The MedLight M4 and M4+ are full-body red light therapy tanning beds designed for wellness centers, recovery studios, gyms, beauty salons and other professional facilities.
The familiar bed-style design provides broad exposure from above and below the body. Unlike a traditional tanning bed, the M4 series does not use ultraviolet light. It uses red and near-infrared LEDs to support muscle recovery, joint comfort, circulation and general skin wellness.
M4 and M4+ share the same compact body size and control functions. The main differences are LED quantity, power and electrical current. This gives buyers two practical options for different budgets, service volumes and performance requirements.
Description and Benefits
Full-body coverage in one session
The surrounding LED layout exposes large areas of the body at the same time. Clients do not need to turn around or reposition a small panel during the session.
This makes the M4 series suitable for businesses that want a straightforward full-body service with predictable appointment times. A typical session lasts 10–20 minutes, helping operators plan bookings and room usage more efficiently.
Red and near-infrared wavelengths
The M4 series uses 633 nm and 660 nm red light together with 850 nm and 940 nm near-infrared light.
Red light is mainly used for surface-level skin exposure, while near-infrared light penetrates more deeply and is commonly selected for muscle and joint recovery routines. Each wavelength can be controlled independently, allowing the operator to create different protocols for different services.
The final wavelength configuration should be confirmed before production, especially for customized orders.
M4 and M4+ options
The M4 is equipped with 11,616 LEDs and has a rated power of 1,160 W. It is the more economical option for facilities introducing full-body red light therapy or expecting moderate daily use.
The M4+ increases the LED quantity to 28,512 and the rated power to 2,850 W. It is more suitable for commercial operators who want a higher-output configuration or expect a heavier appointment schedule.
| Model | LED Quantity | Current at 220 V | Rated Power |
|---|---|---|---|
| M4 | 11,616 pcs | 6 A | 1,160 W |
| M4+ | 28,512 pcs | 13 A | 2,850 W |
LED quantity and power are not the only factors that affect treatment performance. Irradiance, treatment distance, wavelength selection, session time and protocol settings should also be considered.
Adjustable pulse and wavelength control
The pulse system can be adjusted from continuous output to frequencies up to 1,000 Hz. Operators can select wavelengths and configure pulse frequency and duty cycle through the controller.
The system also provides preset protocols and a manual mode. This makes daily operation easier for staff while still allowing experienced operators to create their own settings.
When the duty cycle is set to 100%, the light operates in continuous-wave mode. Lower duty-cycle settings create pulsed output.
Smart operation for commercial facilities
The M4 and M4+ can be configured with Smart Controller 2.0 or an optional Wireless Pad Controller 2.0. The control system supports:
- Independent wavelength selection
- Adjustable session time
- Preset and manual protocols
- Pulse frequency and duty-cycle settings
- Usage records
- Temperature monitoring
- Cooling-fan settings
- Wi-Fi and IoT management
- Bluetooth music control
The built-in Bluetooth stereo system allows clients to listen to music during a session. This is particularly useful for spas, wellness centers and recovery studios where the overall client experience matters.
Cooling and temperature protection
A full-body red light therapy tanning bed generates heat during operation, especially when used repeatedly throughout the day. The M4 series uses a forced-air cooling system to manage internal temperature and improve user comfort.
Operators can adjust the body-cooling fan from level 1 to level 3. The system also allows the facility to set:
- Cooling-fan startup temperature
- Overheat warning temperature
- Fan delay after each session
- Current internal temperature monitoring
If the internal temperature reaches the selected warning point, the system displays an overheat message. Proper ventilation around the machine is still required.
Compact footprint for a full-body bed
The M4 series measures 1935 × 855 × 990 mm when closed. Its open height is approximately 1390 mm, while the internal width and height are 710 mm and 370 mm.
Compared with larger commercial beds, this relatively compact footprint makes room planning easier. Buyers should still leave enough space around the machine for opening, ventilation, cleaning and maintenance.
Simple session preparation
For better light exposure, the treatment area should be uncovered. Cosmetics, jewellery and other accessories should be removed where practical. Protective eyewear is included and should be worn during operation.
A common routine is 10–20 minutes per session, 3–5 times per week. The final session plan should be based on the facility’s service protocol and the individual user’s condition and tolerance.
The M4 and M4+ are wellness products and should not replace professional medical advice or treatment.
