Great work. In my short time here i really came to love the stuff you do.
The 7135 is for high efficiency in the lower modes - right?
Does this make for significant gains in 2+S Zener lights, since we are burning 50-100mW all the time trough Zenner and 200R?
Just want you to know that this driver, loaded with ToyKeepers A6 firmware, works beautifully in a BTU Shocker with 3 XP-L V5 1A emitters. I rearranged the cell carrier to run in parallel and bypassed springs, used my last 2 of djozzās phosphor bronze springs for the main contact points, and it does 4095 lumens OTF.
Pretty intense strobe in the hidden loop.
Thanks again Alex, nicely done! Perfect fit for the BTU Shocker.
Built a second version of this driver tonight. Zener modified with an extra 10uF cap on the Zener, itās running 12.6V from 3 series LG HE-2 cells to 3 of the 9V MT-G2 emitters. OTF lumens is 8742. And this one getās hot after about 60 seconds!
The beam profile is a fat hot spot with nice spill, putting a whopping amount of nice creamy white light out. And these MT-G2ās look really good in the big tri-reflector as well!
Iāve got the Toshiba dual sided MOSFET with a nice coil of copper soldered to the top side, Iām thinking this oneās pulling in the 15-18A range, but havenāt measured it yet. Judging from the heat flowing into the massive head on this light, itās definitely making some power.
Essentially simple when youāre not using the kitchen sink stuffā¦
This one was in the BTU Shocker with triple XP-L emitters in parallel, hence the triple 18ga wires at each LED terminal. I replaced it with a Zener modified version to run 9V MT-G2 emitters.
Those extra pads are the kitchen sink spoken of earlier. For thermal and such. I donāt really understand that aspect of it, but as a normal driver it works just fine. Maybe Iāll figure out just what the kitchen sink has to do with lighting and implement some good ācleanā fun.
Does this look right? I canāt get it to work properly, no matter what firmware I use it gets stuck on turbo. Iāve used a zener and replaced the diode with a 200ohm resistor.
Iām using it for a MT-G2 build.
wow. Thatās very strange. My gut tells me it has to be something with the firmware, but youāve already tried different ones so Iām stumped. Hopefully somebody else can chime in.
