Set up a colored lamp using its manual, check controls and glare, record measured illuminance and distinguish ambient lighting from clinical light therapy.
Write down the exact model, manual and purpose. For decorative lighting, identify whether it changes white appearance, saturated color, brightness or several of these. If you are seeking treatment for seasonal depression, use the seasonal mood guide to prepare a care discussion before choosing a treatment device.
Follow the product instructions for mounting, clearance, power supply and compatible dimming. Identify the off control and a comfortable ordinary-light setting. Test the light from the seats and work surfaces that people actually use, including reflections on screens.
Note the actual device controls and viewing position. If you have a meter reading or documented illuminance at a stated location, use Lux to Foot-Candles only to translate its units. Preserve the reading location, distance, orientation and measurement source.
Try the chosen setting while doing the actual activity. Check visibility, reflections and comfort; adjust or switch off if it is unpleasant. Save the preferred controls and a simple return-to-ordinary-light instruction for other users.

DOE distinguishes dim-to-warm, white-tunable and full-color-tunable products; their controls differ. HSE describes lighting as dependent on the task, including contrast and glare. Review the actual fixture and use rather than judging a room by a Kelvin value or swatch alone.
NIMH describes bright-light therapy as a treatment option for winter-pattern seasonal affective disorder using a purpose-specific light box. Eye conditions and medications that increase light sensitivity can affect suitability. Discuss the device, timing and supervision with a healthcare professional; decorative RGB settings do not establish an equivalent treatment.
Fill this record for the actual lamp and room. Leave measurement fields marked “not measured” when you have no reading.
| Record | Your note |
|---|---|
| Fixture and purpose | [model, manual, ambient/task use] |
| Controls and placement | [mode, dimmer, position and off control] |
| Illuminance if available | [reading and unit; source, location, distance, orientation] |
| Room review | [activity, daylight, glare and comfort observations] |
| Saved setting | [controls to repeat; ordinary-light fallback] |
Save the control values, location and time-of-day context. A screenshot of a color slider alone leaves out brightness, placement and daylight.
