TIR Lenses

“TIR” stands for Total Internal Reflection. EcoTech has engineered these lenses to capture more of the Radion LED light and direct it into your tank efficiently — making sure the light is going where your aquascape needs it most.

EcoTech offers two different TIR lens options for the Radion. The standard 80-degree TIR lens comes equipped on generation 2 Radion XR30w and XR30w Pro models. Our wide-angle 120-degree TIR lens reduces PAR at depth, but increases the coverage area.

Whether you own an original Radion that’s equipped with a reflector, or simply want to switch from a standard lens to wide angle, you can find what you need in our parts store.

Lighting Flexibility

EcoTech Marine’s TIR lenses direct the maximum amount of light possible, enabling you to get the most out of your Radion LED lighting.

From aquarium depth to coral spread, no two tanks are alike. With both original and wide-angle TIR lenses, you have the flexibility to customize your lighting to fit your reef’s unique needs.

All Radions come stocked with our original 80-degree TIR lenses – and now, our 120-degree wide-angle lenses are available to update your lighting fixtures. Both lenses are backwards compatible, working with all Radion generations.

Light Penetration and Spread

Have a shallow tank that would benefit from spreading par over a wider area? Go wide angle. Deeper tank with corals near the bottom? Stick with the original 80 degree lenses.

The 80 degree TIR lenses included with Radion Gen2 and Pro fixtures have been designed to provide optimal PAR for the majority of reef tanks. However, if you find that you are running your Radion fixture at less than 100% you may want to try the Wide Angle TIR lenses and unleash more of that potential with greater spread.

Not a problem! EcoTech has long committed to upgradability in its products.

All Radion lights have been engineered so that you can swap out the old lenses and replace them with new EcoTech lenses — no special tools or expertise required. Need help? We’ve created this online video tutorial to get you started.
