The material used to make synthetic rocks is polyethylene and polyresin. Both of these materials are tough by nature. But when they are used for making synthetic rocks, they are injected with toughening substances to make sure they are resistant to cracks, scratches, and the weather. The bulb is inserted into the rock while the solar panel is attached on top of the rock. In any case, neither the bulbs nor the solar panels are in a favorable position for loosening or damage.
- Floor lamps can last a life time if used properly. So if you find a good looking lamp, make sure that it is of a good quality and is durable. Check how sturdy or heavy it is and if the finishing and painting are smooth or not. A floor lamp should be heavy enough not to fall to the ground with the slightest nudge or shove.

A lumen (lm) is the measure of luminous flux (light in transit), which is defined as light power as perceived by the human eye. When the metric area over which luminous flux is spread is taken into account, the SI measurement of illuminance, or lux (lx), is used. Alternately, when non-metric (foot) area is calculated, the non-SI footcandle (fc) unit is used to measure illuminance. Mathematically, one lux equals one lumen per square meter, or 1 lx= 1 lm/m2. Conversely, one footcandle equals one lumen per square foot, or 1 fc = 1 lm/ft2. Finally, one footcandle is approximately equal to 10.764 lux.
