Whether you choose to order a custom length strip, or make in-field length modifications, precise strip measurements are critical in the overall performance and appearance of the LED light source.
Linear LED strips can come in reels anywhere from 16' to 1000' in length and can modified in-field by hand to the desired length using standard scissors along the indicated cut lines or solder points. These marked cut lines are what's known as "cut points".
In the manufacturing process, LED diodes are mounted on a substrate that house the electronics (diodes) and power (resistors). On the underside, a double face tape is adhered to the back of the substrate for ease of mounting - thus the common name of "tape" for the product.
Cut points vary among manufacturers from anywhere between 1" to 6" or more. Every cut point adds complexity and cost in the manufacturing process. This is why some manufacturers will choose to spread them out to minimize production costs in order to offer lower-priced products. So what does this all mean, exactly?
The Shorter the Cut Point, The More Uniform The Light
The cut points are an important factor in a linear LED fixtures performance when installed. When an application does not have perfect measurements designed around the specific cut point, this leads to large dark ends on certain runs.
