LED rechargeable emergency bulbs are LED energy-saving lamps that can continue to work in the event of a power outage or outage. There is a built-in battery inside the lamp. The battery capacity can be selected according to the use situation and the use time.
There are three types of batteries:
1. Lithium battery, its quality is better. There are capacities of 800 800 mAh, 1200 800 mAh and 2400 800 mAh. When fully charged, a 800 mAh battery can work continuously for 2-3 hours, a 1200 mAh battery can work continuously for 3-4 hours, and a 2400 mAh battery can work for about 6 hours.
2. Lithium iron phosphate battery, this battery usually has a comparative capacity of tens of thousands of milliamps. However, its low temperature resistance is relatively poor. So we recommend customers use lithium batteries. It's the same as the battery in our phone.
3. Lead-acid batteries. Its price is low, but its capacity is small. Generally 300 800 mAh and 600 800 mAh. It has a short usage time and can be used continuously for 1-2 hours.
So, now we are producing lithium batteries. It has high reliability and can be used continuously for a long time. It is recommended to buy it.
LED rechargeable emergency bulbs have 5w 7w 9w 12w 15w 18w, different brightness and solutions to solve your different needs.
