At present ,there are various emergency bulbs popular in the Indian market.
Which type is good quality?which type is with high technology? which type has better function? And which one will have the risks of surge and high voltage using in the Indian market?
Today I will teach you to choose the best one for you.
As we know there are many places with different electricity consumption problems, such as suddenly high voltage,high surge, short-term blackout......especially in UP and some other North India.
For emergency bulb, battery is the most important.All supplier will tell his customer that the bulb will work in 4 hours. but some battery labeled 1800mAh, some labeled 2000mAh,some labeled 2600mAh! why difference?
Two factors determine the emergency time(backup time)of the battery:
First,the brightness required by emergency,in another words,how many lumens from starting and how many watts from the starting?
In the market,some emergency bulb backup from 2.5-3W and below 300lm;some emergency bulb backup from 4W and 350lm; all required emergency working time above 4 hours!
At present,the best one is backup starting from4-5W and 400lm and emergency working time above 4 hours!
The driver consumption must be small,that is to say, the conversion efficiency is high!
From the technology point of view,it's possible to use 2000mAh Batteries for a 4-hours emergency working time for 9W emergency bulbs!
Why suppliers used above 2000mAh batteries? One reason is power consumption higher; the second reason is the batteries is not real full,just labeled a big number; the third reason is some customers really want long time for emergency working time!
In fact,there are almost no places where power will be cut down for more than 1hour.
For 4-hours backup time, some people used emergency bulb at the night market.
The charging time of ordinary emergency bulb usually takes12-15hours. The new technology was used in new type, the recharging time just need 4-6 hours, some drivers with turbine, some drivers with power indicator light...
Most emergency bulb drivers specifications like:
Type one: Input 90-305V, CCT 6000-6500, Ra >80, Surge protection >2.5KV, PF > 0.9, 80-90LM/W;
Type two: Input 90-305V, CCT 6000-6500, Ra >80, Surge protection >1.5KV, PF > 0.5, 80-90LM/W;
Type three: Input 100-440V, CCT 6000-6500, Ra >80, Surge protection >4KV, PF > 0.9, 100LM/W;
The three type Gosoled used new technology, recharging time is 4-6 hours, used 2000mAh Li-18650 buttery with BIS, 100LM/W , backup from 4W 400LM till 4hours working time.
It's new technology for emergency products,also can be used everywhere in India!
