The bulb voltage must match the lamp fixture and electrical supply; a travel plug adapter changes plug shape only and does not convert voltage
The Sauna Fix lamp kit is sold with a bulb-voltage choice of 120 volts for North America or 240 volts for the EU, UK, Australia and other regions, and its 240-volt country cords are sold separately. The lamp itself ends in a grounded US-style plug. This guide covers the 4 conditions that must all match before a Sauna Fix lamp runs on 220 to 240 volt service.
The European cord page lists 4 conditions and states that the cord is used only when all 4 are true: the Sauna Fix lamp is configured for 220 to 240 volt use, 240-volt heat lamp bulbs are installed, a compatible grounded wall outlet is available, and the local circuit is appropriate for the lamp load. The British and Australian cord pages list the same 4 conditions for their own outlets.
The bulb page states the reason: bulb voltage, fixture voltage and supply voltage have to agree. The 240-volt bulb page puts it as a rule, never mix 120-volt and 240-volt bulbs or fixtures, because incorrect voltage can damage the lamp, bulbs, sockets, cords or electrical system and may create a fire or shock hazard. The cord pages state the fixture condition directly: the fixture and its internal wiring must be intended for 220 to 240 volt service. Their electrical safety line is to have a qualified electrician verify the fixture, bulb voltage, plug, outlet, grounding and circuit before use.
The Sauna Fix Heat Lamp 4 Bulb Set, 240 Volts International Only, is $131.96 and contains 4 bulbs, matching the standard 4-bulb fixture. The page states that the bulbs emit across approximately 550 to 3000 nanometers, from visible red through near, mid and far infrared, with substantial output in the near-infrared range, and that they produce radiant heat as soon as the lamp is switched on.
The bulbs are not compatible with a 120-volt Sauna Fix fixture, and a 120-volt bulb does not go into a 240-volt fixture. The North American bulbs are sold as a 120-volt 4-bulb set. The 240-volt page puts a 4-bulb fixture at approximately 1 kilowatt-hour of electricity for each hour of operation; to estimate a session's cost, multiply your local price per kilowatt-hour by that hourly figure. The page also recommends replacing an aging set together, because 4 matched bulbs give more even brightness and heat across the fixture.
Each cord connects the grounded US-style plug on the Sauna Fix lamp cord to 1 country's wall receptacle. All 3 are $39.99, approximately 24 inches long, and about 1 pound, with shielded construction that the page describes as an aluminum layer beneath the outer covering. The cord is designed to keep the lamp's grounded connection intact from the lamp to the wall, and it does not change the electrical frequency.
Europe uses more than 1 outlet standard, so the European cord page asks you to confirm that the supplied plug matches the country where the lamp will be used. The United Kingdom uses a different plug standard and takes the British cord, and Australia takes the Australian cord; all 3 are for 220 to 240 volt service. Connect the cord only with the lamp off, unplugged and cool: inspect both cords and plugs, seat the US-style lamp plug fully into the cord, plug the other end directly into a grounded wall outlet, and route the cord away from hot guards, sweat and walkways.
When the lamp is configured for 220 to 240 volts, the 240-volt bulbs are installed and the correct cord goes into a compatible outlet, the cord pages state that a step-up transformer is not required. They also warn against adding one casually: an improper converter can overheat, fail under load, interfere with grounding or damage the lamp.
A travel plug adapter changes the plug shape only, not the 220 to 240 volt supply. The 240-volt bulb page states that it does not convert voltage, and the cord pages add that it may not provide the required grounding or current rating. The same pages exclude extension cords, multi-plug boards and ungrounded adapters unless they are rated for the full lamp load and permitted locally. The Sauna Lamp Rebuild Parts Kit page makes the same point for repairs: a rebuild does not automatically convert a lamp from 120 to 240 volts or back.
The cord pages set an inspection before every sauna session. Do not use a cord whose insulation, plug, pins, shielding or either of its 2 connection ends are cracked, loose, bent, burned or frayed. Keep every plug and connection away from sweat, water bottles, damp floors and wet towels, and away from bulbs, guards and heaters. The cord must never carry the weight of the lamp or stay stretched tight, and it is disconnected by gripping the plug body, not the wire.
If the plug or cord becomes hot, the instruction is to turn off and unplug the lamp immediately and not use the system again until the cord, outlet, fixture and electrical load have been inspected. The lamp page sets the seating distance at roughly 18 to 30 inches from the bulb surfaces, and the bulbs page recommends protective eyewear rated for near infrared, such as the IR Guardian glasses included with the lamp kit.
Needed for 220 to 240 volt use: a fixture configured for that supply, the 240-volt 4-bulb set, and the cord for your country.

No. A plug adapter changes the plug shape only and does not convert voltage. The lamp must be configured for 220 to 240 volts with 240-volt bulbs and the country cord.
No, when the lamp, the 240-volt bulbs, the cord and the outlet all match 220 to 240 volt service.
The United Kingdom typically uses a different plug standard; use the dedicated British cord when a UK-style plug is required.
About 24 inches, and it weighs about 1 pound.
About 1 kilowatt-hour per hour of operation for a 4-bulb fixture, by the bulb page.
