What's N E W ??? these glowing alphanumeric filaments! 🔡💡

Last month we stocked some fun filament shapes, like snowflakes

...or unicorns

...these are easy to use: simply power with 3V like any LED and they glow with a tungsten-eque warmth (but without the 120VAC or burning heat). This week we got some samples of the same COB 'chip on board' filaments but in letters and numbers! Sure we'll have to stock 36 SKUs, but how fun would it be to display custom words? You can drive these in series - 3V total with about 30mA per filament - or parallel - 30mA and 3V * n where n is the number of letters in a row.
