Received in 30 days. Can not see any difference between 445nm and 460nm except the voltage. One LED chip had a bent over leg. Thought first it was a broken leg. I ordered only 5 pieces, I want 5 perfect ones. It was very well packaged so seller sent me one with bent pin with knowing it. Voltage is about 2.98V to 3.10V at 300mA constant current, depends on how hot the chip is (the hotter the less voltage at constant current. If you drive them with constant voltage, current will increase with heat and it can then exceed its maximum power ratings). In the description it says 300-350mA, so you can reach 1W. A real datasheet would be nice.
