I’ve seen the e21 2800k test on zero air with a 18650 3000k mah battery
I’d like to know how much runtime would I get with Nichian519a 4000k and a 5000 mah battery, and does the light run flat at medium and high modes before I spend money.
I already own lights that can do 300 lumens
I’m looking for something with these LEDs that can handle 500-800 lumens without burning up
