Every Mosaic Age lamp we make is built for one electrical standard, and it matters more than most buyers realize. If you're wondering whether your handmade Turkish-style mosaic glass lamp can handle a different country's outlets, this voltage guide gives you the honest, specific answer instead of a vague "it depends." We'll cover what 110V and 220V actually mean, why the US and most of the world don't match, and exactly what to do if you're moving, traveling, or shipping a lamp abroad.
Browse the full mosaic lamp collection to see current styles, colors, and prices, every one built for a standard US outlet.
Every Mosaic Age lamp is built for standard US 110-120V outlets only, not for 220-240V systems used across most of the world. A plug adapter changes the shape of the plug but not the voltage, so it will not make a 110V lamp safe on a 220V outlet. If you're traveling or moving abroad with your lamp, you need a real step-up or step-down voltage converter rated for the lamp's wattage, or you should leave the lamp plugged in at home and pick up a local-voltage bulb and fixture at your destination instead.
What voltage do Mosaic Age lamps use?
Every lamp Mosaic Age sells is wired for standard US household current: 110-120V at 60Hz. That's the electrical standard in the United States, and it's the only one our lamps are designed and tested for. Our own product FAQ states it plainly: our lamps are designed for US 110-120V outlets, and using one anywhere else would need a plug adapter, a voltage converter, and a bulb rated for that region's voltage.
We're not going to tell you our lamps quietly support both voltages, because they don't. Each lamp ships with a standard US plug, a warm-white LED bulb rated for US current, and a cord built for a US wall outlet. That's the whole spec, and it's worth knowing before you order one for a home outside the US or pack one in a suitcase for an international trip.
110V vs. 220V: what's the real difference?
Voltage is electrical pressure, the force pushing current through a wire. A 110-120V system pushes less pressure than a 220-240V system, so appliances built for each are wound and wired differently inside. According to the US Department of Energy, homes in the United States run on 110-120 volts at 60 Hz, while most other countries use 220-240 volts at 50 Hz.
That 50Hz vs. 60Hz difference matters too. Frequency is how many times the current switches direction per second, and it affects motors and some electronics even when the voltage happens to match. A simple LED lamp like ours is far more voltage-sensitive than frequency-sensitive, but the mismatch is still real and it's not something a plug shape alone can fix.
Why does the US use 110-120V while most of the world uses 220-240V?
It comes down to history, not a technical advantage either way. Early electrical grids in the US were built around 110-120V because that's what early incandescent bulbs and DC systems handled well, and once utilities built out that infrastructure, the country never had a reason to switch. Many other countries electrified later, after 220-240V systems proved more efficient for sending power over longer distances with less loss, so they built around the higher standard from the start.
Neither number is objectively "better" for a home lamp. A 220-240V system moves more power through thinner wires with less energy lost as heat, which is useful at a grid level, but it also means a shock or a wiring fault carries more risk per volt. For a small lamp like ours, the practical difference is simple: it's built for one system, and mixing systems without the right equipment is where the danger comes in.
Can you plug a 110V mosaic lamp into a 220V outlet?
No, not directly, and not with a plug adapter alone. Plugging a 110-120V lamp into a 220-240V outlet pushes roughly double the electrical pressure through wiring and a bulb that were never built for it. That typically means an instantly blown bulb, a scorched socket, or in the worst case, an electrical fire, not a slow decline you'd catch in time.
This is the single most common mistake travelers make with small electronics and lamps: they assume a plug adapter, the little piece that changes the prong shape, also changes the voltage. It doesn't. A plug adapter is a mechanical fix for a mismatched socket shape. A voltage mismatch is an electrical problem, and it needs an electrical fix, which is a real voltage converter, not an adapter.
Plug adapter vs. voltage converter: they are not the same thing
These two get confused constantly, and mixing them up is exactly how lamps and small appliances get damaged abroad. A plug adapter only reshapes the prongs so they physically fit a different wall socket. It does nothing to the voltage or current flowing through the cord. A voltage converter or transformer actually steps the voltage up or down, from 110V to 220V or the reverse, so a device built for one standard can safely run on the other.
Travel-electronics retailers like Ceptics, which specializes in international adapters and converters, draw this same line clearly: an adapter solves plug shape, a converter solves power. If you only pack an adapter for a 110V-only lamp and plug it into a 220V outlet, you have not protected the lamp at all, you've just made it possible to plug it into the wrong power.
Converters also come sized by wattage, and a small mismatch there causes its own problems. A converter rated for less wattage than your lamp and bulb draw together can overheat or fail, so check the combined wattage of your lamp and bulb against the converter's rated capacity before you rely on it.
Taking your mosaic lamp abroad: a step-by-step decision guide
If you're moving overseas, hosting a lamp in a vacation home outside the US, or just don't want to leave a favorite piece behind, here's the real decision process, not a guess.
A simple four-step way to decide what your mosaic lamp needs before it travels.
Step 1: Check the label. Every Mosaic Age lamp is rated for 110-120V, 60Hz. There's no dual-voltage switch to flip on ours, so treat that spec as fixed.
Step 2: Check your destination's voltage. A quick search for "[country name] electrical voltage" tells you whether you're headed somewhere on the 110-120V standard (much of North and Central America, parts of the Caribbean and Japan) or the 220-240V standard (most of Europe, Asia, Africa, and Australia).
Step 3: Compare the two. If your destination also runs 110-120V, you likely only need a plug shape adapter, no converter required. If it runs 220-240V, your lamp needs a real voltage converter to run safely, not just an adapter.
Step 4: Decide what actually makes sense. For a short trip, a step-down voltage converter rated above your lamp and bulb's combined wattage works. For a permanent move, it's often more practical to leave the lamp on 110V power at home and buy a bulb and lamp built for local voltage at your destination instead of converting long-term.
Does the light bulb need to match the lamp's voltage too?
Yes, the bulb matters as much as the lamp's wiring. Each Mosaic Age lamp ships with a warm-white LED bulb rated for US 110-120V current, screwed into a standard base. That bulb is built for the same voltage as the lamp itself, so replacing it with a 220-240V bulb while running on US power, or the reverse, creates its own mismatch even if the lamp's cord and wiring are otherwise fine.
A 220-240V bulb run on 110-120V power will generally just glow dim, since it's getting less pressure than it needs, an underwhelming result but not usually a dangerous one. It's the reverse direction that's the real risk: a 110-120V bulb pushed by 220-240V power draws too much current and can flash out or fail immediately. When you replace a bulb, match its voltage rating to the actual power source it's plugged into, not just the socket size.
Warning signs of a voltage mismatch
If a lamp is running on the wrong voltage, it usually tells you fast. Watch for a bulb that flashes bright and burns out within seconds of being switched on, a warm or hot plug and outlet cover to the touch, a faint burning smell near the cord or socket, or visible scorching around the plug prongs. Any one of these means stop immediately, unplug the lamp, and don't plug it back in until you've confirmed the outlet's actual voltage.
A lamp that's correctly matched to its power source, whether that's a US 110-120V outlet directly or a properly sized voltage converter, should never run hot at the plug or flicker unpredictably. If yours does either, treat it as an electrical warning sign, not a quirk to ignore.

Frequently asked questions
Is a Mosaic Age lamp 110V or 220V?
Every Mosaic Age lamp is built for standard US household current, 110-120V at 60Hz. We don't sell a 220-240V or dual-voltage version, so treat that spec as fixed for every lamp in our collection, including the bulb it ships with.
What happens if you plug a 110V lamp into a 220V outlet?
The lamp receives roughly double the electrical pressure it's built for, which usually blows the bulb instantly and can scorch the socket or start an electrical fire. This isn't a slow failure you'd catch in time, it typically happens within seconds of plugging in.
Can I use a plug adapter alone to use my mosaic lamp overseas?
Only if your destination also runs on 110-120V power, like Mexico or Japan, where a plug adapter handles the shape difference and the voltage is already close enough. If your destination runs 220-240V, like most of Europe or Asia, a plug adapter alone will not protect the lamp, you need a real voltage converter too.
What's the difference between a plug adapter and a voltage converter?
A plug adapter only changes the physical shape of the prongs so they fit a different wall socket, it does nothing to the electrical current. A voltage converter actually steps the voltage up or down so a device built for one electrical standard can run safely on another. You often need both together when traveling internationally.
Does the light bulb need to match the lamp's voltage, or just the socket?
The bulb's voltage rating matters as much as the lamp's wiring. A bulb built for 110-120V power run on 220-240V current can fail immediately, while a 220-240V bulb run on 110-120V power will just glow dim. Always match the bulb's voltage rating to the actual power source, not just the socket thread size.
Can I buy a 220V bulb and use it in my Mosaic Age lamp instead of converting the whole lamp?
No, that doesn't solve the underlying mismatch. The lamp's internal wiring is still built for 110-120V current, so running it on 220-240V power damages the lamp itself even if the bulb happens to be rated for the higher voltage. The fix has to address the lamp's power source, not just the bulb.
Why does the US use 120V while Europe uses 230V?
It's a historical accident, not a technical advantage either way. The US built its electrical grid early around lower-voltage systems that worked with early incandescent bulbs, while many other countries electrified later and built around higher-voltage systems that lose less power over long-distance wires.
Is US household voltage 110V or 120V, which is correct?
Both terms describe the same real-world US household circuit, and you'll see either used interchangeably. The US Department of Energy describes US homes as running on 110-120 volts at 60Hz, so 110V and 120V both fall inside the normal range you'll measure at a standard American wall outlet.
Will a UL listing tell me a lamp's voltage rating?
A UL listing confirms a product met a safety testing standard, it doesn't by itself tell you the voltage. You'll find the actual voltage rating printed on the lamp's UL label, its base, or the manufacturer's product page or FAQ, separate from the UL mark itself.
What size voltage converter do I need for a small mosaic lamp?
Add up the wattage of the lamp and its bulb, most Mosaic Age lamps ship with a low-wattage LED bulb, then choose a converter rated comfortably above that combined total. Undersized converters can overheat or fail under load, so it's worth checking the wattage printed on your lamp's base or included documentation before buying one.
