Short answer: The best red light therapy panel for you is the one that combines the right wavelengths (660nm red + 850nm near-infrared as a minimum), honestly measured irradiance (aim for 40–100 mW/cm² at 15cm), a size that matches your treatment area, CE certification, and — if you're in the EU — EU stock so you avoid customs. Below is how to weigh each factor, plus how the Dermfix range fits.
What wavelengths do you actually need?
The most researched wavelengths are 660nm (red) for skin and surface tissue, and 850nm (near-infrared) for deeper tissue, muscles and joints. Extra wavelengths (480, 630, 810, 830, 1060nm) can add flexibility but are not essential if the basics are strong. As a rule: make sure the panel clearly lists its wavelengths in nanometres — vague “red LED” claims are a red flag. The Dermfix RLF range uses 7 selectable wavelengths (480, 630, 660, 810, 830, 850, 1060nm), so you can target skin and deep tissue from one device.
How much power (irradiance) is enough?
Irradiance — measured in mW/cm² — is how much light energy reaches your skin. More isn't always better; it mainly shortens session time. For home use, a realistic 40–100 mW/cm² at 15cm is effective. The key is an honest, measured figure at a stated distance, ideally verified with a spectrometer — many brands inflate this number. Every Dermfix RLF panel publishes its independently spectrometer-tested output — 82 mW/cm² (RLF750) up to 92 mW/cm² (RLF6000) at 15cm.
What size panel should you buy?
Match the panel to your treatment area:
- Face / small areas: a compact panel (e.g. Dermfix RLF750) or a face-and-body LED panel (Dermfix Halo).
- Half-body: a mid-size panel (Dermfix RLF1500).
- Full-body: a large panel (Dermfix RLF3000 or RLF6000). Bigger panels cover more at once, so sessions are shorter.
What about EMF, flicker and safety?
For daily use, prefer panels that are low-EMF and flicker-free, and always look for genuine CE certification — specifically EN 60335-2-27, the correct standard for skin exposure to optical radiation above 780nm. Use eye protection or avoid staring directly into the LEDs.
Buying in the EU: customs, warranty and support
A US or UK panel can land with unexpected VAT/customs charges and slower support. An EU-based supplier with EU stock avoids customs for EU buyers and makes returns and warranty simpler. Look for at least a 2-year warranty (3 years is better). Dermfix is an EU manufacturer (Austria) shipping from EU stock, with a 3-year warranty and local country stores across around 20 EU markets.

All RLF panels: 7 wavelengths (480–1060nm), CE-tested (EN 60335-2-27), 3-year warranty, EU stock.
Frequently asked questions
Is red light therapy the same as UVB?
No. Red/near-infrared light supports skin, recovery and wellbeing with no UV. UVB narrowband (311nm) is a separate, targeted phototherapy for conditions like psoriasis and vitiligo. Dermfix makes both.
How often should I use a red light panel?
Most home protocols are short daily or every-other-day sessions (roughly 5–20 minutes) at 15–30cm. Follow your device's manual and adjust to your routine.
Do I need multiple wavelengths?
660nm + 850nm covers most needs. Extra wavelengths add flexibility but aren't essential if irradiance and build quality are good.
Red light panel or mat — which is better?
Panels are more powerful and better for the face, targeted areas and standing full-body sessions. Mats wrap around the body for hands-free, lie-down treatment. Dermfix offers both.
