Review: Black Shadow Terminator 4*U3/4*18650

Ya, I need something between them for proper fitting and not to scratch my Terminator so much.
Combine two will be easiest one. I can’t locate standard L shape or + shape adapters or screws to combine 3,4 or 5 Terminator. Might need to do custom build to combine more. Anyway, 5000 lumens will be really bright as my single Terminator already can light up everything in front of her.

I believe that I fix the problem with the banned song and now it’s a mute video but you can watch it

Please someone from US inform me that everything is OK
thanks

The video works great for me. Super job on that light! Works great and looks professional. 8)

Thank you Johnny

The Terminator is being sold online by a local dealer in our country and I’m setting my sights on this beast. I can’t wait to get my hands on one. Thank you for this review. :beer:

this is still on my want list… any word on the u3 version and or if the possible “under driven” issues (when compared to spec) are worked out yet?

maybe i will pm the forum rep on cpf and see if he knows anything about this and or xml2 versions

I can tell you that Black Shadow engineers have a 1.5m Integrated Sphere that they test on. They test 3450 with a U2 version and over 3700 with the U3 version. It is very likely that IS are not linear in their outputs and that with my smaller IS (14") it is not as accurate with the extremely bright lights like this one. I read over 3200 lumens with my IS. My IS is not ANSI certified but is calibrated pretty dead on with lights under 2000 lumens and is exactly in agreement with Match's and E1320's OTF numbers for the same exact regulated light. The Terminator could very well be putting out the claimed number.

Another review on CPF did not test the U3 on an IS but they did do a lux reading and my U3 light returned the same exact number as his did. Build quality is exceptional and apparently consistent. I will say that people claim brightness to the eye is not linear. My SRK puts out around 2300 OTF lumens (IIRC) and I will tell you that the Terminator is not only brighter, it DOMINATES the SRK as you can see in my indoor photos. I really do not doubt the 3500 OTF lumens claimed by Black Shadow. Their numbers for the U3 were actually closer to 3800 in their tests.

I would love to calibrate my IS against a regulated and ANSI certified light that puts out 3000 OTF lumens or more. Once calibrated against that light I'd retest the Terminator and see what I get. I'm sure it would be higher than what I tested now. At the price the dealer mentioned is selling them I wouldn't walk, I'd RUN and grab one ASAP before the price changes. This light really is this good in my experience.

Thanks for the info… I emailed their vendor to see when the u3 will be sold.

What lux reading do you get and at what distance? I’d like to compare it to mine.

I don’t think that the sphere size is an issue. I get the same values using the internal sensor and the external sensor (that sees 1/100 the light of the internal one) on my 16” sphere. Also, the numbers that I get with my 15,000 lumen light ( 15,000 Lumen Bridgelux C9000 Light Engine ) match Bridgelux’s published data quite well.

Just picked one up for $118 shipped to Canada brand new for the U2 version. Knowing that once you get that bright, a few hundred lumens is barely noticeable to the eye, I didn’t Need the u3 version. For the price, it sounds like a fine piece of light! And it should arrive around when my tk75 arrives so I can’t wait to compare!

I am also curious on lux numbers of the U2.

damn, word is out. might not be able to wait, johnny :wink:

I really love the form factor of this light. I am holding out till xml2 though

I haven’t measured the U2 lux number (if I did I must have them written down somewhere. Just need to find them). I can’t remember the exact lux recorded for the U2 @ 1m but IIRC it worked out to around 426 yds? Don’t quote me on that though.

U3 numbers as follows:

Output (U3 1C emitters):
Mode OTF Lumens
Firefly: 0.15
Low: 489
Medium: 1685
High (initial) 3174
High (10-15 seconds) 3044
Lux
Lux @ 15ft 2380
Lux @ 1m 59292
Distance @ 0.25lux 487yds

Thanks for the numbers… very helpful

May I know where you see the under driven issues mentioned? Is it one of the member here got one that is not bright enough, I forgot who he is already.
Mine is definitely driven very hard. It got so hot to touch in 10 minutes. Of course this is very subjective to judge by touching heatsink.

I think it was Texaspyro who only measured around 2200 on his.

Yes, and two other examples (allegedly U3’s) are at 2400 lm. My tailcap current readings back those numbers up.

As my Terminator is between Fenix TK70 and Trustfire X100(3*26650), so she should be within 2000 to 3000 lumens. Again, this is very subjective as different person or different led tint will have different perception.

How to do a simple relative lumens comparison without sphere?
