2) The welding: Each diode is connected to the circuit board by soldering, and all LED must be sold well, and if there is a bad welding, it may cause bulb does not light.
3) Batteries: there are two kinds of batteries, the ordinary and lithium types, although lithium battery is a rechargeable battery, but life expectancy is low as about 2 years, and LED life span is about 10 years, so you can choose according to the actual situation.
