Flowlight Bulb is easy to use and fits all lamp sockets with an E27 fitting. You can either install it directly into a ceiling lamp or use the included cable if you want to place the bulb closer to you during treatment.
If the bulb is installed in a regular lamp fixture, it is controlled using the standard wall switch connected to the outlet. If you use the included cable, simply plug it into a power outlet to start the bulb.
For most users, one bulb is enough for personal use. Additional bulbs are only recommended if you want to use them in multiple rooms or cover a larger area.
The Bulb still provides a effect even if you are positioned further away from the light. The main difference is that you may need a longer session to achieve the same exposure. The further away you are the longer the session.
