A Yes, they can be cut to desired lengths.

A In the middle of the LED SMD there is an N-type and a P-type semiconductor. The N-type has electrons and the P-type has holes. The holes and electrons rapidly cross the gap and then merge together. As they combine, it produces photons which in turn produces particles of light.

A A LED strip light is a flexible circuit board that is populated with LEDs. Strip lighting allows you to install powerful, energy efficient, discreet lighting fixtures in places you normally wouldn’t be able to reach.

A

A This is a rating system that defines the ability of a product to be able to work in different environments. IP is an acronym "Ingress Protection". It is a measurement of the protection an item will have against solid objects (dust, sand, dirt, etc.) and liquids.

A This is calculated by measuring the lumen output and then dividing that number by watts. For example, a strip that has a lumen output of 1200lm/meter and a wattage draw of 12w/m has an efficiency of 100lm/W.

A Simply put, binning is the process of grouping LEDs during production so that they matched with LEDs of the same color sector. For example, all 2700K chips are ‘binned’ together and are separated from chips that have a higher/lower color temperature.

A A watt is equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere. A watt is equal to the voltage multiplied by the amperage. This is how your electric company keeps track of how much energy you consume.
