This is a placeholder topic for “Diffused White 10mm LED (25 pack)” comments.

Need some really bright and big indicator LEDs? Adafruit are big fans of these 10mm diffused white LEDs. They go easily into a breadboard and will add that extra zing…

Hello are these lights able to run 24/7, do we need to install a resistor with them?

Hey @Matt293448, welcome to the forums!

For the most part, these are your run-of-the-mill LEDs, they’ve just been “sized-up” to 10mm.

You’ll need a resistor to limit the current. The recommended continuous current for this LED is between 10mA and 20mA, so you’ll need to choose a resistor value that keeps it within that range.

You should have no problem running this device 24/7.

Hope this helps!

Thanks mate, this is new to me as we are looking at improving the quality of the leds we use, do we just solder the resister on, or do you sell a pre made one with a resistor? Would this be ok to wrap heatshrink around and run fiber optic strands onto it to disperse the light through the fiber optics? alternatively do you have a better way of doing that?

Hi @Matt293448

For the resistor it would need to soldered to the negative lead of the LED, the resistor that you use will depend on the input voltage that you have, I like this calculator from Digikey for working out what resistor would be needed.

I would recommend using a non diffused LED, usually they will output light in a narrow field out of the LED itself, which would work better for Fibre Optics.

We do also stock Fiber Optic Light Source - 1 Watt - White | Buy in Australia | ADA4168 | Adafruit | Core Electronics that is purpose designed for use with fibre optic cables that are 4-5mm in diameter.
