BLF GT (preliminary) modding thread

Yes, most get higher readings are 15-20m.

If you do not then that is usually a sign that there is too much particulate in the air, be it humidity, dirt, dust, pollen ect.

I was thinking in driving the XHP-70.2 LED at 12v not 6v, but I have decided to wait until a better driver is available…

Speaking of said better driver. I have the parts incoming to test the prototype XHP70.2 TA driver for the GT next week if all goes well.

First in line when you start selling…

Also getting a prototype XHP70.2 mcpcb to test as well. :sunglasses:

Really pressing for them to make these for modders.

Thanks Ta , this is awesome !


Lux reading at 7 meter throwing distance for BLF GT.
1.163Mcd which give a throwing distance of 2157 meters.
.

Measured at 20 meters. 1.153Mcd

Thrunite TN42.
Measured at 10 meter 701Kcd

TN42 should be doing 750-800.
I would recommend investing in a real luxmeter.

NO 750Kcd to 800Kcd is much much too high for a non mod TN42.

Where did you get that from? Highest number I’ve seen is 728… The rest hover around 700.

You’re right, my bad, it’s 700-750.

Any suggestions?

I see 720Kcd from my TN42.

Read above, but the LX1330B is the best budget luxmeter.

OK,I’ve got it right now from Amazon.de.

I would get the “real” LX1330B (Dr. Meter brand) , but shipping + import fees is 29$ extra !

Why do you say the others aren’t real.
Do you have a reason to believe they are different?

Dr. Meter released the LX1330B , and later the other no-name LX1330B appeared . I don’t know if the internal components and it’s calibration are the same or not .

The one that TLF tested and found good was actually no-name:

The first test of the XHP70.2 driver for the GT went well tonight. We just need to figure out how to bypass the carrier button top springs.

Some tweaking is needed but at least it works. More will come as I have time.
