It’s a unit of measurement used to describe the wavelength of light emitted by the LED devices. Intensity
Brightness/
DimmingIn LED light therapy, intensity, brightness, and dimming are all related to the amount of light energy emitted by the device, how it affects the treatment and the ability to adjust the intensity (and therefore the brightness) of the LED light. Pulse/Hz Pulse/Hz In LED light therapy, Hz: Hertz is a unit of frequency, pulse/Hz (Hertz) refers to the frequency at which the LED light turns on and off in a rhythmic pattern per second. For example, a pulse frequency of 10 Hz means the light pulses 10 times per second. LEDs / Lens Light Emitting Diode LED is a semiconductor device that emits light when an electric current passes through it. “lens angle” refers to how wide the beam of light spreads out from the LED device.
Wide (60-90 degrees): suitable for larger areas like back and chest. Medium (30-60 degrees): areas like the face or joints. Narrow (10-30 degrees): specific points or smaller areas of concern.Irradiance
/ mWmilliwatts per centimetre square Irradiance (mW/cm²) refers to the power density of the LED light, or how much light energy (in milliwatts) is delivered to a specific area of skin (one centimetre square). Different conditions and skin types require different levels of irradiance.
It’s essential to use a device that delivers the appropriate mW/cm² for your specific needs and to follow the manufacturer’s recommended treatment times.EMF µT Electromagnetic Field In the context of LED light therapy, EMF µT refers to the strength of the electromagnetic field (EMF) emitted by the device, measured in microteslas (µT) - Delivery & Return

Description
LED Light Therapy Irradiance Tester: Device Measurement at an Affordable Price
The TES-1333 Solar Power Meter is a popular choice for anyone who needs a practical way to measure light intensity—whether for Blue, Green, Yellow, Red, or Near-Infrared light therapy, this handheld device is ready to measure your products light intensity with ease.
✅ In summary: The TES-1333 isn’t a laboratory-grade device, but for under £125, it gives you reliable, practical, and consistent readings across the visible and NIR spectrum—perfect for anyone who wants to better understand their light environment without breaking the bank.
Why It’s Useful for Light Therapy Users
- Check Your LED Light Therapy Output – Make sure your LED therapy panels, wearables, etc delivers within the recommended ranges for skin and wellness treatments.
- Compare Devices – Test different panels, lamps, or bulbs at home to see which delivers the best value.
- Track Consistency – Ensure your light source hasn’t weakened over time.
TES 1333 also can measure solar setups, plant growth, or environmental monitoring. With a wide spectral response of 400–1100 nm and 0–2000 W/m² measurement range, which is simple to convert into mW/cm²:
✅ Example Conversions
- Reading of 100 W/m² = 10 mW/cm²
- Reading of 500 W/m² = 50 mW/cm²
- Reading of 1000 W/m² = 100 mW/cm²
🧠 Practical Tip
Since it’s easy to forget the conversion, you can:
- Write the formula on a sticky note and keep it in your TES-1333 case.
A versatile tool that offers great value under £125.
Unlike Class A laboratory meters that cost thousands, the TES-1333 provides good everyday accuracy (±5% or ±10 W/m²), making it ideal for users who simply want to check if their devices are delivering consistent and effective levels of light.
Who Uses the TES-1333?
- Households: For light therapy, home solar checks, and even gardening.
- Professionals: Physiotherapists, estheticians, and wellness clinics use it to validate equipment output.
- Solar Installers & Architects: For testing window transmittance and sun exposure.
- Researchers & Hobbyists: For experiments that need general but reliable irradiance data.
Why Choose TES-1333 Over Expensive Meters?
If you need absolute scientific precision, you’ll want a Class A certified Spectrometer (costing £500+). But for most light therapy enthusiasts, households, and small businesses, the TES-1333 offers reliable, consistent readings at a fraction of the price—making it one of the best entry-level tools for everyday light testing.
