I wish I could absorb the knowledge all you experienced modders have. The more I read, the more CooKoo I get. LOL!

I am a green horn in the modding department myself , still learning by the day and trial and error many times.
If it was not for the help and knowledge Dale has given me all along and TomE in the beginning , I would still be scratching my head and wondering what to do…….lol

beam0 ,

The Cree data sheet is showing what they rate the emitters output at the given amperage and is the Cree recommended maximum.

As with any of the emitters that we over drive , From the MT G2 down to the smaller emitters , they all will gain output as the current increases , up to the point that you over drive them too much and then they simply will over heat and burn out.

A good example would be the XP-L HI which has become a favorite for modders. Cree list the max current at 3 amps with a maximum light output of 1095 lumens.

The XP-L HI is overdriven easily up to 7 amps and beyond and when it is driven at 6.5 to 7 amps the output (depending on light , reflector size etc.) will also increase from the listed 1095 lumens to easily 1450 to 1600 lumens. I have modded a good many lights myself with these emitters and see numbers consistently go over the 1500 lumen mark when driven double or more the listed amperage.

There is of course a point when you will get all the lumens you can and then more current , if the emitter handles it, will simply cause even more heat than what is already caused by over driving the emitter , with no more lumen gain.

Of course you will have a lot more heat to go along with the increased current and I am pretty sure a shorter life span of the emitter , although I am not too sure of how much shorter life span , as I have yet to have a properly over driven emitter burn out , with some of them 2 and 3 years old.

Thanks for the info, knew about overdriving single die but thought maybe the MTG2 was different and reached its max point around the max spec.

Got confused because I’ve read where you can’t use a FET driver the 2nd gen multi-die XHP50.2 and XHP70.2 but I think that’s because they’re low VF, but I should have realized MTG2 wasn’t though since my EagleTac MX25L3 MT-G2 is rated at 2750lm (2375 ANSI) which is already above Cree max spec. Not sure how much current it’s pushing.

I’m wondering what the lumen output would be over-driving an MTG2 at 4.9A (w/stock driver in the TC20).

[robo819]

The MT G2 would be more under driven at 4.9 amps I think , you would have to get into the 12 or more amps range to really start driving the MT G2 hard.

As far as the XHP 50.2 or 70.2 you need 6 volts for them so the “standard” FET wouldn’t work if you are looking at the 3 volt FET drivers.

There are a good many Buck and Boost drivers though that will drive the larger emitters much harder than the recommended specs say from Cree.

EDIT: you can actually get the FET with the 6 Volt setup and use them just fine in the lights with the XHP 50.2 and 70.2.
If the forward voltage is too high as it is in some emitters (like the XP-L2 I know for sure) then using smaller gauge wires and limiting the current flow can be done and still stay within the “safe” zone.
The MT G2 I have not messed with but I think it would be the same for it.

[DB_Custom (Dale)]

The MT-G2 is in a sweet spot between 7A and 9A, peaks at around 12A but can take up to around 16A. Max output is around 4300 lumens or so. It’s a huge fat die, color in the output is a favorite of mine, it’s not a thrower except by sheer force, much like the 70, but the 70.2 can certainly make more lumens and throw further as a smaller die (quad die of course, the MT-G2 is considered an array with 72 dies).

Last time I was counting I had some 11 lights with the MT-G2, not sure what I have now. The thing to look at is balance, output for the amperage consumed and a blend of performance vs heat, as well as color of the light to meet preference. So it’s a mixed bag of goods, very seldom is sheer output or sheer throw the be all end all.

My TC20CW arrived. The battery is on the charger. :+1:
I like it and I haven’t put juice to it yet!!

[DB_Custom (Dale)]

Oh Thanks a lot… one of those “must haves” is it? I didn’t order it yesterday, man I have so many lights and have spent so much money lately. Got my hospital bill paid off from the surgery in June and feel good about that, but wow does it ever put a dent in the old thin billfold!

[ARsee]

Haha, yeah. The lights sitting next to me getting charged, it’s plugged into the 3.0 USB port on my desktop, still in the red. I don’t think it will charge very fast. At least not fast enough. I’m being lazy. Both my Opus chargers are full of 18650’s that arrived from Llion Wholesale today. I have an Xtac VC4 not doing a thing. I “should” plug it in huh? LOL! This TC20 is just the right size, not too long, not too fat, obviously at 3800 lumen I assume it will put out a NICE amount of throw and spill. And it’s a Thrunite, it’s got some tooth to the knurling! That is a HUGE plus with me as a feature because my hands are always on the slick/dry side. Edit: Oh, my 6000 lumen Nitecore (edit) TC28 TM28 :person_facepalming: arrived too. The batts are on the charger :+1:

Ow God I’ve tried to resist and seeing this thread was enough for me…….

I did try to order in hkequipment and it is out of stock……. DANM!

If I had to get rid of all my lights and keep only two… TC20 would be one of the two. :heart_eyes:

[DB_Custom (Dale)]

Y’all aren’t helping, I had it in the cart and was in PayPal… AGAIN… and remembered I shouldn’t, closed it out… AGAIN!

In the next attempt you will buy…. certainly

I hate to add this… (just buy one when you can :money_mouth_face: )

…Size-wise, I can’t think of a better host for single emitter / single cell 26650. And I know that for you, in the end, it’s just a host :smiling_imp:

TC28?? Thought this was a joke, then I realized your typo….T M 28

.
Nice light!- BlackShadow Terminator on Steroids! It should have some good throw, needs a handle though… I don’t see a tripod mounting hole on the side where you could adapt one, or am I missing it?

.

EDIT: I see now NHM10 handle fits: (and comes free with it?)

Me too. I also have olight r50 xhp70 as well… this tc20 is very small and bright… what i like about this light is user interface and driver… thrunite driver are bulletproof.

No handle, no batteries. Just the charger. Compared to my TM26GT, this thing is bright I did a comparison ceiling bounce, oh man. Data states 45min on turbo. It gets warm. It was not a free item, but I seen the handle for them. And it does have a tripod mounting hole. :+1:

By the way, (I may have said this already) this Thrunite TC20CW really impresses the heck out of me. It’s just perfect in every way I need it to be. I highly recommend it if you thought about getting one.

This has to tell you something positive, I just bought a 2nd one.

EDIT, a pocket clip would have been a nice addition to the TC20!!!

[DB_Custom (Dale)]

Not sure where you got that about today being the last day, the email they sent me says valid through April 15.

[ARsee]

I won’t say that I’m not confusing it with another offer, I never got the email you mention. I will edit my above!!

TC20 is my first purchase of 2018 & it’s worth every penny! I like it a lot.
