Notes when buying Dimmable LED lights
When selecting dimmable LED bulbs, consumers need to consider several key specifications to ensure they get the right illumination and performance:
Dimmable lighting fixtures are ideal for almost any space due to their flexibility, allowing tailored illumination for specific activities and moods. This adaptability is key for living rooms (socializing/relaxing), bedrooms (promoting sleep), offices (tasks/meetings), museums/galleries (spotlighting art), boutiques/shops (highlighting products),...
Non-dimmable LED light bulbs are a type of light that is designed to operate at full brightness and cannot have their light intensity adjusted. Unlike dimmable LED bulbs, they do not include the internal circuitry or driver needed to function with a dimmer switch. Using a non-dimmable bulb with a dimmer switch may cause it to flicker, buzz, or be damaged. These bulbs are a reliable and cost-effective option for situations where a consistent, bright light source is needed.

Dimmable LEDs offer highly adjustable brightness, typically providing a wide range from a very low 100 lumens up to 1600 lumens. This flexibility allows users to control illumination to suit various needs and ambiences precisely.
Conversely, non-dimmable LEDs deliver a fixed brightness, usually between 800 and 1200 lumens, depending on the bulb design.
Dimmable LEDs typically last between 25,000 to 50,000 hours, and their lifespan can be extended further when used with compatible dimmers and maintained properly. For example, if your LED has an L70 rating of 50,000 (meaning 70% of its original output will last for up to 50,000 hours) and you decided to keep this dimmed at 50% its entire life, you could receive 70% of this output for up to 75,000 hours (50% on top of the 50,000). This example shows a potential 50% increase in lifespan when the LED is consistently operated at 50% brightness.
In contrast, non-dimmable LEDs generally have a lifespan of 15,000 to 25,000 hours. While they offer robust durability, they lack the flexibility for dimming, limiting their versatility in various lighting applications. Find out more about How Long LED lights last.
Both dimmable LED vs non-dimmable LED are highly efficient, but dimmable LEDs are ultimately the superior energy-saving option because they allow users to reduce consumption proactively. Unlike non-dimmable LEDs, which run at a fixed wattage, dimmable models proportionally decrease power use when dimmed. This capability translates to significant cost savings: they use 90% less energy than incandescent bulbs, and last 25 times longer. Non-dimmable LEDs provide consistent savings but are restricted to their fixed, full-wattage consumption.
Dimmable LEDs also offer enhanced control over both the brightness and color of the light. By adjusting the flow of electricity to the light bulbs either by lowering it or turning it on and off, dimmers reduce the overall amount of power consumed. This helps you save on energy costs.

Dimmable LEDs are perfect for environments where adjustable lighting is needed to enhance ambiance, making them suitable for both residential and commercial spaces such as living rooms, home theaters, bedrooms, galleries, hotels,...
On the other hand, non-dimmable LEDs are ideal for general-purpose applications that require consistent and reliable illumination, including kitchens, offices, and outdoor security lighting.
Dimmable LED bulbs require compatible dimmer switches, such as trailing-edge or LED-specific models (often marked "ELV" or "MLV"), to prevent issues like flickering, buzzing, or reduced lifespan. Non-dimmable LEDs, by contrast, offer simplicity and reliability for standard on/off switches and circuits, fitting seamlessly into most setups without special needs.
Always check packaging for “not for use with dimmers” warnings to ensure safe, fixed-brightness use. Using non-dimmable LEDs with dimmers is unsafe, as they lack circuitry to handle reduced current, leading to flicker, noise, or damage. Pair dimmable bulbs only with rated dimmers to prevent mismatches.
Non-dimmable LEDs are more affordable upfront, making them ideal for general lighting. In contrast, dimmable LEDs are more expensive because of their advanced circuitry. While they have a higher initial cost, they offer greater energy efficiency and longer lifespans when dimmed, potentially leading to long-term savings.
Installing a non-dimmable LED bulb is very simple and straightforward. All you need to do is screw the bulb into any standard socket that is connected to a basic ON/OFF switch.
In contrast, the installation of a dimmable LED can be more complex. It's important to check whether the existing dimmer switch is compatible with LED technology. If it is not suitable, you may need to upgrade the dimmer to prevent flickering or subpar performance.

Yes, you can use dimmable LED bulbs in a regular socket, but they will only operate at full brightness unless paired with a compatible dimmer switch.
No, you should not use a non-dimmable LED bulb on a dimmable switch. It can cause flickering, buzzing, overheating, or even damage to the bulb and switch
You can tell if your lights are dimmable by checking the packaging, bulb markings, or product specifications. Most manufacturers clearly label dimmable bulbs. If it’s not marked, assume it’s non-dimmable.
Yes, trailing-edge dimmers are the best choice for dimming LED light bulbs. They are specifically designed to work with the lower wattage and electronic drivers inside LEDs, providing smoother, quieter, and more reliable dimming compared to older leading-edge dimmers.
The low wattage of LED bulbs might lead you to believe that you can connect many of them to the same dimmer switch. However, LED lights can draw a significant inrush of power when turned on, which may exceed their rated wattage. As a general rule of thumb, divide the dimmer's maximum load by 10. For example, with a 400W dimmer, you should use no more than 40W of LED bulbs. This means you can safely use eight 5W bulbs.
Yes, you can use dimmable LED bulbs with a regular switch without any issues; however, they’ll simply run at maximum brightness until you upgrade to a dimmer. And of course, you won’t be able to utilize the dimming feature, which makes them more expensive and is the main selling point of dimmable LED bulbs.
Yes, dimmable LED bulbs can safely and effectively work in fixtures controlled by non-dimming circuits, but they’ll always run at full brightness. Their dimming capability only activates when paired with a compatible dimmer switch.
