What sells, and why

These are the Dermfix devices UK customers buy most often. The pattern is fairly consistent: people buy the half-body panel when they want one device that covers most of what they need, the Halo when the face is the priority, and the 1000MX when a dermatologist has raised narrowband UVB.

Choosing between them

• RLF1500 — the all-rounder. 300 dual-chip LEDs, seven wavelengths, 89 mW/cm² measured at 15cm. Covers half the body per session, which suits most home routines without needing a dedicated room.
• Halo LED — the facial choice. Four wavelengths across 240 LEDs, contact-free, three brightness levels. Nothing sits on the skin, and it works on other areas too.
• RLF3000 — full-body standing sessions. 600 LEDs, 90 mW/cm² at 15cm. Shorter sessions because it covers more at once.
• Dermfix 1000MX — narrowband UVB 311nm, handheld, with interchangeable flat and comb lenses. A medical device for psoriasis, vitiligo and atopic eczema, and a different treatment entirely from red light.

Before you choose on popularity alone

Best-selling is a useful signal but a poor specification. The better questions are what area you want to treat, whether you want red light or narrowband UVB, and — if it is a panel — what measured output it publishes and at what distance.

Our UK buyer's guide works through those, including how irradiance figures get inflated and what competing panels actually cost once import VAT is accounted for. For narrowband UVB, our guide to UVB phototherapy explains how the wavelengths differ and why 311nm became the clinical standard.

Frequently asked questions

Which Dermfix panel is most popular?
The RLF1500 half-body panel, because it covers most of what home users want in one device without needing a dedicated space.

Should I buy a red light panel or a UVB lamp?
They treat different things. Red light panels emit no ultraviolet and are used for general wellbeing, skin appearance and recovery. Narrowband UVB 311nm lamps are medical devices used for psoriasis, vitiligo and atopic eczema. If you have a diagnosed condition, speak to your dermatologist.
