Dimmable LED-Lighting Shade

How to Tailor Your Light Intensity with Dimmable LEDs

In the not-so-distant past, incandescent bulbs were the go-to lighting source. However, the advent of LED technology revolutionized the industry. LED lights provide energy-efficient illumination and last significantly longer than their incandescent counterparts

Dimmable LED lights are a specific type of LED lighting that allows users to adjust the intensity of light they emit. Unlike traditional lighting sources that are either on or off, dimming LEDs offer a range of brightness levels. This adjustability adds a new dimension to lighting, allowing for enhanced ambiance and energy savings.

LEDs work on Pulse-Width Modulation (PWM)

Dimmmable lights operate through a process called pulse-width modulation (PWM). This involves rapidly switching the LED on and off at different intervals. The longer the LED is on, the brighter the light appears. Conversely, shorter on periods result in dimmer lighting. This rapid switching is imperceptible to the human eye, creating the illusion of smoothly adjustable brightness.

Some important facts

  • The earliest LEDs emerged as functional electronic components in 1962, initially emitting low-intensity infrared (IR) light
  • In February 1969, Hewlett-Packard made a significant breakthrough. They introduced the HP Model 5082-7000 Numeric Indicator, which became the pioneering LED device
  • The LED light market is projected to grow from US$75.8 billion in 2020. It is expected to increase to US$160 billion in 2026
  • The Manapakkam, Chennai office of the Indian IT company iGate made an investment. They spent ₹3,700,000 (US$80,000) to light 57,000 sq ft (5,300 m2) of office space with LEDs
  • The firm had an expectation that the new lighting would pay for itself within 5 years

Difference Between Dimmable and Non-Dimmable LED Bulbs

FeatureDimmable LEDNon-Dimmable LED
Dimming CapabilityCan be adjusted to various brightness levels using compatible dimmer switches.Operates at a fixed brightness level without the ability to be dimmed.
VersatilityOffers flexibility in setting the desired lighting ambiance for different situations.Provides a constant level of illumination without adjustable brightness.
Energy EfficiencyGenerally maintains high energy efficiency even when dimmed, as they consume less power.Maintains energy efficiency but operates at the same power consumption regardless of lighting requirements.
CompatibilityRequires compatible dimmer switches to ensure smooth and flicker-free dimming.non dim Works with standard on/off switches without any additional requirements.
CostDimming LED lights are often slightly more expensive due to dimming functionality.Non-dimmable LED Bulbs are usually less expensive.
InstallationInstallation process is generally the same as non dimmable LED Bulbs.Installation process is straightforward and doesn’t require any special considerations for dimmer compatibility.
Use CasesIdeal for environments where adjustable lighting levels are desired, such as living rooms, dining areas, and bedrooms.Suitable for spaces where consistent illumination without brightness adjustment is sufficient, like hallways and closets.
MaintenanceSimilar maintenance requirements as non-dimmable LEDs, with longevity and reliability being key features.Comparable maintenance needs to dimming LEDs, focusing on long lifespan and minimal replacements.

Types of Dimmable LEDs

There are several types of Dimmable Lights available on the market. But mostly type of dimming mechanism used can vary based on the Lighting model and manufacturer. Here are some common types;

Step Dimming

This type of dimming allows you to cycle through predefined brightness levels by clicking a button or rotating a dial. As well as each click or rotation changes the output level.

Continuous Dimming

These lights offer smooth and continuous dimming control. These further allow you to adjust the brightness level to your desired intensity. They often have a dedicated switch or control for dimming.

PWM Dimming

Pulse Width Modulation (PWM) dimming is a popular method used in many Dimmies. Additionally you rapidly turning the LED on and off at varying intervals to control the average brightness.

Touch Dimming

Some Dimming Lights feature touch-sensitive controls for dimming. You can swipe or touch a specific area on the light’s body to increase or decrease the brightness level.

Programmable Dimming

Certain advanced Dimmable Lights allow you to program and customize the dimming levels according to your preferences. They often come with a user interface or software that enables you to adjust the brightness settings.

Applications of Dimmable LEDs

Studio Photography

These Dimmies provide photographers with the flexibility to create desired lighting effects still life and product photography. The ability to adjust the brightness enables precise control over highlights and shadows. Thus these lights help in enhancing the overall visual impact of the image.

Outdoor Photography

When shooting outdoors, lighting conditions can be unpredictable. Dimmies allow photographers to adapt to changing light conditions and compensating for shadows. Further, this feature proves invaluable in capturing compelling landscape and wildlife photographs.


For videographers, these lights serve as a versatile lighting tool. Whether shooting interviews, documentaries, or narrative films, the ability to adjust the intensity of the light provides control over the mood and atmosphere of the scene.

Event Photography

The Dimming Lights find great utility in event photography, where lighting conditions can vary drastically. When you adjust the light output to suit the occasion, these let you to capture the spirit and atmosphere of indoor weddings or outdoor concept.

Tips for using dimming LEDs

Understand the controlsFamiliarize yourself with the operation of your LED unit, including brightness adjustments and other available settings.
Experiment with different brightness levelsTest various light intensities to find the ideal balance for your desired lighting effect and subject.
Consider the shooting environmentAssess the ambient light conditions and adjust the output accordingly to achieve a natural-looking result.
Modify the distanceChanging the distance between the light and the subject can have an effect on both the strength and the extent to which the light spreads.
Use diffusers or reflectorsEmploy diffusers or reflectors to soften or redirect the light, creating a more pleasing and balanced illumination.
Balance with ambient lightWhen using in low-light situations, ensure a proper balance between the light output and the existing ambient light.
Take test shots and review the resultsCapture test shots with different settings and review them on your camera’s LCD screen to assess the impact.
Adapt to specific shooting scenariosCustomize the foutput to suit specific shooting scenarios, such as portrait photography, still life, or action shots.
Explore creative lighting techniquesExperiment with different lighting angles, shadows, and highlights to add depth and drama to your images.
Continuously learn and practiceDevelop your skills by studying lighting techniques, attending workshops and other sessions.
