With a lifespan of 15,000 hours this bulb is going to last! Looks fab with our wooden lamp base for a retro feel. It uses high efficiency LED technology to produce a long lasting, low heat and low power consuming light, using high quality acrylic tubes and illuminated using a laser-generated pattern creating a vintage look. Amber tinted glass and 1800k LED create a very warm relaxing glow. This ingenious bulb is also 3-step dimmable, which means you can flick the switch off and on again to dim down the brightness using a normal switch, no dimmer switch required!
