Number LED Filament - Warm White "1"

This warm-white glowy number 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 '
