Very probable in the 18th century.
Yes, fluorescent lamps may be powered by DC but they need a DC lamp controller instead of an AC ballast and starter. The DC lamp controller is more complex. I have a 12V lantern with fluorescent lamp tubes.
People used candles , coal oil lamps and wood stoves, then later on they used gas until electricity was invented.
There are two types of lamps the tungsten halogen lamps and incandescent lamps. Tungsten Halogen Lamps are similar to incandescent lamps and produce light in the same manner from a tungsten filament; however the bulb contains a halogen gas (bromine or iodine) which is active in controlling tungsten evaporation, whereas the incandescent lamp suppresses tungsten evaporation.
Electrical lighting started in the late 1800s with the invention of the light bulb and the progression through carbon arc lamps. Electric lights became more common in the early 1900s.
They can be, but most will be powered by a mains AC to DC transformer.
Companies that manufacture battery operated camping lamps and sell the are the following: Dorcy, battery powered table lamp. Coleman, 4 D cell rugged.
A battery powered lamp is any of several types of lamp that provides illumination in coal mines and is designed to operate in air that may contain coal dust or gases both of which are potentially flammable or explosive. Before the invention of the electric light around 1900, miners used flame lamps to provide illumination. Open flame lamps could ignite flammable gases which collected in mines, causing explosions and so battery powered lamp were developed to enclose the flame and prevent it from igniting the surrounding atmosphere. Flame safety lamps have been replaced in mining with sealed explosion-proof electric lights.
You bet! It's called a flashlight, too. Some camping lamps use fluorescent bulbs and batteries to emit about the same amount of light.
There are no listings at Target for green lamps that are solar powered. There are listings for decorative outdoor lights that are solar powered, and some of these come in green.

A safty lamp was used by anyone who was working in an environment where dangerous explosive gasses may be present.So miners working underground and sewer workers are two examples.
Safety lamps are used in industry - mines, confined spaces.
