Kosnic Lighting
A 4.2W clear LED filament lamp in the GLS A60 shape, with an E27 Edison screw cap and 4000K output. Dimmable on compatible LED dimmers, rated for 15,000 hours with CRI 80 or above. Ideal for offices, garages and work areas.
Kosnic's FA4.2D-ES40 pairs the look of a traditional bulb with LED efficiency: a 4.2W GLS A60 lamp with visible linear filaments behind clear glass, an E27 cap and 4000K cool white output. It is well suited to offices, garages and work areas.
Fit it with a compatible trailing or leading edge LED dimmer and confirm smooth dimming on site; no approved dimmer list is published for this range. Expect around 15,000 hours of use and energy savings of up to 90% over a tungsten filament bulb. Its A60 envelope matches a standard household bulb, so shades and fittings stay as they are. Our LED bulb buying guide explains caps and colour temperatures, and more GLS lamps are in stock.
