Shadow TC750X

Wow only 45mins? Is the 3 minute step down working? Sounds like it must be driven hard…

I like. :bigsmile: Although I’m very suspicious of that step down function raining on my party if I buy it…. :expressionless:

Hi darkside, can you share some information? Do you have a DMM for tailcap readings? Is the stepdown function working? It’s interesting what you’ve said, as the description online portrays a conservative runtime monster:

I’d be interested if it wasn’t softly driven.

A month is gone and still no news on this topic!!! :~

Indeed. Would be nice if those that have this flashlight, either by personal means or perhaps through dealership, would be able to share some information.

turboBB73 promised to do a review of this flashlight “soon” :slight_smile:

It's here now but given it arrived with a bunch of other lights, it's in my review queue. I should have preview in the coming days but in the meanwhile, any q's just ask.

Cheers,
Tim

TurboBB, I’m really interested in any pictures of the dual head and its interior. It’s been at the back of my mind as a project light. Tc350 tube with a pair of 18350’s for one. If LED’s could be swaped out easily? Or the if the bezels are common to the SF thread pitch?

So you wanted a mini-Mjölnir? That's a pretty killer setup (you heard it here first, it's "texas shooter style" ) and I'm quite taken with it:


Two AW IMR 18350's while protruding out quite a bit just fit. However, with this setup, other than being a bit slimmer and tad shorter than the S-L3, it'd be at a disadvantage both output and runtime-wise. It's still pretty cool in this config though and I did verify output to be around 1200lms:

Last pic shows original config vs. XT20



There aren't any grooves in the bezel but I was able to remove it using the palm of my hand and some elbow grease. The lens and o-ring will fall right out with a gentle tap. The reflector however is either glued or screwed and I can't find a way to remove it:


The driver should be accessible but I don't have a tweezer small enough to open the retaining ring. The bezel is slightly bigger than for SF; bottom right pic shows a XENO bezel just inserted in and resting on top of the original bezel, it's too small to fit.

Hope that helps.

Cheers,
Tim

Well that did answer everything, thank you. I was hoping that they had D26 type dropins, but that was just asking too much. Though 2-2 amp XM-L’s sounds pretty good as is with the shorty option.

The XT-20 is P60 compatible. I'll bet you with a bit of prying the TC also is.

I wouldn’t be so sure, the 3 shadow lights I have lack pills, rather the emitter is attached directly to the host itself for superior heat-transfer.

i have the xt20 but was wondering how the numbers you got on the tc750x compared to it? higher or lower output? lux numbers? Im sure they are similar but just wondering if I should own both :slight_smile:

Doing runtime now and confirmed the ~50% step down after 3 minutes. Output is ~1200+ lms but seems to use PWM even on H (just as with XT20 on both counts). Will grab lux later.

Thanks for the information turbobb, I’ve had my eye on this for a while. Stupid question, but I’m assuming it’s 1200+L before the stepdown? So it’s around 600L after?

Correct, 1200+ before stepdown and 600+ after. Hard to pinpoint exact figure due to peaks/troughs from PWM but I'll get a running average when graph is done.

I don’t like that step down feature at all, advertising this light as 1200 lumens is plain cheating then and with that in mind the price is just to high for 600 lumens flashlight, you can get same performance (xml-u2…) fl. for under 20 bucks !!!
I like the shape and overall look and that handy “under the thumb” electronic switch but that step down thing is deal breaker for me…
turboBB, thanks for doing a video review of this flashlight :wink:

So it depends on how you look at it:

cynicists - these jokers are gaming the specs, they claim 1200lms but then it steps down!!!

pragmatists - cool, a 1200lms light that steps down to prevent overheating but I have option to blast 1200 for 3 min when necessary!

The problem w/example you cited is that a sub-$20 XM-L pumping out 600 can't step up to 1200lms (unless you bought another one and taped it together...)

EDIT: I haven't validated yet whether or not you can re-engage H after step down but I suspect you can.

FWIW, even SureFire w/their M3LT doesn't output 400lms for the entire run since it's non-regulated.

But it’s not cheating - it does make the claimed lumens. Bit like a Corvette doesn’t make 505hp all the time either.

It’s like watching a movie trailer on youtube and then buying “expensive” cinema ticket just to be blazed with exciting scenes 3 minutes here and there, and the rest is boring “already seen” story… :slight_smile:
45 bucks is my last offer :stuck_out_tongue:

Thanks TurboBB, not good news if you’re wanting this as a bike light. :frowning: . I’m hoping someone finds a way to mod it and get rid of that pesky stepdown as this form factor is exactly what I’m looking for. Not so bad if you’re just walking around as you can just keep stepping it back up to high mode I assume if you want more continued brightness.
