Customers often ask us about using TheraBulb to replace a burned out bulb in a lamp or sauna panel.  The screw base and standard sizing of our bulbs makes them compatible with a range of lamps, fixtures, and panels. In this blog post, we’ll explain what makes a bulb and lamp / light fixture compatible, and what sorts of lamps will operate TheraBulbs.

What Makes a Lamp and Bulb Compatible?

Compatibility is dependent upon socket type, bulb dimensions, and wattage ratings.

Socket Type

There are a wide range of bulb bases, including screw, pin, wedge, and bayonet bases. Each of these is designed to fit into a specific type of socket. The most common and most familiar to consumers is the E26/E27 screw base. This is the type of base found in household lightbulbs and is also the type of base on all TheraBulbs. Therefore, a socket that a standard household lightbulb can screw into is compatible with a TheraBulb.

Bulb Dimensions

TheraBulb incandescent bulbs are sized according to industry standards for shape and size. Our incandescent bulbs are type R/BR and our LED bulb is type PAR. If you are trying to determine if a lamp/fixture is compatible with a TheraBulb, one helpful resource is the manufacturer's literature or web site, which may list compatible bulbs using standard bulb size and shape names, such as those below.  

Voltage and Wattage

You’ll also need to make sure that the lamp / fixture is rated for the appropriate voltage and wattage.

Voltage

Voltage refers to the force of electrical energy in a given system. In the countries comprising North America and Central America, electrical systems voltage is 110V-127V. Products that are marked 120V are designed for use in these countries. Electrical systems in Africa, Asia, Europe, Oceania, and South American operate on 220V-240V. Products that are marked 240V are designed for use in these countries.

TheraBulb offers 120V bulbs in 150W, 250W, and 300W sizes. We offer 240V bulbs in 150W and 300W sizes. We also offer a 5W LED bulb that is universal voltage, meaning it can be used in 110V-240V electrical systems.

The voltage of the lamp/fixture should match the voltage of the bulb you are going to operate in it. Since countries with 110V-127V electrical systems sell 120V products almost exclusively and the same is true for countries with 220V-240V electrical systems, it is unlikely that you will encounter a lamp or fixture that is not designed for the voltage in your country. However, using a 120V bulb in a country with 240V electrical systems will cause the bulb to burn out prematurely and may cause damage to the lamp or fixture. Using a 240V bulb in a country with 120V electrical systems will result in it delivering 50% of the brightness, heat, and near infrared / red light it is designed to. If you are not sure what the voltage standard is in your country, refer to this guide.

Wattage

Wattage refers to the amount of electricity that an electrical product, such as a light bulb, consumes. The wattage rating of a lamp/fixture should be at least as high as that of the bulb you’re seeking to operate in it. For example, a lamp rated for 250W can be used to operate TheraBulb’s 5W LED, 150W, and 250W. It cannot be used to operate a 300W bulb.

Wattage ratings are typically stamped on the lamp cord, stamped onto the side of the socket, or are on a sticker affixed to the lamp or fixture. Exceeding the wattage rating on a lamp or fixture can shorten the life of the bulb, damage the bulb, or damage the lamp/fixture. 

Types of Lamps and Fixtures

Salon Lamps

Single and multi-head lamps are sold through a variety of salon suppliers. These lamps feature a wheeled base, are height-adjustable and allow the head or heads to be tilted to direct the angle of the light as desired. Such lamps are sold complete with a bulb or bulbs. The bulbs are typically a non-standard size and have a neck that is longer than standard bulb. The longer neck allows the bulb to extend into a recessed socket. Customers seeking to replace a burned out bulb in a salon lamp can use a TheraBulb as a replacement bulb, but may need a socket extender. This inexpensive device allows the bulb to get far enough into the socket to make the connection needed to operate the bulb. Socket extenders are sold at hardware stores and online from sources such as 1000 bulbs.com.

Another frequent topic of questions is the use of a mounted light fixture to operate a TheraBulb. There are light fixtures specifically designed to operate infrared / red light / heat lamp bulbs. These fixtures are manufactured to withstand the high (518°F—589°F) heat produced by the bulbs and to vent it safely rather than allowing it to build up inside the ceiling. These fixtures require installation by a qualified electrician. Operating infrared / red light / heat lamp bulbs in a light fixture not designed for this type of bulb is neither safe nor recommended.

Saunas and Sauna Panels

There are a wide range of portable saunas and sauna panels designed for home use in North/Central America and Africa/Asia/Europe/Oceania/South America. Those that use incandescent bulbs are typically sold with the bulbs. TheraBulbs can be used as replacement bulbs in home saunas so long as they are designed to operate bulbs with an E26/E27 base (you can verify this by screwing a regular household light bulb into the sauna while it is turned off) and are rated for wattage that is equal to or higher than the wattage of the bulb.
