The LED rechargeable emergency light bulb is generally effective in terms of the actual situation, and it is not much different from other products. As long as it can complete the function, other products can complete it. The biggest disadvantage is that it is expensive (if you buy a low-quality one, it is easy to break, and even a well-known brand does not mean that the quality is good, but the after-sales service will be better).
The lighting effect is relatively good. Due to the luminous characteristics of the LED, the light is brighter, and it should be slightly brighter. Of course, this is under the premise of proper design. At the same time, another important feature is the long light-emitting time, and its power is slightly lower, of course, the conditions are the same.
In addition, you will also hear about lobbying when you buy that there are two other major features: one, energy saving; two, fast response (bright up); the so-called energy saving is actually not reflected in emergency lights. As a UPS power supply, only when the circuit is changed, the leakage current can be reduced and energy saving can be realized. However, under the same brightness requirements, the power of the LED lights will be lower and the battery life will be slightly longer, but the difference is not too big.
The other fast response refers to the period from power-on to light-emitting, which is six to ten nanoseconds faster than ordinary lamps. If it is not a special requirement, this feature is difficult to show in reality. It is suitable for fire emergency lighting. It is the most common lighting tool in fire emergency. It has a long emergency time, high brightness and automatic emergency function for power failure. The fire emergency light has the characteristics of low power consumption, high brightness and long service life. It is equipped with a power switch and a finger display light on the side. It is suitable for factories, hotels, schools, units and other public places to prepare for power outages as emergency lighting.
