I picked up the UF A3 from dx two years ago, it had the tank007 driver back then as well. Since then, at some point, I managed to fry the driver (too much playing around with 10440's), so I repaired it with this driver from dx, and upon arrival -unlike the picture on the site- it appeared something was written on it: it is that same old tank007 driver 
.
My output guess of the A3 (see the runtime comparison in my Trustfire Z10 review) is 50 lumens on NiMH and 100 lumens on 10440.
