This is a great alternative if you want your bedside lamp (or any plug-in lamp) to be dimmable. Just make sure your light bulb is dimmable as well if you're planning to use this product.
US to EU Power Adapter:
If you're in the EU and want to use an US plug-in lamp (or any accessory really), this is your best friend! I used this same one to connect my hair tools and charge my phone/tablet during my time in Europe. I really liked it because its compact and has USB ports ...and mostly because it isn't ugly as most of these adapters are!
