Review on CHANZON 100Pcs (10 Colors X 10Pcs) 3Mm LED Diode Lights Assortment (Clear Transparent Lens) Emitting Lighting Bulb Lamp Assorted Kit Variety Colour Warm White Red Yellow Green Blue Orange UV Pink by Jeremy Edwards

These are pretty awesome. I got them for Christmas projects and ugly sweaters. They are very bright, 3mm diameter, clear lens (non-diffused), have a small flange and came in a nice anti-static bag.Tested few of them with 5V supply and current limiting resistors ranging from 120ohm to 330ohm. LEDs worked as expected. *Always use a current limiting resistor to avoid headaches*.The flashing/blinking sequence is pre-programmed and can't be changed. The IC does not have a precision clock so when using various LEDs, they will start off with the same pattern but soon after they will be blinking at their own pace, which I think makes them perfect and very affordable for random-lights-changing projects.
