly what you mean? Like a sticky label?

I think he means the logo on the side, which is usually laser ingraved, right?

Oh, probably the engraving, yes - never tried removing that stuff. Others would know better - I'm no pro - just been around long time Smile. I'm sure you could take off the anodizing using O-L recommended methods, specially with the cheaper anodizing most of the lights have.

Is the Yezl Y3 better than HD2010? I would like to buy a 2010 without needing to mod LED & driver.

Get this Maxtoch, best 70$ you’ll ever spend!
Other lights need mods to get at that level.
Link to mtn

Yeah right, Lucky sun doesnt sound nice to me :slight_smile: Bu the ligt is good realy, i just was that sun stuff removed, but it seems its kinda hard

Mxm…you see, i got either Y3 and M24 ( damn you BLF :bigsmile: )
M24 is 68$, but you pay a visit to the customs office too: final ammount is like 90$,considering VAT, TAX …gas too…waiting in there is booring too btw…
Y3 on the other hand can be bought for 25$, and no customs

They use same emitter btw, i think its T5-6 XML 5000K( measured them) , Maxtoch claim its U2 bin, but there isnt any u2 binned emitter at 5000k( they claim it in the review here)
By default M24 is better than y3, but with LD1 driver( or simmilar) + U2 1A dedomed emitter on Cu board Y3 realy shines, and it would cost like…50$ tops this way
Plus its shorter(1 battery version), and will have better driver and better driver features, plus better dedomed emitter, 5000k isnt for dedoming
M24 has way better finnish ofc

And M24 isnt 26650 based, still waiting for HD2010 and the New thrower Olight, will compare them all when they come

Sry Mitko was reffering to “feilox” question.
I think he’s in the US so he dosn’t have any fees except from shipping. The Maxtoch Mission M12 has a single 26650/26700 Battery. Review by TomE
I only suggestet it as feilox didn’t want to do any modding.

I own two Y3 and got some copper mpcbs and 26650 on the way for myself. I’ll boost the stock driver and might change the emitter, haven’t decided that yet. Fun light to play around with. :smiley:

Yeah, i forgot about that….they have also gas for <2$ per a gallon too! :bigsmile:

Its a good fl though, btw, moth M24 sniper and Y3 have same weight, Y3 is 10 grams heavier: without the EX tube

I finaly obtained relatively good result with LD1 driver and y3, 4.6 amps at the tail

Tom, how to connect the default driver el button with the LD 1? I have troubles with this

Well, i bought thet HD2010 as tryps advised me….
Took it vs 15$ altogether with some led keychain btw
Good enough reflector, relatively okay host, no damage to the main body, seems steady too

And the driver:

Got nearly( 4.31amps) same result with 25r battery

So….the driver is good to go as it is, i never expected that from a 15$ flashlight
It makes it the best 26650 offer so far, for me at least

Wonder though….low long will it last… that driver seems to be very simmilar to the East 92 i bought from FT last year btw

Nice ! You got lucky there, I received my zt-08 and it does have an aluminum reflector. But it’s to small, so it rattles. Will have to put some mm of copper below the led. Yours will get great with Noctigon and possibly AR lens. (kaidomain still has them)

One of the tricks with the T08 is to loosen up the pill to tighten the fit with the LED/MCPCB. Actually I've done that with a few different lights. Hopefully the down pressure from the reflector will keep the pill having a good electrical and thermal connection. I usually add some good thermal and/or electrical conductive grease on the threads. All the T08 pills I've seen don't thread tight anyway - never cared for that aspect of these lights.
