    Cheapest and Easiest Wii Sensor Bar

    I need help on powering X5 LEDS from an AC-DC power adapter. The IR LEDS are rated for 940nm and are 1.2-1.5V and they each use 20-30ma current amps.Would a 6V AC-DC power adapter with 100ma work and be safe? I do not want to add resistors. I am trying to get the LEDS to match the voltage and current based on the total amount of LEDS I am using which is X5. IR LEDS 940nm type. Here is the link. Do you sell one like this I can buy in bulk?https://www.amazon.com/gp/product/B01BVGIZGC/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1IR LED - 940nm Infared LED Diodes(1.2V - 1.5V) Rated voltage 1.2v X 5 IR LEDS = 6V TOTAL1.5v X 4 IR LEDS = 6V TOTAL(20-25ma)20 X 5 IN SERIES = 100ma TOTAL ALL LEDS / PERFECT MATCH TO AC-DC 25 X 4 IN SERIES = 100ma TOTAL ALL LEDS / PERFECT MATCG TO AC-DC30 X 5 IN ...

That would be safe on a 6V 100ma AC-DC Power adapter?I do NOT want to add a resistor, I am trying to get the amps and volts to safe levels without adding the heat consumption of a resistor too.
