![]() ![]() For example, an IP65 rating means that the device is protected against dust and low-pressure jets of water from all directions.Super Bright LED Solar Lamp 200 Lumens LED lights up all night, ABS plastic shell, withstand all kinds of weather, shockproof and super water resistance (IP44) and durable over time. Many models have an IP rating: a two-digit number that indicates the level of protection against the intrusion of dust and moisture. Manufacturers try to make their product prone to extreme weather at least to some degree. The brightness lets you know how illuminating the lights are and give an idea about the distance coverage. The lumen rating of solar-powered flood lights ranges from 300 to 1000 lm on average. You can get the same amount of light with a 10-watt LED bulb.Īs a rule of thumb, you can use the following conversion ratios to estimate the lumen output of light based on its wattage: For example, a 60-watt incandescent bulb typically produces around 600-800 lumens of light. Lumens are a more accurate way of measuring light output than wattage because different types of light bulbs produce different amounts of light for the same amount of energy. Lumen (lm) - a unit of measurement that is used to quantify the amount of light emitted by a light source. They last for 2000-5000 charge cycles which translates to at least a 5-year lifespan. This is the most modern subtype of lithium batteries. Lithium iron phosphate (LiFePO4 or LFP) batteries.This type is especially prone to temperature fluctuations, overcharging and deep discharge. ![]() Lead-acid batteries have an estimated lifespan of 200-300 charge cycles. This is the oldest battery type and the cheapest one as well. However, they have a higher self-discharge rate and they are charged slower. These batteries tend to last just as long as Li-Ion ones while being cheaper.
