    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:This is a boost driver for when you need to increase your battery's voltage in order to drive multiple LEDs in series. I am using it to drive 3x sku.4516, for a total output voltage of 19.8V. The power source is six 18650's wired as 3S2P (11.1V). This is for m... Read more

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:This is one of the few boost drivers on sale. I prefer boost drivers because generally they allow the use of higher capacity 18650 batteries in place of 16340 batteries. This is a CC driver so should, in theory, work with less than 5 LEDs in series - provided... Read more

It was brighter than I thought it would be on high. Cons:Strobe and SOS OtherThoughts:This driver barely fits in the neck of A M*g C tube. I used it in a D. 5 XR... Read more

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:The only driver on DX capable driving 4-5 LEDs in series from 5 - 8.4V. 800mA are better then 1000mA, because of 15W power, 80% efficiency and no thermal management Cons:no thermal management (except the coil) driver is getting warm-hot OtherThoughts:on high,...
