Just completed a very simple conversion from the terrible 1amp East-092B to direct drive. It is very simple.
1) Strip light
2) Cut the circuit board ends of the wires going to LED
3) Remove circuit board
4) Used nippers to remove all circuit boards/resistors from driver. Goal was to sever all modes and the failed 1amp current path.
5) Opened up pre existing hole in center(ish) of board to 1/32”. The hole ends up in the spring on the opposite side.
6) Opened up one of the edge holes to 1/32”, this notched the side of the board for wire clearance
7) Feed + white wire through center hole and solder to spring
8) Feed - black wire through side notch and solder to circuit board outer ring
9) Reassemble
Pulls 4.1 amps on TF 5,000mah protected batteries. Very bright. I intentionally reused the stock small led supply wires to limit current. Replacing them with larger would probably dump too much and fry the led. Basically 2 simple solders and you have a 1 mode Direct Drive light. When using my 2010 I don’t seem to care about med or low.
Crude? YES but bright and no blinky modes, only HIGH. Perfect. Only downside is that it isn’t dark yet!
