The Kosnic FRA4.2D-BC27 is a 4.2W frosted LED filament lamp in the classic GLS A60 shape, with a B22 bayonet cap and warm white 2700K light. It has frosted glass that softens the filaments into an even glow, and draws just 4.2W.

This version is dimmable, so it can sit on a circuit fitted with a compatible LED dimmer. Kosnic does not publish an approved dimmer list, so check dimming performance on site. Kosnic rates it at 15,000 hours, and it renders colours at CRI 80 or above. It is a like for like swap in size for the A60 bulb it replaces.
