There’s lots of videos on YouTube showing how to do it. Check out Old Lumens and AdventureSportFlashlights in particular.
I haven’t tried it myself either, but I probably will one of these days.

That’s actually very good! I’m happy now. Won’t be buying the 30q set then. At least not for now. Thank you Nkresho!
Thank you too Newlumen! Very much appreciated. Let’s put them 35Es to work!
P2 bin is the highest right? That’s good. What does the “C” means?
Yes, P2 is the highest bin.
The C means it will have a little green in the tint sadly.

Will the dedoming worsen this? Or will make it better?

It will tint shift warmer and a bit yellow / green. So it will get worse, how much I can’t say as all LED’s seem to dedome a little differnt and will depend on the person.
If you plan to dedome I would go with the CW or replace the LED with something of your choosing while you are doing it.

Now I’m really in doubt. I don’t like CW in any of my lights. I have a DX80 just for the sake of raw output, but really hate the tint. I wish I could get two MCPCBs with the different LEDs to test it out. I have a L6 with the N2 3A and really like the tint.
teacher: Texas_Ace:In other news I just got word that the Neutral white GT70 will be ready soon along with the conversion kits.
The final Neutral while LED will be a 5000k XHP70B-3C-P2 led

:+1: … Looks good except possibly for that “C” part. …
……. Oh well, can’t have it all I guess.

Yep… what TA said.
Take a look at the tint chart below. Notice the B & C tints are above the dotted black line (BBL). They both lean toward the green tints. The further above the line the greener.
The A & D tints fall below the BBL and lean toward a rosier tint. The further below the BBL the rosier.

I would say the best option is to simply order an LED you know you would like from another source in your case and install it before converting the light.
I think KD has some A and D tints available IIRC.

Hmm I see. My L6 is 3A. Maybe that’s why I like it. Well. Now I will just do a little more research to try and decide it.
Thanks teacher.

Yeah. Maybe I’ll need to learn how to reflow LEDs. I’ll try and find some different LEDs on china. Thanks TA

This is what I do to basically every light I get anyways, I think I can count the lights with the factory LED’s on one hand lol.
I retested the 30q in addition to the 35e. Both were fresh off the charger at 4.20v Each battery set had less than 5 cycles of 5 mins or less on them.
I let the light cool about 15 mins between tests. Light engine was cool to the touch at the second test start.
Same carriers used both times as well (both the correct GT70 carriers with the thicker aluminum) compared to the OG GT carriers.
30q
Start lumens 8,388
30 second lumens 7,14735e
Start lumens 7,848
30 second lumens 7,087Startup was about 6% lower with the 35e
30 seconds was about 0.8% lower
Thanks bro… your lumen specs are really helpful.
I was a little surprised that the output tapered so close after just 30 seconds. Initially the 30q have quite the spike in output, but they fall off pretty fast.
Single emitter with so many cells had to be a factor too. Differences between, say, a 30q and a vtc5a are pretty noticeable on a triple emitter single cell light. It’s more when you approach the current limit of the high drain cells that you see the higher output from them.
Happy to help.
It also has a lot to do with the heat. The first 30 seconds of losses are largely a matter of things heating up and that causing a reduction in output if I had to guess. The 30Q gives it more power but it also heats up more, so it seems to balance out.

Right, if we assume the GT70 draws 10A at 12v, then with 8 cells it’s only 5A per cell. If you only use 4 cells it’s 10A per cell.
The difference in voltage sag between the 35E and the 30Q is not so big at 5A, but at 10A the gap gets bigger.
I think 4A and 8A is probably closer to reality, but I use 5 and 10 because we can see that in this load chart from HKJ.

Even with the sony vtc5a, the lumen drop fast from 0 sec to 30 seconds.
Lothar: Texas_Ace:Those that want the bags, batteries and other add-on’s I would recommend waiting to place your order until it is sorted out.
Texas_Ace:Ok, I got a minor update on the bags and caps. Basically they will not be available with the group buy BUT they will ship them separately later once they are in stock. So watch for these later.
Texas_Ace:Ok, The 30Q cells are officially live on the Lumintop website
Ok, so just checking: I can order the BLF GT70 CW with batteries, lens cap and strap so long, and then order the bag separately and they will ship that for free to the US?
I’m not in a hurry, so I don’t mind for everything to be available to send them out at once. Should I maybe email Leo and arrange this?Yes, you can now place an order for everything except the Bag which will take several weeks to be produced. Everything available now will start shipping next week if all goes well.
On the bag you can order it at a later date and yes, shipping should be free then as well seeing as it would ship in a separate box even if it was ordered now.
This is not true according to Leo at Lumintop. Here is what he replied today when I inquired about when my caps and straps would be shipping:
Jim,
We cannot organize the accessories together when I arrange the shipment because you paid twice. We will send refund of covers and straps to you soon.
If you need the accessories, pls buy them from banggood directly.
Pls kindly be noted.
Leo
This makes no sense because on 08/13, I asked Lumintop about shipping the items together and was told:
Hello Jim,
Yes, you can play the additional order for the head cover and shoulder strap, and we will ship them together with the GT70 flashlight.
Thank you
Victor
And then on 08/17 when I had order issues with their site, I inquired and was told:
Thanks for the message.
Regret that your order 900109233 was wrong. For the code is only for GT70 orders, not for accessories.
So we would like to change the price to $28 which including the shipping fee, and after complete the payment, we can ship these together with order: 900107837
Any questions just feel free to contact us.
Thanks
Lumintop team
I paid for the accessories nearly two weeks before the light shipped. The irony is $28 was $6 more than my total which I assume was to cover shipping costs. I don’t see where I can get 4 caps and 2 straps on Banggood for $28 shipped. I realize these are accessories, but I am still making a purchase from Lumintop. Is there any BLF pull that can help get this straightened out? I don’t mind paying for shipping, but there is clearly a considerable difference in price on accessories between our BLF/Lumintop buy price and Banggood. I feel really uneasy now spending another $220 for the NW version with such fluid transactions.
Wow, I’m glad I waited and didn’t get a BLF GT yet, where can I order one of these beasts at?
