WebEnergy Cost of Lighting Daily = Total Watts * Hours On per Day * Energy Cost ($/kWhr) NOTE: For Dusk to Dawn, use 12 hours; and we take the average $0.12/KWHr in the US in the calculation. Typical Halogen Bulb Cost Daily= 40W * 12H * $0.12/KWHr = $57.6. LOHAS LED Dusk to Dawn Bulb Cost Daily= 6W * 12H * $0.12/KWHr = $ 8.64. WebApr 3, 2024 · $$ R = \frac{3.0 - 1.8}{0.02}= 60$$ You need at least a 60 ohm resistor to safely operate a red LED from 2 AA cells in series. It'll probably be far too bright, though. You can safely use larger value resistors to dim a bright LED. You'll probably have to try it out and see how high you need to make the resistor to dim the LED to your liking.
