Hello fx-sabers! I'm finally back after a long absence from the hobby and ready to build another saber. I decided to go with a prizm v5.1 for this install and just wanted to get the final approval before I proceed.
I usually only build with crystal focus so I never had to worry too much about resistors but of course this is different. I used a DC bench power supply and Erv's tutorial for finding Forward Voltages of High powered LED's.
Here's what I got.
LED: Green Green White Tri cree
Forward Voltage of Green 1: 3.05 V @ 900 mA
Forward Voltage of Green 2: 3.19 @ 900 mA
Forward Voltage of White: 3.16 V @ 500mA
Using R = U/I and P = U*I
Green 1: R = (3.7 - 3.05)/0.900 = 0.72 Ohms P = (3.7-3.05) * 0.900 = 0.59 Watts
Green 2: R = (3.7 - 3.19)/0.900 = 0.56 Ohms P = (3.7-3.19) * 0.900 = 0.46 Watts
White: R = (3.7 - 3.16)/0.500 = 1.08 Ohms P = (3.7-3.16) * 0.500 = 0.27 Watts
Using these calculations is how I came up with the resistor values for the High powered LED in my wiring Diagram:
Please let me know if anythings out of place I really appreciate it! Thank you!
