Monochromatic Light
===================

:description: Instructions for setting up monochromatic (brightness-only) lights.
:image: brightness-medium.png
The ``monochromatic`` light platform creates a simple brightness-only light from an
:ref:`float output component <output>`.

Example of a brightness-only LED strip that can be used with this component.

# Example configuration entry
light:
- platform: monochromatic
name: "Kitchen Lights"
output: output_component1
Configuration variables:
------------------------
- **name** (**Required**, string): The name of the light.
- **output** (**Required**, :ref:`config-id`): The id of the float :ref:`output` to use for this light.
- **gamma_correct** (*Optional*, float): The `gamma correction
factor <https://en.wikipedia.org/wiki/Gamma_correction>`__ for the light. Defaults to ``2.8``.
- **default_transition_length** (*Optional*, :ref:`config-time`): The length of
the transition if no transition parameter is provided by Home
Assistant. Defaults to ``1s``.
- **effects** (*Optional*, list): A list of :ref:`light effects <light-effects>` to use for this light.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
- All other options from :ref:`MQTT Component <config-mqtt-component>`.
.. note::
The ``monochromatic`` light platform only works with ``float``
:ref:`outputs <output>` that can output any light intensity percentage like the
:doc:`ESP32 LEDC </components/output/ledc>` or
:doc:`ESP8266 PWM </components/output/esp8266_pwm>` components and does **not** work with output
platforms like the :doc:`/components/output/gpio`.
