Two distinct lensed options
Evo-Lite offers two distinct lensed lighting products, and each has its advantages. Depending on your application, these tools can deliver excellent results at a reduced cost.
The Auragami Basic Light Sheet with Lens delivers 850 lumens per square foot, and the 12" by 24" size is field-cuttable with easy plug-in connections. The TRAX Single Color with Lens Array produces around 400 lumens per square foot, measures 24" by 96" and offers excellent field-shaping abilities with snap-to-width LED bars and cut-to-length functionality.
The advantages of lensed LEDs
Adding a lens on these products helps accomplish a few things. The main benefit of adding a lens is the light distribution. The design of the lens spreads the light out, with each LED achieving a 175° beam angle.
This blends the light more quickly, producing even illumination in less space. An advantage like this allows us to reduce the number of LEDs on the product, helping to reduce its cost without affecting its performance.
Additionally, lensed products are easy to clean and the lenses provide an added layer of protection.
Limitations
While these lighting products will deliver outstanding results in many applications, there are a few limitations. The most notable thing to understand is that lensed products should only be used on flat surfaces.
The lenses need to be uniformly flat for the beam angles to homogenize correctly. Curves in the presentation cause the beam angles to fall out of alignment, potentially producing adverse color effects and bright/dark spots.
Another limitation is that lenses are only available for single-color products. Single-color products use a single white LED, allowing the lens to distribute the light in every direction evenly. Our tunable white products use two LEDs (warm white + cool white), and our RGBW products use four LEDs (red, green, blue, white).
With multiple LEDs, the lens can't be centered over each light source. For example, a tunable white LED group with a lens over it would produce warm white on one side and cool white on the other side, creating a separating effect instead of a blending effect.
While the lenses help blend the light, making up for the greater LED spacing, it's essential to test your forward facing material. As with every backlighting project, the key to even illumination is balancing the inherent, spatial, and physical diffusion.

Applications
Auragami Basic with Lens is great for any size project. The light sheet offers cutting increments down to a single LED, making it easy to fit your application. You can cover up to 10 square feet in a single 24VDC Class 2 circuit. Light sheets are installed using the adhesive backing and/or mechanical fasteners.
TRAX Lensed Arrays are more suited for medium to large project as each array covers 16 square feet. It can be shaped by snapping the LED bars to-size and/or cutting the array wires to length. These characteristics make it quite capable when needing to fit into oddly shaped spaces or navigating around obstacles. Lensed Arrays are fastened to the mounting surface using the built-in mounting clips or the time-saving rail mounting kit (sold separately).
