Solviden has 5 leds and an energy solar panel. Energy panel box has an internal replaceable AA battery ( used as accumulator ) and a light sensor.
The light sensor :

1st we need to cut shorted the wires of all leds … you have 5 leds :
– 4 leds have to be collected in a knot (cluster of leds)
– 1 led has to have the wire long and it will be inserted into candle (will play the role of candle flame)

 make wires shorted :

4 leds connected together :

At the end: 4 leds are grouped and 1 led is free and it has a more length wire (will be inserted into candle as candle flame)

#2 Work on candle : Jubla

The 1 led you have with long wire must be accommodated into candle and it simulate flame…
so you have to dig a tunnel into candle.

 I used the tip of a balloon to simulate the flame and hide the led (used as a cap)… see later

#3 Work on lantern : Rotera

You have to tinker a bit before you have the wires hidden and lantern assembled. Btw I have hidden all wires and placed the solar panel far from lantern so to be hidden. The lantern lights is on for more or less for 4 hours every night before that battery run-down.
