The Radion diffuser utilizes an engineered diffuser material with an optimized airspace, the result is enhanced color mixing and more uniform caustics. Working with the existing optics equipped on the Radion fixtures, a diffuser offers a more pleasing light appearance with only a marginal reduction in PAR.Upgrade your Ecotech Marine Radion XR30 Light! Increased blending Decreased shadows Decreased color separation Installs in minutes Compatible with all XR15 Gen 3 and Gen 4 Lights Even Spread & ColorationOnce you put the XR30 Diffuser on your Ecotech Radion LED light you will instantly see a better balance of light throughout your aquarium. PAR tests have proven that even though the overall peak PAR numbers will decrease, the lower light areas will actually receive more light from a diffused source. The overall light loss is around 20%, and since a majority of us do not use even 80% of the available lighting output, the PAR loss can be combatted by increasing the overall power delivered to the LEDs. Increased Spectrum BlendingDiffusing LED lights greatly helps blend the overall spectrum into one cohesive light source. Traditionally aquarium LEDs have used optics to increase the penetration of the light, but doing so actually makes each LED into its own little spotlight, making it harder for colors to blend. With the overall amount of light available in modern reef tank LEDs, more power is not exactly the best thing, and throughout our testing, we have found that evenly spread light that is blended properly is more important for coral health and growth. Decreased ShimmerLED lights are known for producing a lot of shimmer, also known as the "disco-ball effect" and the Ecotech Radion Diffuser directly attacks this problem head-on. With the overall goal being to mimic the natural sunlight or metal halide shimmer effects, the XR30 Diffuser is not perfect, but it gets much closer than almost any LED available today. Installation only takes a few minutes, and by unscrewing the bottom plate with a Phillips screwdriver, you can then attach the mounting adapter plate. The diffuser lens will then magnetically attach to the adapter plate. The magnetic attachment makes the diffuser lens very easy to clean
