Salt has three lighting scenes that have different battery runtimes due to the different levels of red.
You can find out how long Salt lasts at maximum brightness in each lighting scene here.
If you operate Salt in Clear Light mode at the lowest dimming level, Salt will light up for well over 500 hours.
Experience has shown that the average battery life of 150 hours specified by us is only achieved when dimming to well below 50% brightness in Clear Light mode.
