With four mote sticks at full brightness, what are the Watts and the Lumens?
You’d be drawing close to 500mA, at 5V. I’d say you should expect 90-95% of that theoretical value of 2.5 watts (most examples in the repo will draw 420-450mA to give you an idea).
In term of brightness, I don’t know for sure, but on the numerical pain scale of 0 to 10 I would say ‘ouch’? Does that help ;-)
