Very bright. Used one of these vs 3 x 3mm standard leds to power the same 3d model. The fact that I didn't have a lower value resistor may also have played into the brightest this used higher value resistor and was brighter. not sure about the power consumption. I need to get new leads for my multimeter to measure the amps.
