Can't get enough current for 1W Luexon LED even without resistor
Trying to power a 1W Luxeon star LED. It says: Forward Voltage: 3.5V,
Forward Current 650ma. So I tried a 3.6V battery with a minimal resistor. Very low current. Then I tried without the resistor but still only about 100ma current. In order to get 650ma to flow through the LED I have to raise the voltage to about 11V and of course I already blew the LED. So... how can I get 650ma while only using 3.5V. Seems like my battery has too much internal resistance. Thanks much for your help. |
