About our T8 Clear UV Tube Guards (Case of 24)
T8 clear UV tube guards hinder photochemical degradation in textiles, historical documents, and works of art. Intended for use in museums, art galleries, libraries, retail establishments, and other areas where the prevention of UV degradation is critical.
- Transmittance: has 0% transmittance below 395 nanometers (nm)
- Material: made of UV-filtering clear polycarbonate plastic (approximately 1/32in thick); may easily be cut to shorter lengths with a saw
- 4ft Long: nominal length of 4 feet
- Diameter: the T8 clear UV tube guard with an outside diameter of 1.235 inches is designed to fit on a T8 linear fluorescent lamp that measures 1.0 inch (8/8in) in diameter
- End Caps Included: includes two, black, opaque end caps for each tube guard
- Not for High Output Lamps: these UV tube guards should be used only with standard T8 linear fluorescent light bulbs - not with T8 high output lamps; T8HO lamps will melt these UV tube guards.
- 10-Year Expected Life: Generally, the rated life of UV tube guards is considered to be up to 10 years. They are also made of UV-stabilized material which helps guard against degradation, yellowing, or becoming brittle over time. However, there are almost always other factors that are unique to the situation in which they are used that may shorten the life of the tube guards such as exposure to “harsh” atmospheric conditions including chemical vapors. Thus, you may want to consider replacing the clear UV tube guard when a burned out T8 light bulb is replaced.
- Minimum Order: must be purchased in case quantities only of 24/case

Polycarbonate is normally NOT UV Stop material...in most cases ACRYLIC is used is this normal to offer a Polycarbonate material?
By Jacob from Pegasus Lighting on May 7, 2014
All that I can tell you is that these UV tube guards have 0% UV transmittance below 395 nanometers (nm). I have never seen an acrylic tube guard.

Is there a drop in lumens in using the filter?
By Jacob from Pegasus Lighting on January 7, 2015
Answer:Yes, light output is reduced when a tube guard is used over a fluorescent light bulb.
By Vern Patterson from Colorado Springs, CO on January 7, 2015
Thanks for your quick response to my question. Do you have an estimated % in drop in lumens for your UV shielding? A rough estimate is fine. I am trying to compare the difference between LEDs and fluorescent for a preservation purposes at a museum where I volunteer.
By Jacob from Pegasus Lighting on January 8, 2015
Answer:Vern, you can expect 85% transmission of light, so a 15% drop in lumen output.

Are these tubes UL listed?
By Jacob from Pegasus Lighting on October 25, 2012
Answer:These tube guards do not carry a UL listing.
