Choose the appropriate color temperature. If the LED fluorescent lamp is installed at a higher position, you can purchase a higher color temperature, such as: 6500K--7000K. The light color seems to be a little blue. In that way, the LED's light efficiency is relatively high, although it is a bit glaring, but because of the high installation position, the chance of direct eye exposure is small. If the installation position is low and there are many opportunities for direct eye exposure, you should use a low color temperature, which is close to daylight: if the color temperature is 5500K--6000K. The light is softer and the eyes feel comfortable.
The choice of LED fluorescent tubes also requires consideration of the appropriate power. The same energy consumption of LED fluorescent lamps, the luminous flux emitted by them is very different, and the high-quality, large-flux LED fluorescent lamps are used instead of the traditional fluorescent lamps, and it is possible to appropriately consider installing less. Do not substitute 1:1 with traditional fluorescent lamps. This way, it is more energy efficient. Zhongshan Guoan Torch Company, a subsidiary of CITIC Guoan, is the first to replace the high-quality LED fluorescent lamp produced by Ge Ri Optoelectronics in the workshop for energy saving and protection of workers' health. The 18W LED fluorescent lamp is much brighter than the original brand fluorescent energy-saving lamp 40W. The worker reacted too brightly, and finally removed half of it, the effect is still very small compared with the original two traditional fluorescent lamps.
Choose the appropriate appearance: the general LED fluorescent lamp in the user's concept still stays in the traditional fluorescent lamp stage. Therefore, no matter what the situation, the light is required to be the same as the traditional fluorescent lamp. Manufacturers add a soft board to the LED fluorescent tube to make the light look the same as the traditional one. In fact, the soft light board has a loss of light energy. Generally between 15-30%. If the installation position is high and the eyes are not easily exposed, you can consider using a transparent cover. In this way, you can choose a smaller LED fluorescent lamp, which will be more energy efficient.
The 85W Macbook Charger MagSafe 1 or MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Pro stays put safely. It also helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection.
When the connection is secure, an LED located at the head of the DC connector lights up; an amber light lets you know that your notebook is charging, while a green light tells you that you have a full charge. An AC cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel.
Designed to be the perfect traveling companion, the adapter has a clever design which allows the DC cable to be wound neatly around itself for easy cable storage.
This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode. It also powers the system if you choose to operate without a battery.
Compatible with MacBook Pro with Retina display.
