I was just hunting around on the internet as usual and I found a great looking and high output LED light that looks very similar to the Thrunite TN30 but it has an external plug on the rear tailcap to charge it without removing the batteries and puts out 3280 lumens.
The X40 uses 3 x XM-L U3 LEDs.
It has a magnetic control ring like the K40, TN31 and TN30 type of lights.
It is at the website neonlaserchina dot com in the High Power Led Flashlight section and it is worth a look and they have another one there and that is the Supbeam K40 that has been reviewed on CPF lately at the link below.
This light is also advertised on the Supbeam website as well.
I do not know if you can buy directly from Supbeam or not yet.
Maybe someone can answer that one in this thread.
I speculate as others do that all of these K40 type lights, TN31 and TN30 have one manufacturer like maybe Supbeam but I could be wrong.
These type of lights all look very similar and there has been much talk about this issue on the Forums lately.
