150 W Samsung light consumption
At full power for 16 hours a day: 150 W × 16 hours = 2.4 kWh/day, or 72 kWh over 30 days for the light alone.
The four fans and other components add to this figure. Measure total consumption with a plug-in energy meter, then multiply the measured kWh by the unit rate on your electricity bill to estimate cost. Actual consumption depends on operating settings.
