Looking for Webcam Software In reply to EmiliaRamos s post on December 19, Camefa have the ic50c and am running windows xp home. It boils down to this, 1 LED's are very sensitive to the voltage used to power them ie, the current changes a lot with a small change in voltage 2 The required voltage changes a bit when the LED is put in hot or cold air, and also depending on the color of the LED, and manufacturing details. In this case, a single NPN transistor is used to create a current sink for an LED. Shop LEDSupply - Free Shipping & the lowest prices on the 3021 & 3023 BuckPuck DC LED Drivers.
