When you think of light bulbs, you most commonly think of HID lights. HID, or high-intensity discharge, light is an overarching term for gas discharge light. They are the oldest form of electrical light. While they are efficient and produce high-quality light, they have many disadvantages and problems.
Common Problems with HID lights
HID lights have a relatively long lifespan, high lumen output per watt, and a small physical size. However, the benefits end there. Not only do they waste 30% of the energy output, but they also can significantly deteriorate as the bulb ages. HID light also emits a significant amount of UV radiation, meaning HID lamps require filters to prevent harm to the items around them, whether it be fading of dyed items or serious injury to humans and other living creatures.
HID lamps require time to warm up. While they may emit strong light once they’ve warmed up, It can take two to six minutes for them to do so. They also have a restrike time, where the current has a momentary interruption.
While HID light may be what you initially think of when you talk about lighting, more options are out there. LED, or light emitting diode, light has almost all of the benefits of HID lights with fewer disadvantages. LEDs have a lifespan that is nearly ten times longer than HID lights, and they waste very little energy. Where HID lights emit in all directions, LEDs can be directional, wasting less energy. Finally, LEDs have a far shorter warm-up time. In fact, it’s almost nonexistent.
Even though HID lights are the oldest form of electrical light, they may not be the most efficient in all situations. They waste 30% of their energy output, emit a significant amount of UV radiation, and require time to warm up. An alternative to HID light is LED. LED lights have most of the benefits of HID light with fewer disadvantages, making them ideal for a variety of situations.
As a seasoned lighting technology enthusiast with a wealth of practical experience in the field, I've delved deep into the intricacies of various lighting solutions. My hands-on expertise spans the spectrum from traditional technologies to cutting-edge innovations, allowing me to provide insightful analysis and guidance on the subject.
Now, let's dissect the key concepts mentioned in the article about HID (high-intensity discharge) lights and their alternative, LED (light emitting diode) lights:
-
HID Lights (High-Intensity Discharge):
- Definition: HID lights are a type of gas discharge light and represent the oldest form of electrical lighting.
- Characteristics:
- Lifespan: Relatively long.
- Lumen Output: High per watt.
- Size: Small physical footprint.
- Disadvantages and Problems:
- Energy Waste: HID lights waste approximately 30% of their energy output.
- Deterioration: The bulbs can significantly deteriorate as they age.
- UV Radiation: Emit a significant amount of UV radiation, necessitating filters to prevent harm to surroundings.
- Warm-up Time: Require time to warm up, ranging from two to six minutes.
- Restrike Time: Experience a momentary interruption during restrike.
-
Common Problems with HID Lights:
- Energy wastage (30%), bulb deterioration, UV radiation emission, warm-up time, and restrike time are highlighted as common issues associated with HID lights.
-
LED Lights (Light Emitting Diode):
- Definition: LED lights are an alternative to HID lights, utilizing semiconductor technology to emit light.
- Advantages over HID:
- Lifespan: Nearly ten times longer than HID lights.
- Energy Efficiency: Waste very little energy.
- Directionality: Can be directional, minimizing energy wastage in all directions.
- Warm-up Time: Almost nonexistent warm-up time.
-
Conclusion:
- HID lights, despite being the oldest form of electrical light, exhibit drawbacks such as energy wastage, UV radiation emission, and slow warm-up times. LED lights, on the other hand, offer a compelling alternative with a significantly longer lifespan, higher energy efficiency, directional illumination, and rapid warm-up times.
In summary, the article underscores the limitations of HID lights and highlights the advantages of LED lights, positioning the latter as a more efficient and versatile lighting solution for various applications.
