‘LED vs HID lights’ has long been a topic of debate in the row. Few years ago, research indicated that both scored the same in terms of efficiency and durability. But now times have changed and transformation in LED lighting industry has given modern LED lighting an edge in terms of lumen efficiency, lifespan and durability. However, the LED vs HID lights comparison is still going on due to lack of information.
Since HID lights are also being used to illuminate large spaces like streets, business spaces, and warehouses, business owners, real estate developers, and property managers are comparing HID lights with LED lights to gather information about the advantages of both. The comparison between LED vs HID lights is pretty common before making a bulk purchase. In view of painting a true picture, we bring for you LED vs HID lights comparison on the basis of lumens efficiency, lifespan, power consumption, cost and more.
The average light efficiency of LED light is 100 lumens per watt and expected to reach 150 lumens per watt by 2020. In comparison, light efficiency of HID light is 100 lumens per watt and depreciates with time. To put it simply, the brightness of LED light scores highest in LED vs HID lumens comparison.
The electricity consumption strictly depends upon the watt consumed. LED – the greatest lighting innovation of last century – provides bright light even with fewer watt capacities. The average electricity consumption of LED light is 30 watts per hour whereas HID light consumes an average of 100 watt per hour. Even while using 100 watts per hour, HID light fails to give as much brightness as a single 30 watt LED gives. This advantage is the most effective feature in LED vs HID lumens.
The color rendering index (CRI) of HID is 70+ whereas the CRI of LED light is 85+ on average. Higher the CRI, better the color rendering ability. Light sources with a CRI of 85 to 90 are considered good at color rendering. No wonder LED light scores higher when compared to HID lights.
The lifespan varies from light to light and strictly depends upon the working hours. The average life of HID bulb is 15.000 hours. LED light on the other hand is more efficient in terms of average lifespan. It has about 30,000 hours of average working life. LED products from technology driven suppliers like SeniorLED deliver even more.
In comparison to HID light, LED is more durable and does not break if after taking a harsh fall. LED is made up of plastic material & does not contain any filament whereas HID light is more fragile, made up of glass and hence easily breakable. This gives LED lights an advantage in harsh lighting environments like factories and manufacturing units. Have a look at QC process that guarantees supreme LED quality.
LED light does not require ballasts. Whereas HID light needs ballasts to operate. Generally, the ballasts used in HID lights increases the power consumption and need change after 1-2 years of use. Hence, in the long run, HID light ends up costing more in comparison to the LED lights.
Research has proven that light produced by HID light can be harmful for eyes since it doesn’t mimic the natural light pattern. Whereas modern LED lights are healthier and have evolved for modern work space and lifestyle. Circadian lighting products are well-being focused and bring huge advantages in terms of focus, productivity, and sleep cycle. Read more about human centric lighting.
Warm up period
HID light requires an extended warm up time for proper illumination (about 15 to 20 seconds warm up time). This is pretty long in comparison to LED lights which give immediate bright light and does not require any warm up time to reach its full potential. Hence, LED tech wins the LED vs. HID comparison here as well.
Environment & safety
LED light does not contain mercury whereas HID light has considerable quantity of mercury in it. Due to the toxic nature of mercury which is also difficult to dispose of, HID light is considered less safe in comparison to LED light.
HID lights are also associated with various other safety issues as well. HID light poses a risk for explosions and fires since they can reach temperatures that make them unsafe to touch. They also produce a substantial amount of ultraviolet (UV) radiation that can damage the skin, eyes, and fabric.
HID light comes with the warranty of 1-2 years whereas LED light comes with the warranty of 3+ years.
In the comparison between LED vs HID lights, LEDs come out as a clear winner in efficiency, average lifespan, durability, CRI and various other critical parameters. The only downside of LED light is the cost which is also steadily coming down as the global demand and production picks up.
