The index of 100 represents the best saturation. The color saturation Rg is used to characterize the color gamut index GAI (Gamut Area Index) of the light source, that is, the saturation degree of each standard color compared with the reference light source under the illumination of the test light source. Rf =100 is the maximum value, which means that there is no color difference with the color under the natural light source, and the color effect is realistic. Rf is Color Fidelity Index, it is from 0 to 100, it is similar to CRI, but it uses 99 sample colors. We can see that the higher the light efficiency, the more energy savingīesides CRI, you also need to care about Rg and Rf The figure below shows the new Erp's regulations on energy efficiency labels. The higher the value, the higher the energy conversion efficiency. It is the result of dividing lumen by power. In the LED era, power cannot be used as a parameter to evaluate whether the light bulb is bright enough, because the better the LED, the more lumens can be emitted with less power. One watt is equivalent to one joule per second, and it's a measure of power consumption that your power company uses to calculate how much energy you're consuming. The industry stipulates that the safe voltage is not higher than 36V, and the continuous contact safe voltage is 24V. So when the device asks for direct current, we need to connect wires as positive and negative electrodes. Safe voltage refers to the voltage that will not cause direct death or disability. The current always moves in the same direction. It may be a higher voltage or lower voltage than the rated voltage. But in some developing countries, it usually is not stable due to weak basic power facilities. In developed countries, the voltage is stable. It looks the same as a sine wave.įrom the picture, we can know the highest voltage is 311V, and 220V is near the avg value(you can understand it as simple). The value of voltage we said is a valid value the voltage value is different each time. Generally, there have to 2 kinds of voltage in different countries all over the world. This is the electricity that is used in most spaces. Lumen is the most important parameter when choosing the LED light you need. Comparing lumen output between different products will help you to buy the right LED lamp at a reasonable price. Different manufacturers using different technology and quality level, the energy conversion efficiency will be a big difference, low quality may be 60-70lm/w, and the high quality will be 100-120lm/w for the same lamp. That is no problem with incandescent lighting. Storage temperature: -20 degrees Celsius to +60 degrees Celsiusīecause incandescent lighting have the same energy conversion efficiency by different manufacturers, we are all accustomed to using watts to measure the brightness of a light. Operating temperature: -20 degrees Celsius to +60 degrees Celsius power consumption: 18 W/m (18W Warm White+ 18W Cold White)ĭimmable: yes, up to 0.1% with the appropriate PWM dimmers Flexible stripes can be easily separated with scissors at designated points and reused in new feeds. The LED strip has 3M tape on the back for easy on-site installation. Use with Constant Voltage PWM dimmers operated by KNX, DMX, DALI, Loxone, Homematic or Dresden Electronics. Just bright daylight during the day and a comfortable warm color temperature at night Circadian rhythm color gradient throughout the day, representing healthy light color (HCL) suitable for biological rhythms. "tunable white" (individual adjustment of brightness and color temperature), TILLUME DTW LED Flexible Stripe enables an unprecedented color temperature spectrum from 2200 K to 6500 K, ensuring the best possible light color in every application.
