Of course LEDs have advantages. Unlike high-pressure sodium lamps, they can be instantly turned on and off or dimmed.
Are LED street lights dimmable?
Dimming LED street lights is typically carried out by pulse-width modulation, which manipulates the duty cycle of a signal, so that the amount of ‘on’ time is reduced, but the spectral output of the light is unchanged [10,11].
Can outdoor LED lights be dimmed?
While most LED bulbs are now dimmable, not all of them are and not all of them dim in the same manner Since LEDs consume such a low wattage, many types of dimmers do not function with LED in the same way that they do with high wattage load incandescents.
Can you put a dimmer switch on an LED light fixture?
LED light bulbs can be used in light fixtures controlled by dimmer switches, but you may well find that traditional dimmers may not work—or may work inadequately—with some LED bulbs. The bottom line is compatibility. Some LED bulbs are designed for use with standard dimmer switches, while others are not.
How Much Can LED lights be dimmed?
In general most common mains LED bulbs will not dim below 10% and in a number of cases won’t dim below 30%. This can be a significant problem when you’re trying to create an ambience in a room. The other challenge is colour temperature.
Are LED street lights dangerous?
Reports produced in USA and Europe suggests LED street lighting is bad for humans in two main areas; the production of blue light that can affect melatonin production and glare that can damage to vision.
How do you turn off LED street lights?

What happens if you try to dim a non dimmable LED?
Some of the issues that may occur when a dimmer is incompatible with an LED lamp are: Flickering – Lamps will flicker (can also occur if a non-dimmable lamp is used) Drop-out – No light output at the end of the scale.
How can I tell if my LED lights are dimmable?
Look for an “LED” or “LED LAMP” marking on the bulb as well. Most residential LED light bulbs are dimmable, but some are not. In addition, the amount they can dim, or “dimming range”, also varies based on the light bulb used.
Are LED lights bad for your eyes?
The “blue light” in LED lighting can cause damage to the eye’s retina and also disturb natural sleep rhythms, according to a new report. … “Exposure to an intense and powerful (LED) light is ‘photo-toxic’ and can lead to irreversible loss of retinal cells and diminished sharpness of vision,” it said.
Do you need a special dimmer switch for LED lights?
Use dimmers designed for LEDs
The simple answer is to use only those dimmers that have been designed for LED loads. More of these dimmers are becoming available, and are designed to operate at far lower loads.

Why do my LED lights flicker on a dimmer switch?
LED bulb flickering can be traced in almost every instance to a non-compatible dimmer switch in the lighting circuit. … LED bulbs don’t have glowing filaments. When the dimmer switch goes off and on many times per second, the LED bulb becomes a flickering strobe light.
Is led ghosting dangerous?
The LED lamp, presenting a high impedance load to the circuit, does not cause this voltage to drop to near zero. This voltage then passes a current through the LED element, causing it to glow very softly. … Even though there is “voltage” present on the switched wire when the switch is off, it’s technically safe to touch.
Do LEDs last longer when dimmed?
LEDs can handle the on/off better than other kinds of light, but the “flickering” would be the factor in break-down. At 0V obviously the LED would last for a very long time so when the LED is off for an extended amount of time (dimmer on low- like 10%) the light should last longer.
