LED Frequently Asked Questions

1) Should I change my light bulbs to LED?

Definitely yes, LED is the tendency for lighting, the traditional light will be forbidden to sale starting from 2023 and 2024:

  1. EU Commission adopts regulation to ban all fluorescent lighting by September 2023
  2. California joins the movement to eliminate mercury lamps

The absolute advantage of LED light:

  • Much higher efficiency

LED can be 100% more efficient than the traditional lights, which means to save much more energy then cost less.

  • Long lifetime

LED is quite robust for the lighting maintenance up to 20 times more than traditional light use without replacement.

  • Environment friendly

LED is green and clean energy without generating harmful toxins compared to traditional light.

2) How Do LED Lights Work?

LED lights are based on Light Emitting Diodes (LED) technology.

This technology uses semiconductors that light up when electrons are shot through them.

Unlike incandescent bulbs and fluorescents, LEDs usually converts a lot of the energy into light instead of heat.

3) Aren’t LED lights too expensive?

LED lights have higher upfront cost than traditional lights due to expensive raw materials and complex manufacturing methods, but they can save a lot of money over time through reduced energy use, low replacement and maintenance costs. If it's new construction or you're renovating your new home, installing LED lighting can sometimes cost the same as traditional technology, meaning you'll start to save from the start. Therefore using LED is a pretty cost-efficient ROI (Return On Investment).

4) Are LED Lights Dimmable?

In fact, LED is always dimmable, so it all depends on the LED driver when assembling the LED in the light. In most cases, all models of LED bulbs are available in a dimmable version. Before purchasing the product, you need to make sure that the product name or specifications mention "dimmable". Usually, manufacturers will indicate this on their packaging.

5) Why are LEDs considered a green technology?

LED bulbs are more efficient than most other light sources and consume less energy. They are also a completely mercury-free, environmentally friendly product. This new light source eliminates all kinds of pollution.

Secondly, their carbon footprint is very small and will not increase the world's carbon emissions; Thus, slowing down the rate of global warming and environmental degradation. Therefore, it can be called a true "green light source".

6) What are the advantages of LED lights?

  1. Long lifespan – 20 times working life than traditional light.
  2. Energy efficiency– up to more than 100% efficient than traditional light.
  3. High brightness and intensity.
  4. Zeroradiated heat.
  5. Design flexibility – flexible strip,linear module, specific design style.
  6. Instant lighting and the ability to withstand frequent switching.
  7. Low voltage operation than 36V– safe for human.

7) Do LED Lights Produce Heat?

LED is called “cold light source” - there is no heat radiance in the lighting spectrum, which is the infrared wavelength >740nm and there are plenty of infrared contained in the incandescent or halogen. LED covers only 400-700nm generally, therefore no heat generated then it does not affect the objects under the light especially for the ones are thermal sensitive.

But LED still generate heat, and this happens in the conversion from electrical input to the light. Actually LED generates significant heat so it is very important to control it, heat is one of the priorities affecting the lifespan of an LED light.

8) How long can LED lights last?

This question depends on how many hours per day you use the LED lights.On average, LED lights can last up to 50,000 hours, which is about 22 years if the fixture is only used 6 hours a day.

However, there are some that last longer, while others last for less than that amount of time.

Also, you should note that LED lights’ efficiency and output degrades gradually with time.

9) Can I use LED lights/Strips outdoors?

Some LED strip lights are suitable to be used outdoors. You need to check the IP rating – 65 and above is waterproof.

Indoor light strips are usually IP20 rated and they are usually not resistant to dust or liquids.

Outdoor light strips are usually rated IP65 or higher, which means they are dustproof and can withstand powerful water jets.

10)What is an IP Rating?

IP is an acronym for "Ingress Protection". It measures an item’s protection against solid objects (dust, sand, dirt, ect.) and liquids. The IP rating consists of 2 numbers. The first number refers to protection against solid objects (such as dust), and the second number refers to protection against liquids.

11)What does IP stand for?

When purchasing LED display screens for outdoor use, we often see words like "IP", which is an international code used to identify the protection level of lamps.

The protection level is usually expressed by IP followed by two numbers, which are used to define the protection level. The first number refers to the level of preventing solid foreign matters from entering, namely the dust-proof level, and the highest level is 6; The second number refers to the waterproof degree of the equipment, that is, the waterproof grade. The highest grade is 8.
