5 Things You Should Know When Buying UFO Led High Bay Lights

When we buying UFO led high bay lights, we face a variety of parameters, such as CRI, beam angle, lm/w, and so on. Sometimes it’s hard for us to understand. I will list the most helpful and most important aspects to help you pick the right UFO led high bay light.

1. Why are they so expensive?

UFO led high bay light as new commercial lighting; it uses a lens light distribution design, no extra reflector light distribution. Therefore, the traditional LED high bay light is not easily deformed during transport, which also results in relatively low transportation costs.

UFO led high bay light fixtures to have excellent color rendering, so the real color is more genuine. It eliminates the suppressed emotions caused by the high or low color temperature of traditional lamps, which provides visual comfort and improves the work efficiency of the workers.

 Made from LED, this high-efficiency lamp produces 110 to 140 lumens per watt, 30% more than standard high-bay luminaires. Waterproof dimming driver features a rugged, lightweight, die-cast aluminum housing for exceptional durability.

Excellent waterproof and dustproof performance that makes them can be widely used in many harsh environments. More importantly, their life expectancy exceeds 50,000 hours.

2. Where will you use the most?

UFO commercial LED bulbs deliver unparalleled performance in a compact, lightweight package for a variety of high bay applications. You can use them in the following places:

• Warehouse
• Shop
• Stadium
• Garage
• Industrial Plants
• Exhibition area

3. Focus on Lumens, not Watts

Why lumens? Indeed, more efficient light bulbs consume less energy to produce the same brightness: they consume less energy. We use lumens per watt to measure the energy efficiency of high bay LED light: the higher the value, the better the performance! At the same power output of 100 W, different light output luminaires produce different levels of lighting. 

As a result, relying solely on watts alone prevents consumers from comparing traditional incandescent light bulbs to more efficient bulbs, such as compact fluorescent light bulbs.

LED is currently the most stable, safe, environmentally friendly and light-efficient artificial light source used by humans.

The curves of each color represent the different types of efficiency of synthetic light sources (lights), all of which change over time.

The deep blue curve represents the incandescent bulb: in the 1880s, when the incandescent lamp was invented, its light output was very low, almost less than 20 lm / w.

Then, with the evolution of the times and the improvement of the technology, the luminous efficiency of the incandescent lamps continues to grow. However, it can reach at most 20lm / w, which is due to its principle of illumination.

The halogen lamp has a general upward trend in the development of the river, but its principle also limits its luminous efficiency cannot be improved significantly.

Although other light sources have some improvements, they are not as fast as LED lights.

Since the beginning of the use of white LED lamps, it has only been used in a few years to increase its light output to 160lm / w; until recently, its luminous efficacy is still increasing rapidly.

4. Why we require UL or ETL?

In electrical products, such as lighting fixtures, ETL & UL will be tested individually to ensure that they do not malfunction and that they do not cause fire or danger.

If a product is listed UL or ETL, or certified, it is considered safe for the public. That's why commercial building codes almost always require UL or ETL listings.

In terms of lighting, UL is a more general sign than ETL. But there is little difference between the two. UL and ETL are both recognized as nationally recognized NRTL or Test Laboratories. The US Occupational Safety & Health Administration (OSHA) regulates and recognizes NRTLs.

Of the manufacturers I contacted, not all luminaire manufacturers are UL or ETL certified. On the other hand, the cost of obtaining and maintaining accreditation costs thousands of dollars a year; In addition, UL and ETL certification procedures are stricter than CE certification in Europe. Not all products can easily pass the certification. How many high

5. How many UFO led high bay light bulbs do we need?

Before discussing the most appropriate quantity, power, and height for a high-bay luminaire, consider the brightness reference (lumen / m2) for different occasions.

Once we understand the lighting needs for different occasions, then we need:

1. Measure the width, height, and length of your store, garage or warehouse
2. Refer to the above table to manage your lux requirements.
3. Use the lighting design software like DiaLux to calculate the angle of illumination, wattage, mounting height, number, and the installation position of the lamps you need.

Not everyone is a lighting designer. But using these programs can save you hundreds of dollars. If you do not have this professional software, please explain to the owner of your lighting shop in 1, 2 points; they will give you a more accurate answer. Or discuss an electrician, you know, is also the right choice.

Conclusion

When you finish reading this blog, you may be able to focus on some key points when you buy UFO lamps. We highlight here the five aspects you need to pay attention to:

• LED lights are much more costly than HID/HPS lamps
• You can use them in Stadiums, Warehouses, Shop, Garage, Industrial Plants & Exhibition areas
• Luminous efficiency tends to be more worthy of attention than wattage
• Products should have ETL or UL certification
• Calculate the number of fixtures you require by the simulation to save money
