portable solar powered led light bulb
| Solar power system/ solar home light-SR-HL006 | |
| solar panel: | 5.5V/4W,High efficiency solar cell is from SUNTECH-POWER |
| Lithium battery: | 3.7V 4400mah |
| Led source: | 3W (6pcs LED cell, each is 0.5W),power adjustable:1W/2W/3W, 300LM max. |
| Luminous flux: | 1W 84lm, 2W 164lm, 3W 240lm (if without the lamp shade it can be 300LM). |
| Working time: | 1W ≥ 15hours; 2W ≥ 8hours; 3W ≥ 6 hours; |
| For example: | When the battery is full charge, It has power available is 3.7V*4.4AH=16.3W, and the loss ratio is 10%, so 1W bulb is 16.3W*(1-10%)/1W=14.7hours; 2W bulb is 16.3W*(1-10%)/2W=8.2hours…. |
| Charging time: | charge by solar panel, it is about 8-10hours; If use USB connect to computer, it is also 10 hours; If use a charger or adapter with 1AH output, it is only 6-8 hours. |
| USB out put: | 5V 1Ah Max. |
| Cable: | solar panel cable 5m; USB cable 30cm. |
| Life Time: | The battery can charge and discharge at least 500 times(normally is 500-800 times). For example:if charge and discharge every day, it can use 500/365≈1.4 year. Normally no one can charge and discharge every day, so the life time is more longer. |
| Warranty: | 1 year guarantee |
