Cold White + Warm White Light
=============================

:description: Instructions for setting up Cold White + Warm White lights.
:image: brightness-medium.png
The ``cwww`` light platform creates an Cold-White+Warm-White
light from 2 :ref:`float output components <output>` (one for each channel). The two
channels will be mixed using the color temperature configuration options.
.. code-block:: yaml
# Example configuration entry
light:
- platform: cwww
name: "Livingroom Lights"
cold_white: output_component1
warm_white: output_component2
cold_white_color_temperature: 153 mireds
warm_white_color_temperature: 500 mireds
Configuration variables:
------------------------
- **name** (**Required**, string): The name of the light.
- **cold_white** (**Required**, :ref:`config-id`): The id of the float :ref:`output` to use for the cold white channel.
- **warm_white** (**Required**, :ref:`config-id`): The id of the float :ref:`output` to use for the warm white channel.
- **cold_white_color_temperature** (**Required**, float): The color temperate (in `mireds <https://en.wikipedia.org/wiki/Mired>`__)
of the cold white channel.
- **warm_white_color_temperature** (**Required**, float): The color temperate (in `mireds <https://en.wikipedia.org/wiki/Mired>`__)
of the warm white channel.
- **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 CWWW 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`.
