Smart Chasing Lantern LED Filament Light Module, Blue, 3V, 40mm Length
Autables 40mm Dynamic Chasing Effect LED Filament is a compact COB LED module designed for decorative lighting, DIY electronics, model making, indicators, creative lamps, signage, and custom lighting projects. This LED filament creates a moving/chasing glow effect where the light travels from one end to the other instead of illuminating fully at once.
With blue light output, 3V operating voltage, and low current consumption of less than 20mA, it is suitable for low-power and battery-powered lighting applications. Its compact 40mm size makes it easy to use in miniature lamps, decorative displays, hobby projects, indicators, and custom electronic designs.
