The LED itself is composed of lamp beads one by one. If one or part of them does not light up, it will inevitably make the entire lamp dim. Lamp beads are usually connected in series first and then in parallel – so if a certain lamp bead burns out, a batch of lamp beads may not...

which can cause a crash when you use one in a fixture that’s wired to a dimmer switch, as in dual dimming mechanisms, frequently causing the light to strobe inaccurately as you dim the light up and down.
Here, we are referring to the input signal being PWM, and does not in itself indicate whether the LEDs themselves are pulsed using PWM (see below). This approach is useful for users building their own microcontroller circuits, including Arduino and Raspberry Pi projects which have the digital ...

Moreover, some of those LED lights can be strobed and provide an even more powerful burst of light for a short time period. Still others like Rotolights can be used as both temperature adjustable strobes and continuous lighting. In short you can mix and match LEDs and both conventional ...
Press and hold the button from5 to 10 sec: On the display you seeNight dim: OFF. This means the LEDs and displays will not be turned off if ambient light fall under 2 lux. Do the same to toggle back toNight dim: ON. This setting is saved in the non volatile memory, so it will ...

Anytime a regular lightbulb is dropped, there is a good chance the filament in the bulb will break. Since a LED does not have a bulb, that cannot happen. And since LEDs are lighter, they hit the ground with less force. What Features Should I Look for in a LED Flashlight?
But LEDs are the wave of the future. They cost a few dollars more to start with, but given their longevity and durability and power savings, they’re cheaper in the long run. But I doubt that I’ll ever give up completely on the incandescent lights, especially the bigger, brighter bulbs...
