Filament lamps are bought for how they look lit rather than for output, and Jessar carries them across both technologies. The bulk of the range is LED filament in smoked and clear glass — G40 globes, T10 tubes, Type-A, Type-S and candelabra shapes at 2200K ultra-warm through 3000K soft white, most of them dimmable. Alongside them sit genuine old-fashioned tungsten lamps in radio-tube, squirrel-cage and vanity filaments.
Both are stocked on purpose. LED filament carries the energy story and the rated life, while the original tungsten versions still sell into fixtures and settings where the real filament glow is the point. Wattage, colour temperature, base and dimmability are published per SKU so the two are never confused at the shelf.
This is a display category as much as a replacement one. Exposed-bulb pendants, string lighting and open fixtures all pull from it, which makes it a natural companion buy beside the fixture range rather than a standalone lamp purchase.
