25mm to 18mm adapter first buy this exact light with the cree xhp70.2 led link: https://www.aliexpress.com/item/32960591645.html?spm=a2g0o.productlist.0.0.354c57d6LRjpKL&algo_pvid=f7c2dc24-8071-43bf-a7a3-ea29aa477bc6&algo_expid=f7c2dc24-8071-43bf-a7a3-ea29aa477bc6-9&btsid=74df947f-af6d-435c-8cb2-2ef7aeb99903&ws_ab_test=searchweb0_0,searchweb201602_1,searchweb201603_60 Then buy this exact driver from adventure sport lights: Select the 6 VOLT driver option for this to work with this light. https://asflashlights.com/-diy-parts/75-10-amp-capable-17mm-led-driver.html remove weak driver from flashlight and replace with the new driver and my adapter which will hold the driver center for optimal position for the batteries positive post. (requires soldering two wires to the board and this also requires soldering a strand of wire from the negative side of the adventure sport driver to the edge of the aluminum housing to complete the ground circuit for your batteries) Fill the void underneath with heat sync cement. It will take an entire tube but it is necessary. update: This light WILL have low voltage protection as long as you dont use more than two cells or two 3.7 volt batteries. For the best results purchase two high quality large capacity 18650 lipos for this project and you will need a charger. You can purchase this with the light but the batteries are not the best. They will work tho. The adventure sport driver has 24 programmable modes including turbo timer which is a heat protection circuit. There are other drivers that will work but the housing is very shallow so the 4 dollar xhp drivers barely fit. I actually made one work but it is just friction fitted inside the housing and that light gets hotter way faster than the adventure sport driver because I still had room to fill the void with heat sync cement on the adv. sport driver.
