The XHP70.2 8,000 Lumen BLF-GT With Beam Shots!!!!!!!

Texas_Ace:

Glad to hear it! The GT series is supposed to be a conversation starter to say the least lol.

Remember that if you double click it goes into turbo which is brighter then the top of the ramp.

Yeah, that’s the icing on the cake… The top of the ramp is impressive enough. The dim spill makes it a lot more useful than some would believe at lower settings. I hadn’t hiked in over 20 years, but as my health has been improving a friend invited me to join their group. Needless to say, the GT70 is an ice-breaker in more ways than one! Great work on the overall design. to the involved parties!

I’ve managed to open my GT and am needing a conversion kit.

I’m purchasing from nealsgadgets.com and wondering if the conversion kit includes the 2x Cell Carriers or do I need to purchase them additionally? Do I need the Cell Carriers or can I use the ones for the XHP35 HI version?

There’s a selection to choose from:

- 1*XHP70.2 LED CW+1*Centering Ring+1*TA Driver - $55.00

- 1*XHP70.2 LED NW+1*Centering Ring+1*TA Driver - ”

2*Cell Carriers - $28.00

What exactly am I meant to purchase?

Is Nealsgadgets the cheapest and only option?

The battery carriers are an extra $28 cost option if you want them.

I only know of Neal’s gadgets or maybe Lumintops store that offers these parts. I’m not sure which is cheaper.

That’s about all I know. Sorry.

Edit, Lumintops store doesn’t seem to show the conversion kit so I guess Neal is the only source.

PiercingTheDarkness · 2019-02-18T10:30:29.000Z

Thanks for your input.

So I don’t actually need the carriers, the ones used in the XHP35 HI version will work fine?

Right, both leds are the same 12v.

That’s great news. Thank you

Hi all!

So I’ve read this entire thread. I’m ready to convert my XHP35. I’ve ordered Neal’s kit, CW version. I guess it comes with the battery carriers, though I don’t need them. Is this going to be a direct drive board like the second one Matt used in his video?

I’ve watched Matt’s video. I’ve never modded a light, but have enough skills to do so I think. A simple soldering iron and solder and flux should be all I need right? I don’t want to screw anything up, so ANY Tips or advice prior would be much appreciated from anyone in here.

I’m super stoked to do this and can’t wait to try it out.

Thanks in advance everyone!

Texas_Ace · 2019-02-23T19:51:29.000Z

Yeah, with the kit you basically just have to solder the LED power wires and you should be good to go.

Be careful to clean the LED carefully with alcohol before testing. even the smallest spec can kill the LED.

djans1397 · 2019-02-23T19:54:54.000Z

Ok. Thanks much.

Is this DD?

What’s the verdict on dedoming? Good, bad?

Texas_Ace · 2019-02-23T19:56:58.000Z

Yes, the driver that comes with the kit is a FET based driver.

I personally don’t like dedomed LEd’s but it does throw a lot further that way.

djans1397 · 2019-02-23T20:02:15.000Z

Parson my ignorance, FET driver is a direct driver?

Texas_Ace · 2019-02-23T20:03:34.000Z

Correct

It would be a good idea to get a very small amount of good thermal compound like Arctic Silver5 or similar.

Neal’s kit does not include the carriers. They are a $38 option.

Make sure you can get the upper head and bezel loose. This might be the hardest part of the conversion.

I apologize if I am using this forum incorrectly. I simply wanted to post a question regarding my BLF GT70. It seems that it won’t ramp up to the full high mode .When I ramp up it barely gets any brighter . And when I get double click for turbo it comes up to what seems like the current ramped up mode. All batteries are fresh and fully charged. And I’ve attempted to a factory reset. I’m not sure if the issue lies in the programming or of something is broken internally . Plz helps

Texas_Ace · 2019-06-16T15:37:31.000Z

If it maxes out around a few hundred lumens, then most likely the 2nd channel is not coming online for some reason.

Did it ever work properly?

The most likely cause is a bad FET. Luckily this is fairly easy to replace if you have any soldering skill. If not then a replacement driver should get it working. Lumintop should be able to get you one.

PiercingTheDarkness · 2019-06-17T10:47:11.000Z

I assume you’re using good brand cells?

Theodore41 · 2019-06-17T11:21:33.000Z

Hi vestureofblood .
I have a Astrolux MF04S instead of the BLF XHP70.2 and a Astrolux MF-04 as well. Is there a possibility to have a similar update?I have a BLF-GT as well.
So,if I wanted to push one of them,so as to be like yours,which one is better and what parts I had to find?

I have not had an MF04S apart so I cant say for sure about boosting the driver. I am gussing you will find a buck driver inside so if you take a picture of the board components and post it,there may be a sense resistor that can be changed on it to give you a bit more current. As for getting more throw, you could definitely slice the dome off your LED and get a huge jump in performance.

If the Astrolux driver can not be boosted, Lumintop doe sell a driver and LED kit for the BLFGT to convert it to 70.2 and the mosfet. BLF GT70 Conversion Kits – Nealsgadgets

JasonWW · 2019-06-17T20:48:29.000Z

The MF04S uses a Boost driver (6v to 12v mcpcb). You can change sense resistors to boost output, but Turbo run times drop from around 1 minute down to 30 seconds. Most modders just replace the driver to get a better user interface. With NarsilM or Anduril you have full control over the thermal step downs.
Lexel makes a regulated driver for it and I also think a FET driver.
See this thread.

What kind of extra performance are you looking for? More distance on the MF04S? Slicing the dome will do that. The MF04 and GT are already maxed out for distance.
