After dwelled the samples left at room temperature for at least 30minutes before measurements. ＊Note4 , inserted into transparent linear pipe, and then the side Either end of sample was connected to a 1W white LED luminance and the color was measured at the 10, 20, 30, 40, 50, 60, 70, 80, 90cm points from the LED connection end. Outer diameter evaluation The outer diameter was measured at 6 points in the circumferential direction at points near the exact center in the lengthwise direction of each sample. method Length evaluation method Each sample was inserted into 10mm-width linear grooves, and the length was measured. *Note1　The luminance variation is based on human perception, and so the effect of the rate of variation was measured based on the Fechner's law which states that the strength of a sensation is proportional to the logarithm of the stimulus. Normally the range of -50% to +100% is considered to have no effect. *Note2　Color variation was determined by the effect of color variation based on the CIE chromaticity diagram developed by the International Commission on Illumination (CIE) in 1931 (ref. next figure) *Note3　The protrusion of core part with 1-2 mm length may occure at both ends due to shrinkage of cladding after a series of durability test. *Note4　Light flux: 45 lumens, Directional pattern (2Θ1/2）：110° 3M™ Light LightString String Ray Milky Flex 35 Graphs Ray Milky Flex 35 _ Graphs Color Variation - (X.Y.)

Dark spots may occur in illumination from the cut surface to about 10mm due to air gap between the core and cladding. 2.　Do not repeatedly bend, stretch, or subject the Light String to strong impact. This could damage it. 3.　Be careful not to damage the Light String when installing it. If it hits a hard object or scrapes against the floor, the cladding can be damaged, and the illumination quality can be adversely affected. 4.　Do not apply high tension to the Light String when connecting or securing it. If it is stretched, the illumination quality can be adversely affected. 5.　Please contact 3M about displacement absorption methods in the longitudinal direction. ･The technical information and data, recommendations, and other statesments provided in this document are based on tests which 3M believes to be reliable, but the accuracy and completeness of such information is not guaranteed. ・The user is responsible for determining beforehand whether a product is suitable for a particular purpose and assumes all responsiblity for any hazards inherent with the use of the product. ・If any product is proved to be defective, the seller and manufacturer are responsible only for replacement of the defective product. 3M is not liable for information and recommendations not included in this document unless provided for in a written agreement signed by authorized officers of the seller or manufacturer. 3M is a trademark of 3M Company.
