# Diffused 5mm Fast Flashing RGB LED - 10 pack - Flashing Effect

**Type:** Product page · **SKU:** ADA680 · **Brand:** [Adafruit](https://core-electronics.com.au/brands/adafruit-australia)
**Page:** https://core-electronics.com.au/diffused-5mm-fast-flashing-rgb-led-10-pack-flashing-effect.html ([markdown](https://core-electronics.com.au/diffused-5mm-fast-flashing-rgb-led-10-pack-flashing-effect.html.md))

These are very interesting 5mm diffused RGB LEDs - instead of having 4 pins to control 3 LEDs, they have only two leads - power and ground. When powered, the LEDs...

## Pricing

- **Price:** $8.80 (inc GST) — $8.00 AUD, exc GST
- **Quantity discounts:** 10+ $7.76 (exc GST) · 50+ $7.60 (exc GST)

## Availability & dispatch

- Available with a lead time — expect dispatch between Sep 02 and Sep 07.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA680:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA680:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

These are very interesting 5mm diffused RGB LEDs - instead of having 4 pins to control 3 LEDs, they have only **two leads** - power and ground. When powered, the LEDs perform a flashing effect with all the colors. See the video below for the timing and look. There is no way to change the 'program' or rate, its burned into a little chip that is inside the LED itself. If you need to have an RGB perform a particular arrangement, [check out Adafruit's RGB LEDs that you can easily control with a microcontroller](https://core-electronics.com.au/diffused-rgb-tri-color-led-common-anode.html) They also have a [version that's a 'slow fading' RGB](https://core-electronics.com.au/diffused-5mm-slow-fade-flashing-rgb-led-10-pack-slow-fade.html) color cycle.

They're fairly bright LEDs, Adafruit guess its something around 1000 mcd total. They do diffuse nicely so you can the color changing from any angle. The forward voltage of the whole LED is about 3.4VDC but you can drive them from [a lithium coin cell like a CR2032](https://core-electronics.com.au/cr2032-lithium-coin-cell-battery.html) and they'll just be a little dimmer. Adafruit don't have a datasheet showing the current draw over different voltages and colors but at the 'rated' 3.4V its approx 20 mA and at 3.0V its approx 10mA.

Comes in a pack of 10 LEDs! Although the LEDs are all the same shape and have the same basic program, **due to manufacturing variables they will not sync together** - they'll slowly drift in and out of sync.

## Technical Details

- 5mm diffused RGB LED
- Two leads
- Power with 3-3.4VDC
- Current draw: 10-20mA depending on voltage and displayed color
