We're excited to announce the best calculator yet. It does the following: Calculates voltage loss and energy consumption for any combination of LED and/or incandescent fixtures. Automatically calculates VA's for LED's. Accomodates Daisy Chain, T-Method, Spider Splice or combination of all three. Can accommodate up to 30 fixtures on a daisy chain; 60 fixtures on a T-Method; and unlimited number with Spider Splice combinations. Automatically populates data for CAST fixtures and transformers and allows you to enter other mfg. products. Warns you when wire amperage is too high; and when fixture voltages fall outside acceptable ranges. Feedback and comments welcome. Download page for new calculator.
