Independent Lab Testing: What You Can't See Makes All The Difference
In a market flooded with options, how do you know which infrared light bulbs for saunas truly deliver what they promise? At TheraBulb, we believe the answer lies in rigorous, independent laboratory testing.
The Invisible Truth About Infrared
When you buy infrared light bulbs, you're trusting that the bulbs deliver something that you cannot see. The human eye can detect visible red light, but near-infrared wavelengths are imperceptible to the naked eye. This presents a challenge: how can consumers verify what they're actually getting?
This is where our comprehensive testing program becomes essential. We test every product line in our bulb portfolio—from our high-watt infrared heat bulbs to our energy-efficient LEDs—in an independent, ISO-accredited laboratory that also serves the U.S. military.
What We Test For
Our laboratory testing verifies four critical factors:
Wavelength Output
This confirms that our incandescent infrared bulbs and LED options actually emit the red light and near-infrared energy they're designed to produce. Without testing, consumers have no way to verify this invisible output.
Wavelength Distribution
Our tests measure exactly what percentage of energy is delivered at each wavelength interval. Whether you choose our 150 watt infrared bulbs, 250 watt infrared bulbs, or 300 watt infrared bulbs, you'll know precisely what spectrum of light you're receiving.
Irradiance (Light Intensity)
We measure the intensity of light at various distances (0.33M, 0.5M, and 1M) to provide accurate expectations for different usage scenarios. Irradiance testing also verifies consistency across production batches—ensuring that every bulb performs to specification.
EMF Emissions
For those concerned about electromagnetic fields, our testing verifies the absence of EMF in our no EMF infrared light bulbs in the incandescent line and measures precise levels in our LED bulbs.
Why Independent Testing Matters
Unlike in-house or DIY testing methods, independent laboratory testing offers several significant advantages:
- Elimination of Bias: Independent labs have no vested interest in delivering favorable results
- Controlled Environment: Testing occurs in spaces where all variables except those being measured are controlled
- Calibrated Equipment: Professional-grade instruments deliver accurate, consistent measurements
- Standardized Protocols: Consistent methodology allows for fair comparisons across products
The Limitations of DIY Testing
Some manufacturers claim to test their heat lamp bulbs for home use with simple handheld devices. While these methods might seem adequate, they typically fall short in several ways:
- Consumer-grade light meters aren't calibrated for the specific wavelengths of red and near-infrared light
- Testing without controlling ambient light leads to skewed results
- Measuring distance with tape measures introduces human error
- Basic equipment can't differentiate between wavelengths
Making Informed Decisions
When you explore our red light bulbs and infrared LED bulbs, you'll find detailed test data for each product. This transparency allows you to:
- Compare products based on your specific needs
- Make objective comparisons across manufacturers
- Understand exactly what you're investing in
- Verify claims with third-party data
The TheraBulb Difference
While many manufacturers make claims about their products' performance, we believe that verified data speaks louder than marketing language. Our commitment to independent testing reflects our larger commitment to transparency and consumer education.
Whether you're setting up a home sauna with infrared light bulbs for saunas or seeking targeted application with our 300 watt infrared bulbs, you can trust that TheraBulb products deliver exactly what we claim they do.
Because in the world of infrared light, what you can't see makes all the difference—and we believe that difference should be verified.
