UV-Filter sleeve T8-ASR-LY5, yellow, 470 nm, 90 cm for 30W CFL tube

UV filter sleeve METOLIGHT ASR-LY5-T8-090, yellow

Filter sleeve for CFL-Tubes, T8, 90 cm, 30 Watt, blocks light below 470 nm, yellow.

METOLIGHT ASR-LY5 filter sleeves are made of glass clear, breakage resistant polycarbonate sleeves with double layer inner filterfoil C10 and LY5 that blocks light below 470 nm. Thus, harmful UV light is absorbed.
Since only the light components below 470 nm are filtered out of daylight, only yellow-red colors remain visible to the human eye. The filter sleeve is therefore ideal for use with T8 CFL-tubes in electronic labs, coating areas, PCB coating, solar panel coating, Chip-Industry, printing areas, manufacturing areas where UV-curing inks, laquers, resins are processed, and wherever UV-free room lighting is required, in so called "yellow rooms".

The version ASR-LY5 compared to ASR-G10 is much brighter to the human eye. However some uv-curing inks, laquers, resins exposed at 360 - 380 nm have a second sensitivity from 420 to 480 nm. For such products we recommend to use the ASR-G10 sleeves.

In order to block the UV component in daylight in windows we offer UV filter foil SFLY5

The UV filter sleeve can be simply slided over T8 - 26 mm CFL tubes and then centered with the 2 supplied end caps. Please note that the outer diameter in the tubes increases to about 32 mm

Available sizes:
We offer all common standard lengths suitable for T8 CFL tubes 60 / 90 / 105 / 120 / 150 cm, other lengths upon request


Technical data:
Material: Polycarbonate
Length: 90 cm
Inner diameter: 30 mm
Outer diameter: 32 mm
UV-Blocking: light <470 nm

Notes:
The UV coated filter foils are inside the carrier sleeve. The filtering effect decreases with the passage of time, since the UV filter degrades slowly by the absorption of the UV light. How long the filter effect lasts is determined by the amount of UV light and the time of lit on luminaires. CFL-tubes can emit up to 10% of UV radiation, depending on brand and model. As of ourt experience the filter sleeves can work 3-5 years and longer. It is therefore necessary to check the effect at regular intervals (eg every 6 months) with a suitable UV meter. The UV filter effect is reduced at light wavelengths below approx. 350 nm.


Important to know:
While using the filter sleeves it is highly recommended to drive the CFL tubes only on electronic ballast or at least using an electronic starter instead of old style glimmer starter, because CFL tubes then might get way too hot. For HO (high Output) CFL-Tubes these sleeves are not generally suitable since some of the tubes get too hot. In such cases we recommend not to light up more than 2 hours. 

Cleaning:
The filter sleeves must not be cleaned with acidic, alkaline or abrasive cleaners, as these can dissolve the emulsion. Use only lukewarm water and a lint-free cleaning cloth (no microfiber cloths!) and wipe the film with only slight pressure.
