Relatively speaking, the service life of led lights is a little bit longer than that of cob lights. As far as the well-known brands on the market are concerned, cob can maintain a 10% attenuation within 2 years. Of course, these are not guaranteed by some small manufacturers. So when choosing, you need to choose a guaranteed brand, and clearly mark the light decay time of the light source when signing the contract.

In the general description, LEDs can be used for more than 50,000 hours, and some manufacturers advertise that their LEDs can operate for about 100,000 hours. Predictions indicate that high-quality LEDs can maintain more than 60% of the initial lamp brightness after 50,000 hours of continuous operation.

How long is the service life of led lamp beads?

In theory, LED lamp beads can achieve unlimited life, but when applied to lamps, it has a great relationship with heat dissipation and drive current. The greater the junction temperature, the greater the light decay, and the shorter the life. Generally speaking, the service life of led lamp beads is 30,000 to 50,000 hours. In fact, in our daily life, generally the lamp beads used in our led lamps are led lamp beads, so the service life is almost the same.

What is the difference between cob light and led light?

A led lamp is a lamp using light-emitting diodes as a light source. The led is a solid-state semiconductor device that can directly convert electricity into light. The cob light source is the high-efficiency integrated surface light source technology in which the LED chip is directly attached to the high-reflectivity mirror metal substrate. This technology eliminates the concept of the bracket, no electroplating, no reflow soldering, and no patching process, so the process is reduced by nearly a third First, the cost has also been saved by one-third. Generally speaking, it is a lamp that is more advanced and more eye-protecting than the LED lamp.

The difference between the cob lamp and the led lamp is that the led lamp is energy-saving, environmentally friendly, no flicker and no ultraviolet radiation, and the disadvantage is the blue light hazard. The cob lamp has high color rendering, the light color is close to natural color, no flicker, no glare, no electromagnetic radiation, no ultraviolet radiation, infrared radiation, and can protect eyes and skin.
