LC7730 source: SMD LED Input: 16V / 640mA Power: 12W Shape: 300x300mm Installation: Ceiling-mounted color temperature: 6000K / 3000K CRI: Ra> 800 ° Surface Color: Silver Shell: Aluminum Lighting Features: 1, high quality, The light source adopts imported LED, the shell is made of aluminum 6063-T5 excellent thermal performance. 2, cold light, no heat radiation according to the article, to ensure that goods from heat damage. 3, lamps with light projection angle precision, no light pollution. 4, high luminous efficiency, energy saving, long life. 5, no flicker, the human eye does not produce fatigue. 6, the color is good, meticulous craftsmanship and can show the true color of goods. 7, exquisite style, low-voltage power supply, safe and environmentally friendly. Applications: for jewelry stores, art galleries, interior image printing, optical shops, art hall, all kinds of exhibition hall lighting and other needs of accent lighting applications. Instructions: 1. Enter the low-pressure lamps, LED power supply when connected to distinguish between the positive (red) electrode, negative (black) pole, we must act in parallel connected light bar. 2. The need to take before the power failure lights, LED light bar and the power connector, the first output of the power supply of the red, black wire touches to put more than electricity. Be sure to first light bar and LED power is connected, it is energized, give non-LED power supply output line then touch the wires connected to the lamp. 3. Do not pull the lamp cord, so as not to damage the line Larsson off.
