What is the optimal intensity for rgb in led?

[Jonnyboyyyy]

I ran test_led.py then test_image.py. It seems like the light intensity is too high.
In test_led.py, it is set to 255 for rgb channels.

led_all_off(Digit360(descriptor.data))
led_set_channel(Digit360(descriptor.data), d360frame.LightingChannel.CHANNEL_1, (255, 0, 0))
led_set_channel(Digit360(descriptor.data), d360frame.LightingChannel.CHANNEL_2, (0, 255, 0))
led_set_channel(Digit360(descriptor.data), d360frame.LightingChannel.CHANNEL_3, (0, 0, 255))

255 seems too bright to capture any useful data. What is the intensity used in Digit360 paper?

Below is the image obtained by setting 255 for RGB.
