How to Use 28mm Leg LED 5MM Blue Use 3V 20mA
Insert the LED leads through your PCB or panel hole, ensuring correct polarity (flat side of the lens is cathode). Solder the 28mm leads and, if desired, place a small series resistor (10Ω–20Ω) to protect against current spikes. Connect the anode to a 3V supply and the cathode to ground, then verify uniform blue illumination.

Frequently Asked Questions
Can I power these LEDs directly from a 3V battery?
Yes. Each LED is rated for 3V at 20mA and can be driven directly from a 3V battery or regulated supply. For extra protection, you may add a small series resistor (10Ω–20Ω) to stabilize the current.
How do I identify the positive and negative leads?
Although both leads are cut to 28mm, the flat edge on the epoxy lens marks the cathode (negative). The opposite side is the anode (positive) and should connect to your 3V source.
Are these LEDs suitable for humid or harsh environments?
Yes. Built with advanced optical-grade epoxy, these LEDs resist high humidity and temperature, making them reliable for indoor and semi-protected outdoor indicator applications.
