It is 42 cm wide, the same as the RLF3000, but only 91 cm tall, so one session covers the upper body, the back or a whole leg. If you stand for your sessions, do the front first and then turn round for the back. At 12 kg it hangs from a door using the supplied hook, or sits on one of the optional stands, so a bedroom or home office is all the space you need.\u003c\/p\u003e\n\n\u003ch2\u003eIndependent laboratory result\u003c\/h2\u003e\n\u003cp\u003eIn November 2026 the SLF1800 was tested by LightingLab Calibration Laboratory Ltd. in Veszprém, Hungary. It measured \u003cstrong\u003e83.3 mW\/cm² at a distance of 15 cm\u003c\/strong\u003e and 73.8 mW\/cm² at 30 cm. LightingLab is an ISO\/IEC 17025-accredited calibration laboratory that works independently of us, and the readings were taken with a calibrated spectroradiometer.\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eDistance\u003c\/th\u003e\n\u003cth\u003eTotal irradiance, all 7 wavelengths on\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e15 cm\u003c\/td\u003e\n\u003ctd\u003e83.3 mW\/cm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e30 cm\u003c\/td\u003e\n\u003ctd\u003e73.8 mW\/cm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eTwice the distance, 89% of the output.\u003c\/strong\u003e The 30° lenses hold the light in a forward-facing beam rather than letting it fan out to the sides, so the reading barely falls between 15 and 30 cm. Sitting further back puts more of your body in the light at once, and you still receive close to 90% of the close-range dose. For real-world use, we think that matters more than any single peak figure.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eTest conditions:\u003c\/em\u003e total irradiance from 200 to 1100 nm, all wavelengths at 100%, sensor at the centre of the panel, distance measured from the front face, reading taken immediately after switch-on with no warm-up time.\u003c\/p\u003e\n\n\u003ch2\u003eSeven wavelengths\u003c\/h2\u003e\n\u003cp\u003eThe panel carries 360 dual-chip LEDs across seven wavelengths, and every channel has its own 0–100% dimmer.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e460–480 nm, blue:\u003c\/strong\u003e visible light, absorbed at the skin surface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e630 nm, red:\u003c\/strong\u003e visible, absorbed in the epidermis and upper dermis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e660 nm, red:\u003c\/strong\u003e visible, reaches slightly deeper than 630 nm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e810 nm, near-infrared:\u003c\/strong\u003e invisible, passes beyond the dermis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e830 nm, near-infrared:\u003c\/strong\u003e invisible.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e850 nm, near-infrared:\u003c\/strong\u003e invisible, the most extensively studied NIR wavelength.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1060 nm, near-infrared:\u003c\/strong\u003e invisible, the longest wavelength in our range.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUse the wavelengths on their own or together.

Everything on the panel's touchscreen can also be done from the handheld remote: dimming each wavelength from 0 to 100%, pulsing from 0 to 9999 Hz across all wavelengths together, and a 1–30 minute timer that switches the panel off when the session ends.\u003c\/p\u003e\n\u003cp\u003eOne button press on the remote starts any of six built-in programmes (Post-workout, Anti-aging, Joint Pain, Skin, Wake-up, Warm-up) or either of two programmes you save yourself, so a routine session needs no menus at all.\u003c\/p\u003e\n\u003cp\u003eThe touchscreen speaks fourteen languages, which suits a panel built for customers across Europe. The LEDs do not flicker, which is useful if you film in the same room or are sensitive to modulated light.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLEDs\u003c\/td\u003e\n\u003ctd\u003e360 dual-chip, 5 W each\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWavelengths\u003c\/td\u003e\n\u003ctd\u003e460–480, 630, 660, 810, 830, 850, 1060 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasured irradiance\u003c\/td\u003e\n\u003ctd\u003e83.3 mW\/cm² at 15 cm, 73.8 mW\/cm² at 30 cm (LightingLab, independent lab test, November 2026)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam angle\u003c\/td\u003e\n\u003ctd\u003e30°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower draw\u003c\/td\u003e\n\u003ctd\u003e670 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMains supply\u003c\/td\u003e\n\u003ctd\u003e100–240 V AC, 50\/60 Hz, supplied with an EU plug (Swiss plug on request)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003e91 × 42 × 6.5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoverage\u003c\/td\u003e\n\u003ctd\u003eHalf body, 42 cm wide like the RLF3000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e12 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCooling\u003c\/td\u003e\n\u003ctd\u003e8 fans\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProgrammes\u003c\/td\u003e\n\u003ctd\u003e6 built-in, 2 user memories\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated LED life\u003c\/td\u003e\n\u003ctd\u003e50,000 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTimer\u003c\/td\u003e\n\u003ctd\u003e1 to 30 minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePulsing\u003c\/td\u003e\n\u003ctd\u003e0–9999 Hz, all wavelengths together\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTouchscreen languages\u003c\/td\u003e\n\u003ctd\u003e14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHousing\u003c\/td\u003e\n\u003ctd\u003eMetal, IP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhotobiological safety\u003c\/td\u003e\n\u003ctd\u003eRisk Group 2 under IEC 62471.
