Email seller choice of 50-pc bag multiples for availability.

Any combination. Let me know.



* 1/4W Resistors could support approximately 1 to 5 LEDs (in parallel).                    

* 1/2W Resistors could support approximately 1 to 10 LEDs(in parallel).                   

* Metal Film resistors are very stable compared to Carbon Film resistors.                

* Carbon Film resistors Ω-value vary as it heat up and affect desired performance.  

* Always use serial resistors to power LEDs, unless powering with 3v button cell.
