V6P-YTT001SUN SPECTRUM LIGHT

Energy Saving Lamp Introduction ● Instant start, flicker free ● Conserves natural resources by at least saving 80% electricity than incandescent bulbs. ● About 10 times lamp life than a standard incandescent bulb. Notice For Use ● Never use with the following fixtures: Dimming circuit Emergency lighting fixtures Electronic timer fixtures Direct current fixtures ● Use only at the rated voltage and frequency circuit. The power voltage must be in the range of 120V±10%. ● Use indoor only. Never use it where water may drop on the lamp or where the atmosphere is humid. ● Do not use in enclosed fixture, Or the lamp’s life would be shorten. ● Always turn off the switch when replacing or cleaning the lamp. Remove and install it by grasping only the plastic portion of the lamp. ● Added weight may cause instability of free-standing portable lamps in which the distance from the bottom of the base to top of the lamp hold dose not exceed 3 times minimum vase width. Use only with portable lamps which are provided with lamp shade. ● This product complies with Part 18 of the FCC Rules but may cause interference to Radios, television, wireless telephones, and remote controls. If interference occurs, move product away from the device or plug either into a different outlet. ● Low EMC or Radio Frequency Interference. The lamp has filter circuits for Cutting out Radio Frequency Interference (RFI) and Complies with Electromagnetic Compatibility (EMC); they give out no harmful Radio Frequency radiation which tends to interfere with Radio, TV, and telecommunication, Mobile phones etc. ● The lamps are designed to start at very low supply voltages down to about 108VAC and even lower if required, they are also designed to tolerate short term very high supply voltage surges up to 132VAC. These features are most important for developing area where the supply voltage can fluctuate widely. ● They have short circuit protection ,all plastic materials used are certified Fire Retardant, they can be safely operated in the temperature range of -15°C to +65°C. ● This product may cause interference to radio equipment and should not be installed near maritime safety communications equipments or other critical navigation or communication equipment operating between 0.45-30MHz

The EUT was transmitting a test signal during the testing. POWER LINE CONDUCTED INTERFERENCE: The test procedure used was ANSI Standard C63.4-2003 using a 50ｕH LISN. Both Lines were observed. The bandwidth of the receiver was 10kHz with an appropriate sweep speed. The ambient temperature of the EUT was 25 °C with a humidity of 58%. RADIATION INTERFERENCE: The test procedure used was ANSI Standard C63.4-2003 using a ANRITSU spectrum analyzer with a pre-selector. The analyzer was calibrated in dB above a micro volt at the output of the antenna. The resolution bandwidth was 100 kHz and the video bandwidth was 300 kHz up to 1 GHz and 1 MHz with a video BW of 3 MHz above 1 GHz. The ambient temperature of the EUT was 25 °C with a humidity of 58%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor supplied by the antenna manufacturer and cable loss. The antenna correction factors and cable loss are stated in terms of dB. The gain of the Pre-selector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF + CABLE = FS 33 20 dBuV + 10.36 dB + 0.9 dB= 31.26 dBuV/m @ 3m ANSI STANDARD C63.4-2003 10.1.7 MEASUREMENT PROCEDURES: The EUT was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The EUT was placed in the center of the table (1.5m side). The table used for radiated measurements is capable of continuous rotation. The spectrum was scanned from 30 MHz to 10th harmonic of the fundamental. Peak readings were taken in three (3) orthogonal planes and the highest readings were converted to average readings based on the duration of "ON" time. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and vertical planes. The situation was similar for the conducted measurement except that the table did not rotate. The EUT was setup as described in ANSI Standard C63.4-2003 10.1.7 with the EUT 40 cm from the vertical ground wall. SHENZHEN MOST ELECTRONICS CO., LTD.
