Create your own custom bottle lamp with this DIY bottle lamp adapter. There is no complex wiring involved and as the flex is attached to the side rather than the base of the adapter, no need to drill into a glass either. It couldn’t be easier, simply twist the adapter into a bottle opener with a bung diameter of 17 – 19mm. Then add the shade and bulb of your choice, plug the adapter in and you have a stylish and custom table lamp. The intelligent design that makes it so easy to create also makes it effortless to reuse. Imagine you have decided to redecorate and your once light-colored scheme that went so well now doesn’t match. No problem, you can simply untwist the lamp adapter from the bottle and affix it to a new one with no hassle.
