A panel and a bed deliver the same thing — red and near-infrared light at a dose. What differs is coverage, session time, consistency, and how much space and money you are prepared to commit.
Panels
A panel treats the area in front of it. To cover your whole body you either use a large panel and turn around, or treat areas in sequence — which turns one session into several. Panels are far cheaper, can be wall-mounted or put on a stand, and can be moved.
The variable a panel introduces is distance. You stand where you stand, and irradiance falls off sharply with distance, so the dose varies between sessions unless you are deliberate about it.
Beds
A bed surrounds you, delivering whole-body coverage in a single session at a consistent, fixed distance. Session times are shorter and the dose is far more repeatable. The cost is substantially higher and the footprint is a permanent commitment — a bed is furniture you plan a room around.
Which to buy
- Treating one or two specific areas: a targeted or half-body panel is sufficient and much cheaper.
- Whole-body use at home, with patience for turning around: a large panel is usually the sensible choice.
- Whole-body use where session time and consistency matter, or several users daily: a bed.
- Commercial settings — studios, med spas, gyms: a bed almost always, because it standardises distance and cuts turnaround.
The specification that decides both
Irradiance at a stated distance, and the resulting dose per session. Total wattage and LED count describe what the device draws and how many diodes it has, not what reaches you. Research on photobiomodulation describes a biphasic dose response — more is not linearly better, and past a point additional output can produce less effect — which is precisely why a manufacturer who cannot state dose is not giving you a comparable product.
Space
For a panel, the real space requirement is the clear floor area at the manufacturer’s stated treatment distance, not the panel footprint. For a bed, it is the bed plus access along one long side.
