Need help 16W and 30W driver input 12V

Hi guys,

Im new at this and trying to understand all your abbreviations of things, but Im not there yet.

I have a 11.1V Li-po 20Ah batterypack

I need two types of drivers for two different emitters.

Both can be on/off or 2 mode 100/50%

I need one driver that has an output of 12V @ 1,33Ah

And the other one on 12V @ 2,5Ah

They are going to be used with a single emitter.
If it is possible it would be greate if it was max 26mm diameter round.

Is there any good efficient drivers like this?

Sorry, I can see that I posted in the wrong forum. Could Admin move it?
