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 my primary bike light, which I guesstimate outputs 1000 to 1200 lumens.
I am getting about 8... Read more
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 there is sufficient voltage differential. I'm planning to use this driver to replace the buck ... Read more
Easy to use
Able to handle 2 li-ion cells NO memory
Simply too hot. Low Efficiency of 67.5%. 7.4V input (8.6W) only results in 1.845A @ 3.15V output (5.81W). This means that 2.79W of energy will become heat in the driver which makes the driver heat up really bad within seconds. I couldn't put my finger on the driver for more than 2... Read more
Driver seems to be well built. Its very easy to use, and on 6 nimh cells it drives 5 XRE R2s well. It was brighter than I thought it would be on high. Strobe and SOS This driver barely fits in the neck of A M*g C tube. I used it in a D. 5 XRE R2s with the 18mm DX reflectors SKU 14598 (4 pack so you will need 2 packs) Wired the leds in sires made a light ... Read more
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 no thermal management (except the coil)
driver is getting warm-hot on high, 4xQ5, 2p2s 18650 LiIon
results in an efficiency of ... Read more
Great for D.I.Y. project 5 mode driver.
Good range for Cree emitter from P4 to Q5.
Boot up the voltage up to more then 19 volt. ( Test on a electronic meter )
Good range from battery power up to 8.4 voltage include Li-on, Nimh and Alkaline etc.Include rechargeable battery.
Test with 2 pc. 16850 3000mah battery, more then 50 minutes on high mode.
