According to article 410.69 of the newly issued specification of NFPA 70 (National Fire Protection Association) and NEC 2020 (National Electrical Code), it is prohibited to use the line color (such as white and gray) reserved for the ground wire or neutral wire for the lamp control line, which will take effect from January 1, 2022. In other European countries, the dimming light shall not be yellow or green according to IEC60598-1.

According to these specifications, LO has unified the color of the existing outgoing LED driving power supply and dimming materials with purple and pink, so as to meet the specifications and provide customers with unified color marks, reduce the frequent modification of customers' wires and meet the requirements of relevant government standards, and facilitate customers' global promotion and unmodified MOQ production. The product renewal cost and certification fee of LUCE E OMBRA（路西恩布拉） will be absorbed by the company, and the selling price will not be increased.
