## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA6216:1` (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/ADA6216:1.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

This warm-white glowy letter is made out of COB (chip on board) LEDs, often seen in 'Edison-like' LED bulbs, arranged in different patterns to give a bright, warm lighting effect. They're made of dozens of micro LED diodes that are bonded together on a stiff metal backing and then coated in silicone for protection. Even though the LEDs are only placed on one side, the PCB substrate is very thin so it glows out the back too (although a little dimmer)

Since the LEDs are in parallel, you only need 3V to light 'em up - Adafruit recommend current limiting with a resistor to let max 100mA through.

**Please note that these are NOT flexible!** However, they have a nice uniform glow all the way around and do an excellent job of mimicking a tungsten-like filament.

Arrange a group of them into words, their light weight means they can easily be glued to surfaces, sewn to fabric, or tied with fishing line. Because they're just a 'big long LED' you can PWM dim them easily.

Simply power up with 3V by connecting to both ends - the cathode negative side will have a little - symbol on the PCB. If it doesn't immediately light up, try connecting the other way around, no biggie. Compatible with [Arcade Button Quick-Connect Wire Pairs - 0.11" (10 pack)](https://core-electronics.com.au/arcade-button-quick-connect-wire-pair-set-of-10-pairs.html) or you can solder/clip to the tabs at the bottom.
