Red Light Devices for Hands and Wrists: Torch and Panel Placement
Quick answer: Hands and wrists are small targets, so a torch or a panel at a measured distance both work. Rest your arm on a table, hold the distance from the manual and use a timer so each session is consistent.
Hands are easy to expose to light because you can rest them in front of a device. This guide covers placement, with no health claims.
Two simple setups
| Setup | How it works | Good to know |
|---|---|---|
| Torch | Hold or prop the torch at the manual's distance | Portable, small area |
| Panel | Rest your hands in front of the panel | Hands free once set |
Placement steps
- Sit at a table with your forearm supported.
- Place the device at the distance in the manual.
- Keep the beam pointed away from your eyes.
- Run the timer, then switch off.
Distance changes intensity. See the irradiance specs for measured values on the panels.
Common mistakes
- Holding the torch in a shaky position and changing distance.
- Using a long session because the device feels gentle.
- Wearing jewelry that may reflect light toward your face.
