TheraBulb Infrared Bulbs vs Other Heat Lamps: What’s the Difference?
TheraBulb vs Other Infrared Heat Lamps
Compare clear vs red bulbs, wattages, and real-world usability to choose the right infrared setup.
If you’re comparing infrared heat bulbs, you’ve likely come across a mix of clear bulbs, red heat lamps, and specialty infrared brands. While many options look similar, there are important differences in how they perform and how they’re used.
This guide breaks down the key differences between TheraBulb and other infrared heat lamps so you can choose the right bulb for your setup.

Quick Comparison Table
Here’s a quick side-by-side comparison of common infrared bulb categories.
| Attribute | TheraBulb | General Purpose Heat Lamps | Other Specialty Infrared Brands | What It Means |
|---|---|---|---|---|
| Bulb type | R40 | R40 | R40 | Standard heat lamp size |
| Socket type | E26, E27 | E26, E27 | E26, E27 | Same base as household lightbulb |
| Wattage options | 150W, 250W, 300W | 125W, 250W | 150W, 250W | More flexibility |
| Technology | Incandescent | Incandescent | Incandescent | Produces heat + light and infrared |
| Zero-EMF | Yes | Yes | Yes | Preferable for EMF-sensitive |
| Measured Output Data | Independent lab tested | Limited | Limited | Make informed decisions about use |
Specifications are based on available product information.
What Actually Matters When Comparing Infrared Bulbs
Most infrared heat bulbs share basic specifications like size, socket type, and incandescent construction. What actually separates them is how their output is measured and how that output performs in real-world use.
The most important factors to understand include:
- Temperature: Do you want a product that produces heat? If so, how hot would you like it to get?
- Wavelengths: Does the product emit energy between 650nm and 1000nm?
- Spectral Distribution: How much of the total energy output is red light vs near infrared?
- Peak Wavelength: What wavelength carries the largest percentage of output?
- Irradiance: How concentrated is the energy at a given distance?
- EMF: Does the product emit EMF and how much?
Understanding these factors allows for a more meaningful comparison than simply looking at bulb appearance or brand name.

Choosing the Right Wattage
TheraBulb offers incandescent bulbs in three wattages: 150W, 250W, and 300W, and each offers advantages as follows:
- 150W is useful for targeting a specific area on your body, if you desire moderate heat, or if you would like a larger selection of compatible lamps
- 250W is the most common and versatile choice for many users, providing high irradiance and high heat output
- 300W provides maximum heat output and is ideal for targeting larger areas
What Independent Reviews Show
250W infrared heat lamp bulbs from TheraBulb and seven other brands of general purpose and specialty infrared bulbs were evaluated by an industry publication. The study compared brands for irradiance, light uniformity, and overall value. TheraBulb's 250W bulb was ranked #1 for irradiance and light uniformity, and #2 for overall value, outranking both specialty infrared brands and all but one of the general purpose brands.

Frequently Asked Questions
What is an infrared heat bulb?
An infrared heat bulb is an incandescent bulb designed to produce radiant heat and near infrared output.
What wattage should I choose?
150W, 250W, and 300W bulbs offer different output levels depending on your setup and coverage needs. TheraBulb also offers lower wattage LED bulbs,
What’s the difference between clear and red bulbs?
Functionally, clear and red bulbs are the same. Both emit red light, other visible light, infrared energy, and heat. All of the heat, light, and energy output is produced by the filament. The role of the glass shell is to protect the filament. TheraBulb, like other manufacturers, chooses to make our glass shells red to dampen some of the non-red visible light. Having clear or red glass or lighter or darker red glass is unrelated to the bulb's production of heat, red light, and infrared.
Do these fit standard sockets?
Yes. TheraBulbs fit the same sockets as a standard household lightbulb. The standard socket in North and Central America is size E26 and, in other parts of the world, it is E27.
How many bulbs do I need?
That depends on your setup, the distance from the bulb, and the area you want to cover. Try out the TheraBulb Infrared Coverage Calculator to help determine which bulbs you need.
