C20 – Clear (Up to 400 nm)

LY5 – Light yellow (Up to 470 nm)

The Encapsulite LY5 sleeve contains a specially coated light yellow filter, absorbing ultraviolet light up to 470 nanometres. Designed for more UV sensitive materials and locations whilst giving utmost brightness.

G10 – Gold (Up to 520 nm)

Safe up to 520 nanometres and designed for locations such as clean rooms, plate making facilities, circuit board and semiconductor manufacturing plants.

UV400 (Up to 400 nm)

This product from Encapsulite was developed for museums, archives and libraries to filter out harmful UV from fluorescent tubes while still retaining good lamp colour temperature. The UV400 cuts out all UV up to 400 nm. The new UV400 avoids interfering with the fitment of louvers and diffusers often used in conjunction with a UV filter.
