Q: Do I need ground wire for LED light retrofits?

It depends. If the design is IEC class I ( Class I vs Class II ), grounding is essential to ensure electrical safety. In the event of a fault, grounding provides an additional path for current to flow to the earth to prevent electric shock and fire risks. If the design is IEC class II, grounding is unnecessary because the Class II design is double insulated and live parts usually do not make the housing live, thus avoiding risks such as electric shock and fire. When carrying out LED retrofit projects, please select Class I and Class II protection levels as required and strictly comply with local electrical regulations.

Question 2

How long do LED retrofit lights last?

Accepted Answer

LED retrofit kits are often equipped with high-quality LED drivers and LED chips with good photoelectric conversion efficiency. Therefore, most of them will not fail completely (LED driver failure or LEDs burn out), but will slowly decay over time. Usually, the light decay is L70>50000hrs, and some can even reach L70>100000hrs, that is, after these LED light retrofits are used for 50000hrs or 100000hrs, their luminous flux can still be maintained at more than 70%. If these LED retrofit kits are used around the clock, the maintenance time is more than 6 years or 12 years.

Question 3

What is the difference between LED lights and LED light retrofits?

Accepted Answer

A LED lamp is usually an LED lighting device with a complete structure, including the luminaire housing as well as its internal parts-emitting components and LED driver. It can be installed independently without worrying about the type, interface differences and structural differences of the original lamps. In the case of retrofit LED lights, they usually have two important components: LED light-emitting components and LED drivers. In order to adapt to the original traditional lamps and lanterns (such as incandescent lamps, halogen lamps and other types of lamps and lanterns), we will add E27, E40, G9 and other interfaces for the product to facilitate the installation, which will greatly reduce the difficulty of replacement. However, if it is not possible to use the original interface, we need to equip the component with a bracket to be installed into the original lamps, which requires a certain degree of hands-on ability.
