Need Cool Host for 2x18650 Laser



Hello, I am new to this hobby and need some suggestions.

I am looking to put together a 2W 445nm laser. My driver requires at least 6v and 1.8A draw or less. I was thinking 2x18650 batteries meets this requirement the best.

My question is: What is a good bang for the buck Cool looking host that makes people go wow? If you were to have a blue laser and could have any host for under $40 what would you get?

Thanks, Sparkles
