Review: XinTD C8 (SC-82)

XinTD C8

Reviewer's Overall Rating: ★★★★★



 

Summary:

Battery:

1 x 18650 Protected & NON-protected

Switch:

Reverse Clicky

Modes:

High - Med - Low

LED Type:

Cree XM-L T6 NW

Lens:

Glass

Tailstands:

Yes

Price Payed:

$31.94

From:

Intl-Outdoor

Date Ordered:

25/2/12 (Received – 13/3/12)

 

Pros:

  • Price, imo this is the new best VFM 18650 available

  • No Flashy modes

  • Well spaced High and medium, sensible 2.8A drive on high

  • Good tint

  • High frequency PWM

  • Tailstands

    Low voltage cutout at ~3v

 

Cons:

  • Finish a little rough

  • Low could be lower

 

This light will obviously be compared to all the other C8 lights but in my collection it will be mainly compared to what i considered the next step up, the Ultrafire 980L as reviewed by the master of reviewers on here, Foy (http://budgetlightforum.com/node/2537).

 

 

Features / Value: ★★★★★

 

Compared to a average C8 so well liked by budget flashaholics this refines the genre by doing away with bad PWM and flashy modes but adding a tint to your liking.

This shows the PWM difference:

This compares the tint:

Tried to do the mouse over but failed lol, this is colour comparision with ceiling bounce (not sure if this is useful but i was interested how it would turn out), 980 first:

This is control, lit by several 60w household lamps

Design / Build Quality: ★★★★

Emitter is well centered, and an almost flawless reflector:

The driver and spring which seems to be upside down but im sure its meant to be this way so hey (ignore the random bit holding it up):

 

Build quality is OK, this is the biggest nod to the budget nature of this light, a few marks on the body, infact enough that I get the impression most will be suffering some flaws but you may get lucky.

 

Threads feel good and come lubed, everything was tight and rattle free on delivery.

The tailcap has a small lanyard hole (no good for Paracord, sort-of cocktail stick sized) in one location only so use may interfere with tailstanding.

 

Battery Life & Heat managment: ★★★★☆

[Added 1-5-12]Full run on Panasonic 3100mAh netted a 76minute runtime to cut-off, noticeable dimming occured in the second half even by eye alone. The test was fan cooled and head of light peaked and held around 30C

Sanyo unprotected 18650, start at 4.18 down to approx 3v (cutout flashed by torch) was a few minutes under an hour on full.

20C = 68F

45C = 113F

55C = 131F

60C = 140F

 

 

This is a few seconds after the light dropped output and started flashing, the battery voltage was 3.05 seconds after removal (so you'll have to guess the voltage underload(sag) it cut-off at im afraid)

Light Output: ★★★★☆

 

Output is going to be similar to any other C8 driven to 2.8amps, which is probably the sweet-spot to keep heat to a manageable level and minimise sag. Other cheaper C8s may compare favourably for short time driven at 3+amps but I have bigger lights for hot-rod performance that will not suffer with the heat/time constraints thus caused.

Unprotected Panasonic 3100mha @4.185vdc h=2.78a m=0.88a l=0.15a

Protected Senybor 2600mha @4.164vdc h=2.79a m=0.88a l=0.14a

DMM calibrated

 

Summary: ★★★★★

 

A light that imo earns a stunning 5 star review due to the value for money, it is simply the EDC budget light of this size/battery class. I urge anyone in the market for a C8 to stump up the extra few dollars and plump for this one, you wont regret it!

 



 

Thankyou for reading Smile

Please rate the light if you own it :

that's all I do..put the original image you want mouse off for in the first field..then hit advanced and click the box..then put the original image in the mouse off field and put the other picture in the mouse on field..click save or insert or whatever it says..I find I need to refresh the page before it actually works though so maybe you had it right and just had to refresh..

Great review of what I consider to be one of the best budget flashlights that I own.

 

 

Rats, finally sold my 2010 509hp Mustang...now I can buy more lights!

Sold the red one too! Now guess what I drive, doing my penance for 500 hp commuters...

Nice review.

I used to screw in/out reflector for better spot or remove green ring.

I did it all up on a PC but 90% of the time I use my tablet and that's a pita to do anything other than read on. I'm waiting on a Intl-outdoor drop-in for my L2T so I'll do a beam comparison then hopefully, they should be very similar but in a lovely compact P60 Smile

Thanks for a great review, Jeansy. Love that light. Your pictures illustrating tint are something I haven't seen in a review before - nice touch.

Thanks BetweenRides, as you can see not much difference but i was interested how it would turn out.

 

I was just playing with my Fluke 123, connected directly to a XR-E to see if i could measure the flicker induced by the driver at lower modes (refered to by most on here as PWM)

Here are the results with the light details photoshopped onto the display:

As you can see the sample rate and scales were altered to best suit, i am not 100% about the readings and if anyone has advise please feel free to add. It seems to add up tho, the 980 has by far the worst PWM, closely followed by the 3T6, the XinTD is almost not visible. I tested my Crelant 7G5 but could not measure or see PWM(low is not very low tho), the same with the cheapo DX 5 Mode XM-L 501b!

 

Edit: Still cant get the mouse over working Sad

lol sucks man..it can be tricky..

also the nangj has great pwm..great driver..the 980l has the same driver as the uf 3 mode drop-in found at manafont..it's bad pwm, but a nangj can fix it also if it bothers you..luckily for me i'm not highly succeptible to pwm and wouldn't even know to look for it if it wasn't for this site lol..damn you all!

Hi Pok,

I did the same thing with mine when I first got it, until I found my favorite "sweet spot" for the beam.

Jeansy -

Good job and this looks like a great flashlight, especially for the money.

I keep my eye out for XinTD reviews to see if the quality I experienced is consistent across models.  For example; an UltraFire MCU-C88 or the UF- 980L are both top quality pieces but the UltraFire WF-502B is not.  (at least the few I've seen)

This XinTD C8 looks exactly like a Palight and any number of other C8s.  Which is not necessarily a bad thing but other XinTD designs appear to be more exclusive to the brand. (if it is a brand)

Am I making any sense?

I noticed that the XinTD C8 looked more like a generic C8 with the exterior build quality as opposed to the XinTD that you reviewed, which looks top notch quality. I have all the UFs you mention and that is exactly my experience aswell, it seems the 502 gives the other UFs a bad taint, they really are rather good quality.

Perhaps my five stars are generous given the blemishes but for the money I think it truly is the best you can buy.

 

I am still a new (budget) flashaholic and jumped straight in for the powerhouses with a triple XM-L and then super throwers such as my Crelant 7G5 and SF MPP1, Im glad I own these but they have allowed me to appreciate just how well rounded this light is, if I was to own one light now, at present this would be it! The king may not reign long for me tho, if the Intl-outdoor dropin combines with my SF L2T to create what I hope it will.

OK I have given this a quick go but it didn't make much difference, was this on the XinTD or another C8?

I believe they were talking about the XinTD because it is the only one I know that has the screw in reflector.  I tried it myself before and did not notice much difference either.

OK following some questions about the PMW results i achieved here are some more (on low). As you can see the results match others now but also it has shown me how easy it is to get differing results. The PWM is complicated and contains different frequencies/amplitudes thus differing sample rates give different results, perhaps a cheaper meter is easier as shown by the 179 results?

Note the zoomed in waveform on the 123 on the last pic, it is mainly out of shot and i forgot to get a pic of it but at that sample rate the Hz was recorded as different dispite being exactly the same, bar the sample rate. I think it measures the frequency of the content of the 'chunks' (want of a better word lol) in the top pic.

My XIN TD C8 appears to be perfect in fit and finish; no flaws noted. Still the best $32 I have spent on a flashlight. If it would only run on 2 x Cr123 as well as 1 X 18650, it might be the best light on the market up to $50.

Can't say about Xin TD. but my C8 and UF-2100 with Nanjg 105C AMC7135*8, 2.8A installed run on 2xCR123a 3.0V very good, even Uf-2100 runs on Hi (but very! hot). Effeciency of the driver is only about 65-70% (30% is converted to heat of the driver Sad ) with high voltage, but AMC7135 is rated to work up to 7V peak. None died yet.

How how many hours have you run 2xCR123A in the C8 and the UF-2100? And could you estimate how much time the flashlights were on at a time on High mode.

Your efficiency estimations look very good compared to other which have tested 56-70%.

Need to make a run test Smile Not done yet.

Efficiency is not my own measurements. Once I saw an AMC7135 specs table or something like that and just remembered that it is most efficient at 3.9V - 90% and worst at 6V - about 65%.

The 1A driver is 56%, the 1.4A driver is 63% and one chip is 50%. Results are from from this thread on CPF.

UF-2100 is so small and works with 2.8A with 6V, should be a lot of heat, many around the forum get scared of lower watts in bigger lights.

i got my light a few weeks ago. i love it. there was a small speck or nick on the dome of the LED but Hank is taking care of me. he rocks.

i also had a small issue with the reverse spring on the driver and my AW batteries so i had make a mod for that. i just silver soldered a piece of copper tubing in its place with a little silver solder blob where it contacts the battery.... like .140" long overall. i would think the short, stiff spring that comes with the nanjg drivers would have worked perfectly for me so i dont know the reason for the reverse spring.

the fit and finish of my light is flawless. threads are real smooth. love that big brass pill too.

NW is real nice too.

everyone at work is trying to steal it lol.

i too noticed that it is out of stock cause i was showing a friend where to get it.
