Ten Misunderstandings and Solutions of LED Lighting Upgrading

1. Different light distribution

This is probably the most common problem. LED lights and accessories tend to have more directional output. For example, if you use LED lights instead of halogen lights, there will be much less scattered light. This scattered light is actually useful, such as the lighting wall in the hotel corridor. Similarly, if you replace fluorescent lights with LEDs, the upper third of the wall will be dark.

>>The best way to avoid: buy samples first.

2. The lamp bought is too dark or too bright

If you are considering an operation similar to replacing a fluorescent lamp with an LED, don't think it's enough to consider only the light output of the matching fluorescent lamp (measured in lumens or LM). Because the LED light is directional, more light can be obtained from the LED. However, it should be noted that the light output mentioned in the data is likely to have moisture, which may not be so bright in fact.

>>The best way to avoid: buy well-known brands, or test samples.

3. The color temperature of the lamp is too cold

Generally, the color temperature of incandescent lamp is 2700k and that of halogen lamp is 3200K. If you replace these lamps with 5000K LEDs, the light will look very cold by comparison.

>>The best way to avoid: check the specifications and buy samples.

4 poor color rendering

The color rendering of light is represented by the color rendering index, namely CRI. In general, it is best to choose a lamp with a CRI of more than 80, or better, a lamp with a CRI of 90. One weakness of LED lamps is the R9 (red) value, but this item is not included in CRI measurement. Make sure that R9 also exceeds 80, otherwise the red will look messy and dim.

>>The best way to avoid: ask the supplier CRI value. If they don't, be careful.

5 lamp incompatible with dimmer

Dimmers specially designed for incandescent or halogen lamps may not be easy to use on LED lamps. At low levels, flickering often occurs. This is because incandescent lamp and halogen lamp provide a standard resistance load for dimmer, and LED circuit confuses this load. Sometimes both sets of electronic equipment want to compete for advantage, which will lead to component failure.

>>The best way to avoid it: test the dimmer with an LED, or add a "virtual load", such as an incandescent lamp.

6 lack of understanding of the brand

In recent years, a large number of new LED lighting suppliers have entered the market, so it is necessary to check the purchased brands. For example, what is the brand reputation, how long the brand has been out, whether it has passed the corresponding certification test, etc.

>>The best way to avoid it: learn about it online in advance.

7. Failure to pay attention to warranty

Will the supplier give you a warranty? Can the warranty be redeemed anytime, anywhere? Pay attention to the tips in small characters. Sometimes the lighting time is limited. Sometimes you must register online separately within 90 days to activate the warranty.

>>The best way to avoid: choose a reputable manufacturer and carefully read the warranty policy.

8 did not pay attention to the use of life

The generally accepted rated life of LED is the point at which its light output drops to 70% of its initial output, which is called L70. For example, you might see that the L70 has a rated life of 50000 hours. Similarly, there is moisture in many indicated service life, and some fail soon after installation.

>>The best way to avoid it: ask your supplier about their tests based on the L70 rating.

9 no long-term consideration

If the lamp breaks down after 18 months of use, you call the manufacturer and want to replace it. At this time, they may no longer produce this product and say they want to replace you with a new product. At this time, you should pay attention to that the new product may be very different from what you install on the ceiling; Or worse: you call them and find that they have closed down.

>>The best way to avoid it: if it is used in key places, you can buy additional as a spare.

10 poor lighting comfort

Using LEDs, glare problems come back, especially in the office. Uniform glare value (UGR) is a quantitative parameter to measure the subjective response of light emitted by lighting devices to human eyes, which should be below 19.

>>Best way to avoid: calculate UGR by computer or ask suppliers for UGR rating based on their installation examples.
