Bah, if we only did rated current we’d leave a lot of lumens unused with most of the LED’s we use here. I totally understand if it’s for longer runtime, but you’re definitely not going to damage anything running over 1A.
Here’s a test of the colored XP-E2’S by djozz. Don’t take my word for it. (yes, I know, remove a 7135 chip to get it right at the output peak, but I generally recommend batteries with higher mah ratings and lower current capability with the red ones I sold which tends to lower the actual current it’ll pull to around 2.8A. Usually 3400mah Panasonic’s)
