Answer:
The device was not very long lasting
Explanation:
Henry Woodward and Mathew Evans were two British scientist who invented first light bulb in 1860.
The challenge they faced while inventing light bulb was the log lasting light filament. Earlier filament was made up of carbonized paper which was not long lasting and has light for very less time period. Later they solve it by making carbon fiber filament derived from cotton and got patent for the same invention. But then because of financial issues they sold their patent to Edison.
Hence, the correct answer is "The device was not very long lasting".
