How it works?
Magnesium-air fuel cell technology has the same components as any other battery technology. There"s a magnesium anode and a gas-diffusion (air) cathode, with salt water as the electrolyte. it"s technically called an oxidation-reduction reaction. Using the oxidation-reduction reaction that occurs between the magnesium and the water.
The air cathode is the current collector for the system. The air cathode is a membrane that breathes, and allows oxygen from the air to enter the cell to facilitate the oxidation-reduction reaction.
Control House Assembly
Please change the salt water every 5-7 days
Replacing the Mg Bar
The Mg bar can be used for 25-35 days(QF-167A10 can be used for about 35 days, and QF-167A20 can be used for about 25 days). And when the Mg bar is dissolved, you just need to replace a new Mg bar. The LED String light is thus reusable.
There are many hundreds of LED bulbs on the market, so why shall you choose WQF?
Inflated claims about lifespan and color quality of cheap LED"s have led to some people being disappointed in the product and unwilling to invest further in the technology. But not all LED"s are born equal. WQF has spent 7 years sourcing the very best components and design to bring you a quality product you can rely on and at a reasonable price.
