Review: Fasttech 1-4.2 volt single mode driver.

To be honest, I see nothing good about this driver either. I just bought this from Fasttech. https://www.fasttech.com/products/1127402 It pulls 1.5A from an 18650. 1.6A from 2 AA and I if I remember correctly 2.2A from a single AA. I suspect it puts a little more than 800ma to the LED, maybe an amp. I love it and less than half the price. Marc.

The one I have that draws 0.6 A from 2xNiMH must be defective then, or these drivers have a lot of variance...
