Richard, is this the same driver that came with the D4 v1? I have a v1 and I’d like to change to v2 if possible. I don’t mind getting the same driver with v2 firmware and replace it.
You can swap the MCPCBs directly, with NO SPACER required. I had read some comments stating that a spacer is necessary, but doing the measurements and actually building some lights with the MTN Quad MCPCB it works fine without any extra spacer needed.
Could I put 4 XP-E2 Green emitters on your board and run em on the FET or would I have to reduce direct drive through PWM to keep from smoking the emitters like I did the Lee Filter I tried?
Maybe use the 18350 tube and a lesser cell to keep max current in check?
It can't be the capacitor. Maybe we flashed it with the wrong firmware or something because there is not OTC on that 15mm 7135 board, so the capacitor will not affect the memory.
Hi Richard, what turbo timer option should I choose on the 17mm fet +1 driver with the D4 firmware? I wish to have the same configurable temperature step down as the D4.
I just received my first order from MTN and I am just really impressed with the quality of that L2 host. To be honest I bought the scratch and dent version and I don’t think anyone would know if I had said it was one of the first quality lights. I had to look at it for a bit and finally found 1 scratch on one of the fins on the head. The only thing I would suggest is throw in a couple screws to screw down the MCPCB with. But if that is all I have to worry about we are all good. Thanks a lot!
My apologies the screws had just really gotten hidden in the package. along with 2 centering rings and an extra spring. Thank you.
Has anyone offered to do any flashing of the first batch of D4’s…?
I bought 3 of the 1st batch and not quit up to flashing skill level so just wondering if there’s been any offers, can pay cash for flash or barter…?
We will reflash them if you pay shipping. Flashing is easy, getting the driver out without breaking anything can be difficult. Are you sure that you got the first firmware? We only sent out a handful of lights with V1 firmware. Quite a few with what I would consider to be V1.9 firmware (newer thermal throttling, but for more uses it is as good as V2. If it blinks in the middle of the ramp then you do not have V1 firmware.
