The Very First Electric Lamp Was NOT Made by Edison

Long before Thomas Edison became famous for commercializing the incandescent bulb, the true earliest electric lamps were created by Sir Humphry Davy in the early 19th century—decades before Edison was even born. Davy’s experiments in 1802 and 1809 mark the real origin of electric lighting, and the difference between the two designs shows how rapidly electrical science was evolving.

Davy’s 1802 Lamp — The First Spark of Electric Light

In 1802, just two years after Volta introduced the first battery (the voltaic pile), Humphry Davy began experimenting at the Royal Institution.

Battery Power

Davy used a small voltaic pile—only a few hundred plates.

The power was limited, but enough to explore how electricity interacted with different materials.

Lamp Design

Two charcoal rods (carbon electrodes) were connected directly to the battery.

When the rods touched and were pulled slightly apart, a small, brief spark or weak glow appeared.

Performance

The light was faint and short-lived.

In the same year, Davy also heated a platinum strip to incandescence using electricity—an early ancestor of the incandescent filament.

This was the first time in human history that electricity produced light in a controllable way.
But it was only the beginning.

Davy’s 1809 Lamp — The First True Electric Lamp

Davy’s 1809 demonstration changed everything. This was no longer a scientific curiosity—this was the first powerful, sustained electric light ever shown to the public.

Battery Power

The breakthrough came from an enormous 2,000-cell battery, one of the most powerful electrical sources on Earth at the time.

This massive battery produced far higher voltage and current than his earlier experiments.

The same battery also allowed Davy to isolate new elements like sodium and potassium.

Lamp Design

Two horizontal carbon rods were connected to the battery.

When separated slightly, a bright electric arc formed between the tips.

Performance

This was the world’s first electric arc lamp.

The arc could stretch up to 4 inches (100 mm).

Witnesses said the light was as bright as the sun, flooding the room with intense white-blue illumination.

Davy called it an “arch lamp” because the arc bent upward due to rising hot air.

The major limitation:
The carbon rods burned away quickly, making it impractical for daily use—yet it proved for the first time that electricity could produce powerful artificial light.

Conclusion

The core principle in both 1802 and 1809 was the same—using electricity to heat or excite carbon until it glowed.
But the scale of power changed everything.

1802: The first spark of electric light.

1809: The first true electric lamp—decades before Edison.

Edison did not invent electric light.
He perfected the long-lasting, commercially viable incandescent bulb, but the first electric lamps belonged to Humphry Davy, the true pioneer of electric illumination.

NVIDIA NVLink Spine - The 130 TB/s Neural Backbone for AGI
The NVIDIA NVLink Spine, a core component of the GB200 NVL72 system, is an engineering marvel designed to serve as the high-speed data backbone for the world's most powerful AI supercomputers. It allows 72 GPUs to operate as a single, coherent entity for training trillion-parameter AI models.

Datacenter Network Card Specs :
The NVIDIA ConnectX-7 offers a maximum bandwidth of 400 GbE or NDR InfiniBand speeds. It uses QSFP112 or OSFP connector ports which accept either fiber optic cables (for longer distances) or Direct Attach Copper (DAC) cables (for short, in-rack connections).

The newer NVIDIA ConnectX-8 SuperNIC doubles that performance, providing a maximum bandwidth of 800 GbE or XDR InfiniBand. It uses the same OSFP or QSFP112 style ports, which also accommodate both fiber optic and Direct Attach Copper media to achieve the high speeds required for AI supercomputers. #technology

Flying fish are abundant in the tropical and subtropical waters of the Pacific Ocean and include about 40 different species globally. These fish do not engage in powered flight but use their highly modified, wing to glide above the water's surface to escape predators.
