On the packaging it says "Use only on 120 volt AC circuits." and on the light-bulb itself it says "120V~, 60Hz and 112mA." The trouble is of course that the light bulb was designed for 120V mains voltage, while in most European countries the voltage is 220V-240V.
Among the 8 variations of residential voltage (100V – Japan only, 110V, 115V, 120V, 127V, 220V, 230V and 240V) there are 15 types of plugs used around the globe with some countries actually using two types of voltage. You can see an up-to-date list of the different residential and three-phase voltages used in each country here.
Japan is one of the few countries using 110V still. That said, for most modern devices, 100V to 130V is no problem and an expected deviation. Similarly, 220V to 240V can basically be considered identical for most devices designed for any of those markets.
But you can, for example, use a 120V product from the U.S. in a 220V country by using a step-down voltage converter/transformer. The voltage adapter and the outlet shape need to match. If not, another adapter will be needed for the two to be compatible. Can I Run a 220V Device Off of a 120V Outlet? While you can step down from a 220V outlet to
If it has 220V, there will be three wires from the power line to your electrical panel, two hot and one neutral. Measuring across the two hot leads, should give you 220V. Which countries use 220V? Typically, either 120-volt AC or 240-volt AC is used. Most countries use 50Hz (50 Hertz or 50 cycles per second) as their AC frequency.
Using 220 might lower the electric bills due to 110v wires being under sized for near the limit use. Most 110 circuits "expect" and are wired for, at most, hair dryers, TVs, coffee makers etc. When you plug in your new fat table saw rated at 110v, 15amp normal running.

can i use 230v in 220v
