So graphs and pie-charts are good on paper but real world isn’t the same. We are off grid up here in N Idaho. I have 2 LT1s and love them to death. One hangs in the livingroom and one in the bathroom. We use them every morning and every night. Time is aprox 4-5hrs per day. We get about 5 days use before they start auto-dimming levels (means it needs charging). The one in the bathroom will go almost 7 days because we use it on a lower mode, but we charge both at same time.

So 5-7 days of real world use. If you were frugal and used at lowest setting that you could see by it might last 2 weeks.
