Product Details:
The very important knowledge About solar light:
1.The LED quantity and LED brightness
SMD2835 LED parameter: luminous flux 5-30lm, power 0.1-0.5W.Simply , with the same electric current and voltage, 20pcs 30lm LEDs are brighter than 100pcs 5lm LEDs. Summary, more LED quantity doesn't mean higher brightness.
2.About battery capacity
Many batteries with fake capacity, the biggestest capacity for common 18650 lithium battery is 2400mah, but this kind battery price is very expensive. Normal capacity of 18650 lithium battery is 2200mah. The bigger capacity than 2200mah is fake capacity lithium battery. The weight of 2200mah lithium battery is about 45g, less than 43g,the lithium battery is fake capacity battery.
The standard capacity of 18650 LiFePO4 battery is 1500mah, this capacity is common use in the market.
3.The difference between lithium battery and LiFePO4 battery.
Lithium battery voltage is 3.7V, LiFePO4 battery voltage is 3.2V.
With lithium battery,After charge and discharge 300 times, the battery capacity decay to 80%.
With LiFePO4 battery, After charge and discharge 2000 times, the battery capacity decay to 80%.
LiFePO4 battery have better performance on temperature-resisting, no explosive incident happened so far. 18650 Manganese acid lithium battery is readily explosive, please keep away from Manganese acid lithium battery.
4.With the same solar panel,Is it better for larger battery capacity?
The answer is Negative. the battery capacity is depend on the power of solar panel.
The solar panel is larger, the charge efficiency is better. Such as 2 watt solar panel, charge electric current is 2W÷5.5V=360ma, there is only 5.5 hour effective charge time in sunny days, and one day charge capacity is 360ma*5.5 hour=1980mah.
So this solar panel just need 2200mah battery can full charged, no use to add larger capacity battery.
5.The LED brightness and electric current
The rated Current of 0.2W SMD2835 LED is 60mA, 5 pcs SMD2835 is 1W ,24lm LED luminous flux is 24*5=120lm/Watt; 30lm LED luminous flux is 30*5=150lm/Watt; Such as 30pcs 30lm LED in parallel, when electric current is 1800mA, luminous flux is around 30*30=900lm; when the electric current is 900mA, luminous flux is around 450lm.
6.About luminous flux(lm)
The most simple method of comparison: 25W bulb luminous flux is 250lm, 60W bulb is 600lm, if you want to know how bright the solar lights are, just need to compare with incandescent light bulb. The theoretical calculating method: such as 30pcs 26lm LED in parallel, when the electric current is 1000mA, per LED electric current is 1000mA÷30pcs=33mA, per LED luminous flux is 33mA÷60mA×26lm=14.3lm, namely the solar light luminous flux is 14.3lm×30pcs=429lm.
7.Lighting time
Only the lights with always lighting mode have the lighting time, the lights with motion sensor working time ways refer to the sensing times.
always lighting mode lights do not use the miniwatt solar panel and small capacity battery, lighting time is depend on solar panel power and battery capacity.
If need longer lighting time,with same capacity battery,that must reduce the luminance.
The lights with always mode are commonly used for emergency or special occasion, the solar lights are energy saving environmental protection products, so that the lights with always lighting mode are not belong to energy saving environmental protection products.
