Yes, eye protection is recommended as the LEDS are very bright - although the wavelengths used are themselves not considered dangerous.  If you do choose to use a red-light panel without using eye protection, then we recommend you do not stare directly into the LEDs.

The standard Dermfix RLF LED panels are not certified beyond an IP20 rating
which means they are not suitable for bathrooms, outdoors, saunas or
anywhere there is a risk of water or steam contact.  Suitable areas
inside the house are bedrooms, living rooms or similar. But we do also have our RLF SPA panels that are IP65 rated against water and humidity and these are suitable for damp and hot environments.

Absolutely.  Here at Dermfix we are aware of the benefits of some
sensible sunlight exposure (Vitamin D production etc) but red light does
not have UV-A and UV-B and therefore can be used in a safer and more
regulated manner than exposure to natural sunlight.  Like many things in
life, a little of both can be good.

The RLF units are fitted with dual LEDs so that the 7 wavelengths are
spread as evenly as possible across the LED panel.  Each LED is made of a
combination of 2 wavelengths and this leads to colour differences when
viewed with the human eye.

Ideally not.  Red light is blocked by clothing and most of the near-infrared is also blocked.  We recommend wearing as little clothing as possible  or ideally none at all! Clean dry skin is best and with no lotions or creams applied.

These simple and convenient buttons allow for a range of quick everyday
settings.  Exact details of the settings are included in the
instruction’s manuals included with the LED panels, showing the
different percentage of wavelengths and the times that are used for each
smart mode.  We think these are the quickest and easiest way to use the
devices once you have a chosen mode that suits your lifestyle and
needs.
