Will you choose a light bulb?

light bulb
The following large paragraph of English is extracted from the US Department of Energy:
When shopping for lighting, you can now use the Lighting Facts label and lumens to compare bulbs and purchase a bulb with the amount of brightness you want.
The Lighting Facts Label
U.S. Department of Energy
The Federal Trade Commission requires the Lighting Facts label on all light bulb packages to help co nsumers easily compare energy-efficient bulbs. The label includes:
Brightness, measured in lumens
Estimated yearly energy cost (similar to the EnergyGuide label)
Lifespan
Light appearance (from warm to cool)
Light appearance, measured by correlated color temperature (CCT) on the Kelvin (K) scale, from warm to cool.
Like the helpful nutrition label on food products, the Lighting Facts label helps you to understand exactly what you are buying and to buy the lightbulbs that are right for you.
Lumens: A New Way to Shop for Light
In the past, we bought lightbulbs ba sed on how much energy, or watts, they use. Wouldn't it make more sense to buy lights ba sed on how much light they provide?
When you're shopping for lightbulbs, you can choose your next lightbulb for the brightness you want by slit lumens instead of watts. A lumen is a measure of the amount of brightness of a lightbulb -- the higher the number of brightness of the lightbulb The lightbulb.
If you're replacing an inefficient 100W bulb, look for an energy-saving bulb that puts out a bout 1600 lumens. To replac a 60W equivalent, look for a bulb with a bout
So when you're looking for a new bulb, look for lumens -- or how bright the bulb is. Now that's a pretty bright idea!
The translation is as follows:
When you are shopping for lighting products, you can now compare the lumens values ​​on the parameter labels attached to the lighting products to select the products you want to buy.
Lighting parameter label
The Federal Trade Commission requires that the content on the lighting facts label on all bulb packages can easily help consumers compare energy-saving bulbs. The label content includes:
• Brightness, the lumen value obtained from the actual test.
• Estimated annual energy savings
•life
• Light color (from warm to cool) is measured by the correlated color temperature (CCT) unit is Kelvin (K), from the warm color of low color temperature to the cool color of high color temperature.
Just like the label on the nutrition, the lighting parameter label can help you accurately understand the bulb you purchased and how to buy the bulb that suits you best.
Lumens: A new way to pick lamps
Previously, we bought bulbs based on how much energy was consumed or the number of watts consumed. Is it more meaningful to discern how much luminous flux a light bulb can emit? When you are ready to buy a light bulb, you can choose the light bulb you want to buy based on the brightness, not the wattage of the light. The lumen value is a measure of the brightness of a light bulb - the higher the lumen count, the brighter the light bulb. If you replace the previously low-energy 100W bulb, choose an energy-saving bulb that can output 1600 lumens of light. Instead of 60W, buy one that can output 800 lumens. So when you are preparing to buy a new light bulb, focus on the lumen value - the brighter light bulb. This is a good way!
Seeing this information on the US Department of Energy website, it is very intuitive to tell consumers how to pick and do the training. If the domestic industry alliance can also be considered for consumers in this way, our industry will develop better! Of course, how to choose a light bulb is not just based on the amount of light flux.

Base site lead-acid battery protector system is the smart resonance pulse technique for 6V/36V cell battery or 6V/36V battery pack in series with 3PCS 2V/12V cells. It is working as a new generation of high-tech products for daily battery maintenance in telecom base site or electrical power system.
It utilizes the energy from battery self-power or floating power supply, to produce a unique smart electronic pulse, then feed back to the battery through the output line, Resonance with coarse and hard lead sulfated crystals in negative plates of batteries and converted to active substance under the reaction of pulse charging current which dissolve lead sulfated crystals, Keeping the battery working at a high efficiency. Under the disturbance by the smart resonance pulse, the new lead sulfate crystal is prevented from being formed, and the service lifespan of the lead-acid battery is prolonged 1~2 times than before.
There will be individual differences in State-Of-Capacity (SOC) and internal resistance (IR Value) of batteries after used for a certain number of years. It is called the battery unbalancing. Due to the total floating charge voltage of the rectifier remains unchanged and keeps constant, when the battery pack is in floating charging status, the floating voltage of the cells with larger internal resistance will be higher than that of the normal battery, resulting in the normal battery's floating voltage is lower. Batteries floating charged in this unbalancing way for a long time will cause the higher voltage cells seriously water dehydrated, and the lower voltage cell is in a state of under charged. This way of vicious spiral formed will accelerate the base site batteries premature failure.
Our protector system set a equalized charging function. If the terminal floating voltage of the battery system is higher than the standard value of protector system designed, the system automatically and smartly switches to the over-voltage balanced working state. When the voltage drops lower than standard value, it automatically changes to smart pulse maintaining state. The decrease of battery internal resistance and the improvement of the battery equalization lead to the battery lifespan prolonged.
