The FTS-SS is designed specifically for an obsolete Luxeon LED. This lens is not compatible with the Rebel line of LEDs. We are no longer stocking the FTS-SS, however it is still available to order.

The Ring Spacer is required to couple Lambertian FHS lenses directly onto Lambertian LEDs if you are not using a staked holder. This ring is compatible with Luxeon III and V Star Lambertian LEDs.

Ring Spacers are included with each lens holder. Only order this part if you need additional spacers.
