Frequently Asked Questions

Thank you for your interest in TheraBulb.  On this page you will find answers to common questions about our products. If your topic is not addressed on this page, contact us through the contact form or via email at support@therabulb.com.

 C

Coating: One of the bulbs is a darker shade of red than the others. Will this make it work better than the others?
No. The red color of the bulbs comes from non-toxic red paint applied to the inside of the bulbs and baked on. The purpose of the red coating is to filter out some of the visible light to keep the bulbs from being overly bright. Occasionally some bulbs get thicker or thinner coats of paint, but this does not affect the near infrared energy output of the bulb.

Coating: I noticed some bubbles in the paint on the bulb. Does this mean there is something wrong with it?
No. The red color of the bulbs comes from non-toxic red paint applied to the inside of the bulbs and baked on. The purpose of the red coating is to filter out some of the visible light to keep the bulbs from being overly bright. Occasionally there are air bubbles in the paint, but this does not affect the near infrared energy output of the bulb.

D

Darkness: Will the bulbs be more effective if I use them in a dark room?
The output of the bulb and its effects are the same whether it is used in a lighted or dark room.

Difference Between Bulbs:  How do the 150W and 250W bulbs compare?
In this chart we compare the Near Infrared Bulb - 150 Watt  and  Near Infrared Bulb - 250 Watt bulbs across 12 criteria.

Dimmer: Can I use this bulb on a dimmer?
You can use the bulbs in a lamp that is on a dimmer so long as the lamp and the dimmer (if a separate device) are rated for the wattage of the bulb before dimming. For the Near Infrared Bulb - 150 Watt, this means the lamp and dimmer need to be rated to operate bulbs with a wattage of 150 watts or greater. For the Near Infrared Bulb - 250 Watt, the lamp and dimmer need to be rated to operate bulbs with a wattage of 250 watts or greater.

Disposal: How should I dispose of a broken or burned out bulb?
TheraBulb bulbs are RoHS certified, meaning they are free of toxic substances.  They require no special disposal. They can be disposed of per your community's guidelines for household light bulbs.

E

EMF: Do these bulbs emit EMF?
They emit very little EMF. TheraBulb bulbs are incandescent bulbs, which emit negligible amounts of EMF. Anything electric will emit some EMF, so while there is no bulb that that emits no EMF, incandescent bulbs emit significantly less than fluorescent, LED, halogen, and other bulb types.

Eye Protection: Do I need to wear anything to protect my eyes when using the bulbs?
We recommend protective eyewear because the brightness of the bulbs can cause discomfort. Most of our customers use tanning goggles.

H

Heat: How hot do these bulbs get?
Laboratory testing has determined that the Near Infrared Bulb - 150 Watt reaches a maximum temperature of 518 degrees Fahrenheit and the Near Infrared Bulb - 250 Watt reaches a maximum temperature of 518 degrees Fahrenheit.

L

Lamp: What kind of lamp can I use to operate the TheraBulb?
First of all, you will want to choose a lamp that is rated to operate bulbs with a wattage equal to or greater than that of the bulb. For the Near Infrared Bulb - 250 Watt (120V for North America) and the Near Infrared Bulb - 250 Watt (240 Volt for Europe, Asia, Africa, Oceania), you will need a lamp designed to operate bulbs that are 250 watts or greater. For the Near Infrared Bulb - 150 Watt - (120V for North America) and the Near Infrared Bulb - 150 Watt - (240 Volt for Europe, Asia, Africa, Oceania), you will need a lamp designed to operate bulbs that are 150 watts or greater. You can usually find the maximum wattage of the lamp stamped on the socket or on a sticker placed on the socket.

If you are interested in the Near Infrared Bulb - 150 Watt - (120V for North America), we recommend the TheraBulb Infrared Lamp with 150 Watt NIR-A Near Infrared Bulb (120V for North America). This lamp is designed specifically for the operation of the TheraBulb 150W bulb. Manufactured of medical grade plastic, the lamp has a sturdy base designed to sit firmly on a table or other flat surface and features a hinged neck that allows you to adjust the angle of the light. The lamp comes complete with a Near Infrared Bulb - 150 Watt - (120V for North America).

If you are interested in the For the Near Infrared Bulb - 250 Watt (120V for North America), the Near Infrared Bulb - 250 Watt (240 Volt for Europe, Asia, Africa, Oceania), or the Near Infrared Bulb - 150 Watt - (240 Volt for Europe, Asia, Africa, Oceania), there are two types of lamps that can operate the wattage of these bulbs and allow you to adjust the direction of the light. These are brooder clamp lights and photographer’s light stands.

Lead: Do these bulbs contain lead?
No. TheraBulb bulbs are RoHS certified. This means that they are free of substances covered in the European Union Restriction of Hazardous Substances Directive 2002/95/EC. These substances include lead, mercury, and Teflon.

Lifespan: How long do these bulbs last?
While the lifespan of the bulbs will vary, we offer a one year replacement warranty. 

Maximizing Bulb Life: How do I keep my bulb from burning out too soon?
Believe it or not, there are right and wrong ways to screw in a light bulb. Screwing the bulb into the socket too tightly can cause it to burn out prematurely. This is because doing so can flatten the part of the socket (an angled brass tab) that makes contact with the bottom of the bulb, and it is this contact that allows the bulb to light up. If the tab becomes flattened, the bulb can burn out too soon.

The bulb should be screwed in just enough for it to stay in place when you release your grip on it. Once the bulb is in this position, stop screwing it in. Screwing it further can flatten the tab.

Mercury: Do these bulbs contain mercury?
No. TheraBulb bulbs are RoHS certified. This means that they are free of substances covered in the European Union Restriction of Hazardous Substances Directive 2002/95/EC. These substances include lead, mercury, and Teflon.

O

Overseas Use: Can I use these bulbs outside of the US?
Yes. TheraBulb has designed all of our bulb and lamp models for use in 110V/120V electrical systems. 110V/120V is the standard for Canada, the US, Mexico, and several other countries. Additionally, we offer versions of our Near Infrared Bulb - 150 Watt and Near Infrared Bulb - 250 Watt for use in 220V/240V electrical systems. 220V/240V is the standard for Africa, Asia, Europe, Oceania, and much of South America. If you are unsure about your country’s electrical standard, click here.

P

Packaging: I received my bulb and the box it came in was dented and creased. Is this a used bulb?
The bulb you received is new and is packaged in TheraBulb’s eco-friendly packaging. These boxes use 40% less paper and, because of their lighter weight, they also save fuel in the shipping process. Unfortunately, what they gain in “greenness” they lose in appearance as they make their way to the customer.

Pets: Are TheraBulb bulbs safe for use around pets?
Yes, as described above, our bulbs are free from toxic substances. However, you will need to observe the same safety measures you would when using any other heat-producing electrical device around pets.

Plants: Can I use these bulbs to grow plants?
No. You will need a full spectrum bulb to grow plants. TheraBulb is not a full spectrum bulb.

R

Replacement: Can I use a TheraBulb bulb to replace the bulb in my infrared lamp?  You can use TheraBulb as a replacement bulb so long as the socket is type E26 / E27 and the TheraBulb is the same size as or smaller than the original bulb.  If it is shorter, you may need a bulb extender. For more details, click here.

No. TheraBulb bulbs are RoHS certified. This means that they are free of substances covered in the European Union Restriction of Hazardous Substances Directive 2002/95/EC. These substances include lead, mercury, and Teflon.

Testing: Have these bulbs been tested to confirm that they emit near infrared?
Yes. An independent laboratory, ISO 17025-certified lab verified the wavelength output of the bulbs as well as their irradiance and maximum operating temperature.

U

Uniqueness of Product: Are TheraBulb bulbs re-branded versions of less expensive bulbs?
No. Our bulbs are manufactured for us, in our own factory.

V

Vitamin D: Does this give the same Vitamin D benefits of the sun?
No. TheraBulb NIR-A Near Infrared bulbs do not facilitate the synthesis of Vitamin D in the human body because they do not emit ultra violet light.

W

Warm Up: Do the bulbs need to “warm up” before they become effective?
No. The bulbs begin emitting visible light and near infrared energy at full output as soon as they are turned on.

Wavelength: What is the nanometer rating on these bulbs?
Independent laboratory testing has verified that TheraBulb bulbs emit energy in the 390 nm to 1000 nm range. This includes the visible light spectrum (390 nm – 699 nm) and the near infrared range (700 nm – 1000 nm).

Wavelength: What is the peak output of these bulbs?
Independent laboratory testing has verified that TheraBulb’s peak energy output is at 750nm. The Near Infrared Bulb - 150 Watt emits 9.59% of its total energy output at 750nm and Near Infrared Bulb - 250 Watt emits 9.94% of its total energy output at 750nm.

Why TheraBulb: How are TheraBulb bulbs different from infrared bulbs that are much less expensive?
TheraBulb is an infrared incandescent bulb. It’s one of several brands of infrared incandescent bulbs on the market. These bulbs can be used for a number of purposes, including heating an entryway, heating food on a buffet, keeping newly-hatched poultry warm, and heat/light therapy. TheraBulb products are designed for heat/light therapy. What this means is:

  • They bear the CE mark and are RoHS certified, indicating that they are free of lead, mercury, Teflon and other hazardous substances and meet specific safety standards. 
  • They are accompanied by a safety precautions guide that specifically pertains to human use. 
  • We, the manufacturer, offer technical support – excluding medical advice – related to the use of the bulbs.
  • TheraBulb bulbs have been independently laboratory tested to provide verified information on:
    • Intensity / Irradiance: the concentration of emitted energy at a given distance from the bulb
    • Output Distribution: the percentage of each kind of energy emitted by the bulb
    • Maximum Operating Temperature

If you are using the bulbs for heat/light therapy, intensity and output distribution data tell you how much infrared energy the bulbs are putting out. This is something a medical professional would need to know in order to tell you how to use the bulb (how long, how far away) to achieve the purpose of the therapy.

If you are looking for a bulb to heat up your front porch or keep a chef-carved ham warm; however, the less expensive bulbs are probably all you need.
