Aisirer Bulb brightness

I have an Aisirer bulb set up for my bathroom. It should have different brightness values throughout the day/night. I did accomplish it but the 100% brightness seems off to what the bulb has when it is turned on.

Here is the esphome yml:

esphome:
  name: bad
  platform: ESP8266
  board: esp01_1m
  on_loop:
    then:
     - if:
        condition:
          or:
           - lambda: 'return id(homeassistant_time).now().hour > 21;'
           - lambda: 'return id(homeassistant_time).now().hour < 6;'
        then:
          - logger.log:
              format: "time1 %.0i"
              args: [ 'id(homeassistant_time).now().hour' ]
              level: WARN
          - light.control: 
              id: licht
              brightness: 0.14
          #- output.set_level:
          #    id: output_component1
          #    level: 0.5
        else:
          - logger.log:
              format: "time2: %.0i"
              args: [ 'id(homeassistant_time).now().hour' ]
              level: WARN
          - light.control: 
              id: licht
              brightness: 1
          #- output.set_level:
          #    id: output_component1
          #    level: 0.5

wifi:
  ssid: !secret wlan_ssid
  password: !secret wlan_password
  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Bad Fallback Hotspot"
    password: "..."

captive_portal:

# Enable logging
logger:
  level: ERROR

# Enable Home Assistant API
api:
  password: !secret generalpassword

ota:
  password: !secret generalpassword
  
time:
  - platform: homeassistant
    id: homeassistant_time
  
light:
  - platform: monochromatic
    name: "Bad"
    id: licht
    output: output_component1
    restore_mode: ALWAYS_ON
    gamma_correct: 0

output:
  - platform: esp8266_pwm
    id: output_component1
    pin: GPIO05

So when the bulb turns on via the switch it has full brightness. After the on_loop automation kicks in, the brightness becomes less although it shows 100% in home assistant. I played a bit with the gamma_correct value without success. What did I miss?
