3V~8.4V 5W Cree 5-Mode Circuit Board for Flashlights (16.8mm*6.3mm)

Pros: I used one of these, along with SKU 5937 and a spare Cree XR-E P4 emitter, to make a P60 drop in module. The driver is a perfect fit and pretty easy to fit. The five modes are very useful to conserve battery life-when needed. This would also make an ideal replacement for a broken driver in any torch using single XR-E Cree and 17mm driver card. For the price you can not go wrong.

Cons: Wires attached to the card are very small and a bit tricky to solder for a novice. Does not come with any instructions.

Other: Does exactly what it says on the can and is very good value. I would recommend this card.

Pros: I'm using this driver to drive a CREE XR-E P4. The driver looks well made and pretty compact. 17mm is about the right size for most 16340/18650 based flashlights. Driver works with either 1x18650 battery or 2x14340 batteries. With 2 batteries the led is brighter but generates more heat. with one battery the LED says cool but is a bit dimmer. I have also tried this driver with a XP-E R5. This works fine with two batteries but with one battery the medium mode flikers randomly ones the battery drops to 3.7v.

Cons: A bit dim when used with one li-ion.

Other: Good multimode driver for single LED.

Pros: - It's very small and compact - I like the high, middle and low modes - One, or two serially connected Li-ion battery cell is an accepted power source

Cons: - Strobe and S.O.S. modes is useless for me - The factory soldered cables is very thin, the black cable is loosened immediately (not a big a cons, I replaced the thin cables to thicker one)

Other: Good driver, I buy another one in the future.
