It is toroid type, Its a pretty rubbish driver , just low & high with strobe. I just bought one to see what was actually in it…
I did see a 6v driver that looked sorta ok 4.5A
I only dropped the current to 4A in the other one because its thermal path is so terrible
The other one you Posted doesn’t look to bad either
There is not a huge selection sadly, Djozz posted a good test on the emitter XHP50.2 Lots of potential if you can actually power it right up
