Review: UltraFire HD2010

Good way to start your morning. Thank you for the review.

Could you please take a tailcap reading again after a couple weeks of general use? I am curious if after a while your tailcap reading will inexplicably drop below 4A no matter what you try, like it did to some of us here...

Love this light, does throw really well that got me take 2

Hey taz… I just thought of it this morning, I wonder if your springs have annealed and softened from the current flow? So perhaps now they have compressed to the 650 battery length and you are loosing contact force between the springs and battery??

I had this happen to my TR-J12 only it was very obvious… the smell and cell rattle gave it away immediately after a ~20 minute (HOT) run.

The TR-J12 draws upwards of 5-7A at its peak, when Vin drops. Thats not too far off from the peak ~5.5A I was getting from my HD2010 when I had the stock driver in there, and the springs were pressed completely flat.

Whereas when I took a reading the first time, I was afraid to press down because reading started at 4,2A and when it went to 5,2A I stopped,thinking I would damage the emitter somehow, now I start at 2,6A and pressing on the battery until it compresses the spring to the max possible, I get about 3,9A... could this be caused by the spring? Can somehow a driver stop performing to the max? If it was a driver that had multi AMCs I would think that maybe one or more are not functioning, but this driver doesn't have many chips on it... and I really wish there was a compatible driver that would give 5A max to swap this one out... it's a really great light, and knowing that normally it easily goes to 5A, doing 3,5A now is a bit annoying... The thing also is that in the other HD2010 related threads, there are other owners I think who cannot do over 3A...

Thx for the awesome view Foy!

Nice review foy, I’m thinking of getting this light. looks like a good one.
But not from Tmart.

Thanks for the info, Foy. Much appreciated :wink:
As for tint… cameras can actually adjust some things and tint could look different on pic. Does your pics are close to real life/your eye-meter? :slight_smile:
To make a good comparison of hotspots and such, I think a pic with lower exposure shows those differences better :slight_smile:
Hm, strange, but looking at those pic you’ve made, HD2010 has brighter spill to me outside, but inside, M8 has better spill :expressionless:
Good to know that you can run it with 18650 without loosing much current/brightness :stuck_out_tongue:

Very interesting. Have you bought yours @DD? They sells it for 34 without any coupons :stuck_out_tongue: Add a 10%coupon, add some points and you will get best bung for the buck. Or not? Can you see PWM on yours? Thanks in advance :slight_smile:

I haven't seen the Tangsfire so, not sure what the differences are but because you had the same thing happen during testing that I did, would seen the driver might be the same. You are right about the switch, although I'm probably less bothered by it than you. I didn't really notice until you asked but the switch on the JM05 is very crisp and feels positive. The HD2010 is mushy by comparison but it might be because the JM05 uses a 14mm boot and the HD2010 is 16mm. Honestly, though, I don't think it's the boot.

I see what you're talking about but mine hasn't done it. (yet)

Taz -

I will do that but I must remind that I've had this light since 6-8-12. I hesitate to say this but if anything, my HD2010 actually measures a few points higher now than it did 3 weeks ago. I think it's because I removed the collar that held the spring cap down. The spring now presses slightly harder on the battery.

When I first got the light, my Extech measured a high of 5.0 amps that settled to 4.40-4.50. Today on my new Sinometer with a King Kong fresh off the charger, it begins at 5.40 and settles to 4.80-5.0 amps. I have experienced no current drop at all. If anything, it's higher now.

I had my camera on manual but the white balance was on auto. Usually, the best anybody can do is put up something to compare to and not something someone could expect to see themselves.

Agreed :bigsmile:

Link to that TangsFire :wink:

I wish my HD2010 looked as good as that DD pic. Also, I paid more . . .

Thanks so much for another great review Foy! Frontpage’d and Sticky’d.

I want one of these but never pull the trigger for some reason…

thanks for the review foy…

You should! They are excellent value-for-money. I have one, and already considering buying a second! Nevermind that my wife also likes it and wants one for my father-in-law...

Agreed! A phenomenal light!

I got issues with the ano finish and I remember hearing of tailswitch problems awhile back…i’ve kind of lost love for lights with problems from the factory…

I hope mine is in better shape. I ordered one about a week ago.

I have had a half dozen of these come in for driver swaps and all of them had marks on the ano and also on the reflector. I finally got a perfect one it’s the first black one I have seen and my first order from Lightmalls for $38.90. I don’t know if the defects are limited to the gray ones or if Lightmalls has a different supplier. I can say I really like this light and finally getting one with no defects is nice.

The East-92 driver that is also found in other flashlights, is it available anywhere online to buy???
