Host for flat white 1mm

Hello.
Since a few days I play with that led in different hosts.
What host will be the best for that led?
I have Solarforce M3 head with FET driver, also I thought maybe I will put it into Predator 2.5PRO.
What do you suggest?
Thanks,Mike

Convoy L2 or L21A

I could buy Empty L2 host from Simon, which driver from his store should I use?
Mike

The 1mm performs best @4,5 A.
I would buy one 20mm from Led4power, you can select/program the preferred output

You want mine L2 host? Brand New. I Used only to check a few LEDs.
