LED Lights Energy Savings Breakeven Calculator
(worst-case scenario)

Instructions: Enter your own data in the yellow cells. Your savings shows in green. Your unadjusted breakeven point shows in blue. The gray boxes are filled in automatically for your convenience. Do not change the figures in the gray boxes. You may widen the columns if the titles are not fully visible. Place your mouse on the vertical line between two letters (e.g. point to the line between columns C and D). When it becomes a double arrow, click and hold while moving mouse to the right. This will widen the column on the left and not affect the column on the right.

Watts, Volts & Amps Calculator: Choose one of the three calculators below. Fill in the two yellow blanks in that row based on the information you know about the products you wish to compare. The gray box represents your unknown factor. Do not fill in the gray box.

NOTE: If the item you want to compare does not list Watts on its label, calculating Watts is easy with our calculator in the red box. Use the formula Watts = Volts x Amps. For instance, if a product label states "120v, 1.5 amps" you would multiply 120 x 1.5 to get 180 Watts.

Important: For accuracy, you need to adjust your breakeven point with the following factors: Cost of replacement bulbs (LED bulbs will outlast regular bulbs up to 30-fold), labor and risk of injury while replacing burned-out bulbs (one LED bulb will outlive up to 30 other bulbs), risk of fire (LED bulbs burn cool to the touch), cost of air conditioning (LED bulbs burn cool and won't greatly impact indoor environment with wasted heat), and replacement due to beam angle changes (each of our LED spot lamps has variable beam angle).
