The Dermfix SLF1800 is a new size in our range. It sits between our RLF1500 and RLF3000, for customers who want something in between: the full 42 cm width of the RLF3000 at 91 cm tall. As we were developing a new panel size anyway, we took the opportunity to add a few extra features, such as a touchscreen in 14 languages and ready-made programmes.
Features
- Seven wavelengths. 460–480 nm blue, 630 nm and 660 nm red, and 810, 830, 850 and 1060 nm near-infrared, across 360 × 5 W dual-chip LEDs.
- Every wavelength dimmable on its own. Set each one anywhere from 0 to 100%. Run red only, near-infrared only, or build your own blend.
- Measured output. 83.3 mW/cm² initial output and 74.0 mW/cm² sustained output (after 10 minutes) at 15 cm, measured by LightingLab, an independent ISO/IEC 17025-accredited laboratory (certificate LL-26-6174). How we measured it, and why panel figures differ.
- Our own operating system and remote. Designed by Dermfix. The touchscreen and the handheld remote give the same functions, and the touchscreen runs in fourteen languages.
- One-press programmes. Six presets (Post-workout, Anti-aging, Joint Pain, Skin, Wake-up, Warm-up) plus two of your own saved setups.
- Timer from 1 to 30 minutes. The panel switches off when your session ends.
- Flicker-free LEDs, 30° beam angle, 8 cooling fans and a 50,000-hour LED lifespan.
- Easy to place. At 12 kg it hangs on a door hook (included) or sits on one of our optional stands in a spare room.

Who should choose the SLF1800? If the RLF1500 feels a little small but you don't need the size of the RLF3000, the SLF1800 is the panel for you. In one position it covers the torso, the back or a full leg; standing sessions are done front then back.

Frequently asked questions
Can I use only red light, or only near-infrared?
Yes. Each of the seven wavelengths can be dimmed from 0 to 100% on its own, so you can switch any of them off completely. Most users work with red and near-infrared together; the blue channel is separate and is not needed for a standard session.
How do I mount it?
A door hook and adjustable hanging cables are included. For freestanding use, choose the Manual Floor Stand for horizontal or vertical positioning, or the lightweight Base Stand on castors.
