How do I find the maximum watt rating for landscape lighting?
If you know the amperage and voltage of your landscape lighting you can use this to find the maximum watt rating. Simply use the formula Amps x Volts = Watts. Or you can head over to the ' Watt Calculator' to work this out. Let's take a look at specific examples of how many watts landscape lighting draws.
How do I measure watts & lumens in commercial solar lighting?
For commercial solar lighting applications, we recommend using Foot Candle (or Lux in the metric system) as the measurement to determine how illuminated a surface should be. For more on Watts, Lumens and Foot Candles in commercial solar lighting, see our Commercial Grade Solar Lights: Guide to Watts, Lumens and Foot Candles – Part 1 blog.
