HID Light Meaning and History

HID or high-intensity discharge lights is an overarching term for a gas discharge light. These lights are the oldest type of electrical light, and they’re most commonly used when high intensity and efficiency are required.


HID lights are efficient and can produce high-quality light, but they may not be the best on the market.


The history and meaning of HID lights


HID light can be traced back to 1675 to a scientist named Jean-Felix Picard. He discovered that his mercury barometer will glow when shaken. This was the first sign of high-intensity discharge being observed. Progress was made in 1705 by Francis Hauksbee, who made a primitive version of the first lightbulb, and then again in 1857 with Heinrich Geissler, who used glasses and mercury to produce illumination. In 1901, Peter Cooper Hewitt created the first mercury vapor lamp. Finally, in 1913, Thomas Edison’s company shifted to sodium discharge lamps, proving more beneficial for light color, sustainability, and operational ability.


HID lights have their advantages. For example, they are efficient, and they can produce high-quality light. However, the disadvantages include the fact that roughly 30% of the energy emitted is infrared, or wasted energy. HID lumen output can significantly deteriorate as the bulb ages, they emit a lot of UV radiation, and they are also omnidirectional, meaning light needs to be redirected to be utilized.


Even though HID lights have been around for centuries, they may not be the best option for lighting your home. LED, or Light Emitting Diode, lights may be a better solution. LEDs have an extremely long lifespan, ten times longer than HID bulbs. They’re also strongly energy-efficient, high-quality, and low maintenance.


If you are looking for the most efficient light for your home, there are advantages and disadvantages to HID lights. They produce high-quality light and can do the job. However, LED lights last longer, are energy-efficient, and are low maintenance, making them a better choice for most applications.
