Hi everyone, I have a trunite tn40s that I would like to modify. But I need some help. I would like to know what leds I can use. Can I use cree 90.2 or is something else better. Do I have to change drivers or can I use the one that came with flashlight. I am very new to all of this, so I really need help. I am out of work due to a disability. I'm extremely bored so I thought learning about high powered flashlights could keep me busy. Also I'm thinking about purchasing a mateminco 18s just wondering if that's a good purchase. Thanks looking forward to hearing from someone about this.
