Even lonoceans himself said that his driver is always 90+ efficient, not 70.

[ GXB172 - 50W Single Cell 17mm Boost Driver! ]

Over the past some two weeks and a half a lot of things has happened so I'd thought I'd share some here. It all started from when I found some time to do a proper write-up for my GXB17 driver which you can read in detail on my webpage here. …

47 W out with 89% efficiency when driving 6V LED.
