Whether you are customizing the length of an LED strip or making in-field modifications, precision is crucial to achieve optimal performance and aesthetics. Linear LED strips are available in reels ranging from 16' to 1000' in length and can be easily cut to the desired length using standard scissors along the indicated cut lines or solder points. These designated cut lines are known as "cut points."

In the manufacturing process, LED diodes are mounted on a substrate that houses the electronics and power components. On the underside, a double-faced tape is adhered to the back of the substrate for easy mounting, leading to the common name "tape" for this product.

Cut points can vary among manufacturers, typically ranging from 1" to 6" or even more. Each cut point adds complexity and cost to the manufacturing process. Consequently, some manufacturers choose to minimize production costs by spacing out cut points, offering lower-priced products. But why do cut points matter? Let's explore further.

The Shorter the Cut Point, The More Uniform The Light

Cut points play a significant role in the performance of linear LED fixtures when installed. If an application does not align perfectly with the specific cut point measurements, it can result in large dark areas at the ends of the strip.

For instance, a 4' 3" run with a 4" cut point will have approximately 1.5" of darkness at each end. Even if the cut point was 6", the dark space would remain the same. However, a 2" cut point would reduce the dark space to just ½" per end, and a 1" cut point would provide full and even illumination across the entire application.

1" LED Cut Points Minimize Dark Spots

Linear LED lighting finds popular application in kitchen cabinetry, including in, above, under cabinet, and toe kick lighting. With various standard cabinet sizes and custom-built cabinets filling specific spaces, the measurements inside the cabinets can differ from those of the upper and under cabinets.

Although a dark space of 1.5" may seem insignificant, it can become highly visible depending on the application. If the under cabinet lighting is installed directly above a highly reflective countertop, the dark spaces become noticeable as you look at the countertop. The same concept applies when uplighting a bright ceiling above the cabinets. The smaller the dark space, the more uniform the lighting will appear between cabinets of different sizes. These principles apply not only to kitchen cabinets but also to other linear applications such as cove lighting, linear recessed lighting, linear surface lighting, millwork lighting, and perimeter lighting.

The shorter the cut point, the more uniform the light will appear regardless of the overall length. A 1" cut point limits the dark space to ½" or less, while a 2" cut point limits the dark space to less than 1". Cut points above 2" can result in dark spaces of 1.5" or more.

By understanding the importance of cut points and their impact on uniform illumination, you can make informed decisions when selecting LED strips for various applications.

Frequently Asked Questions

Q: Can I only use standard scissors to cut LED strips at the indicated cut lines?

A: Yes, standard scissors are typically sufficient to cut LED strips at the indicated cut lines. However, it's important to exercise caution and ensure a clean and precise cut.

Q: Are there any alternatives to cutting LED strips manually?

A: Yes, there are other options available for cutting LED strips, such as using a sharp utility knife or specialized LED strip cutting tools. These tools can provide even more precise cuts, especially for intricate installations.

Q: Can I connect multiple LED strips together after cutting them at the designated cut points?

A: Yes, it is possible to connect multiple LED strips together after cutting them at the designated cut points. However, ensure that you follow the manufacturer's instructions for proper wiring and connections to maintain optimal performance.

Q: Do all LED strips have the same cut point measurements?

A: No, cut point measurements can vary among manufacturers. It's essential to check the specifications provided by the manufacturer to ensure the compatibility of cut points with your specific application.

Q: Can I modify the cut point measurements of LED strips?

A: No, the cut point measurements are predetermined during the manufacturing process and cannot be modified. It's crucial to select LED strips with cut point measurements that align with your desired application.

Remember, when it comes to LED strips, precise measurements at cut points can significantly impact the overall performance and appearance of your lighting installation.
