3mm red concave LED

(SKU.7-10035/P2) 3 mm concave LED, light color: red.
Pack of 2 pieces.
This LED has a very wide light diffusion angle (120°) and therefore effectively simulates the light of light bulbs. It can therefore be used to replace the bulbs in those situations in which the light guides are located on the right and the other on the left of the bulb. Thanks to the width of the light emission angle, it is able to effectively cover light guides placed, for example, in an orthogonal position.
For correct operation it is essential to use a resistor of approximately 1000 ohm connected in series to one of the power supply poles.
The longer pin is the positive while the shorter one is the negative.
