I have the Tiablo A9 and A10-G. Aspherics apart, the A10 easily out throws the A9.
To get the most output from these lights you have to run them on 2 X 16340 instead of a single 18650 but the difference is only slight.
The A9 has a stock reverse clicky which I don't like and the A10 has a forward clicky, much better.
The A9 is £75 whereas the A10-G is £135 and I can't quite see why the A10-G is £50 more?
If a project of mine goes to plan I should have the furthest throwing A10 in the land!! I had an older A10 that I am converting to direct drive and hopefully it will be well over 50,000 lux?
HTH,
Steve.
