LG OLED55C5
The LG OLED55C5's certified consumption is 228 kWh per year, which prices out to about $42 at the national average rate — your hours of use scale that directly. Efficiency-wise it's unremarkable in a good way: within 22% of the median certified television (rank 119 of 180). The same unit costs $30 a year in Nevada but $120 in Hawaii — electricity rates, not the appliance, make the difference. Note the certified pool here is small (180 models), so rankings shift more with each data refresh.
