Color Ranks
· The LEDs are packed in cardboard boxes after taping.
· In order to protect the LEDs from mechanical shock, we pack them in cardboard boxes for transportation.
· The LEDs may be damaged if the boxes are dropped or receive a strong impact against them,
· The boxes are not water resistant and therefore must be kept away from water and moisture.
· When the LEDs are transported, we recommend that you use the same packing method as Nichia.
Please refer to “TAPING DIMENSIONS” and “PACKING” on the following pages.
The label on the minimum packing unit shows ; Part Number, Lot Number, Ranking, Quantity
