Frequently Asked Questions
Q: What are “watts”?
A: A watt is the unit of measurement for the amount of electricity a light fixture uses. When you’re talking about incandescent light bulbs, this term is commonly also used to express brightness, even though watts don’t tell you anything about how bright a light is. “Lumens” is the measure of brightness. With our LED lights, the wattage always means simply how much power is used. A typical 40W light bulb draws 40 watts of power and gives off about 300 lumens of brightness, while an LED bulb of 300 lumens might use about 6 watts.
Q: What is “voltage drop”?
A: “Voltage drop” means the gradual diminishing of voltage along the length of the wire as electricity travels away from a power source. The term applies to what happens when a light or appliance is at a great distance from the power source.
Q: What is an “IP rating”?
A: “IP” stands for Ingress Protection. All of our products have IP ratings, which always has two numbers: the first stands for the protection against solid objects, the second number for protection against liquid. The highest IP rating is 68, and it tells you that the protection against solid objects is a 6, and the protection against liquid is an 8. Click here to see a PDF of the IP Rating scale.
Q: What are “lumens”?
A: “Lumens” is the unit of measurement for the brightness of a light. Don’t confuse this with “wattage”, which is the unit of measurement for the electricity consumed by a light.
Q: What is “color temperature”?
A: The color temperature of a light fixture is a measurement of the amount of yellow or blue in the white light that it produces. This measurement is expressed in kelvins; a higher kelvin number means the light is cooler/more blue, and a lower number means that it’s warmer/more yellow.
