Osram LED ST64 6.5W E27 Parathom Classic 55 Filament Warm White Opal

This elegant 6.5W LED ST64 light bulb from Osram offers all the benefits of LED technology with the vintage style of the classic LED ST64 Edison shape.

Its LED 'filaments' are housed in a opal white glass envelope to recreate the look of traditional incandescent light bulbs. It looks great either hung as a shadeless pendant, or used in a vintage floor or table lamp.

While it might look like an incandescent light bulb, its performance is far more efficient. The 6.5W squirrel cage light bulb emits 730 (equivalent in brightnedd to a traditional 55W light bulb) lumens of warm white 2700K light, perfect for general lighting in homes and commercial spaces. Its long 15,000 hour life means that once the light bulb is installed, it will be years before it needs replacing again.

Features a commonly used ES-E27 Edison screw (27mm) cap/base.

This ST64 is a newer product from Osram and supersedes their old ST64 part codes: 4058075287181.
