However, they do offer a wide range of other features and options that make them a popular choice among smart home enthusiasts. If you’re considering installing Lutron Caseta dimmers in your home, it’s important to understand what they do and do not offer.
Key Takeaways
- Lutron Caseta dimmers are not TRIAC dimmers, but instead use a different technology.
- Lutron Caseta dimmers do not offer ELV dimmers, but offer a wide range of other features and options.
- Before installing Lutron Caseta dimmers, it’s important to understand their features and limitations.
Lutron Caseta: TRIAC Dimmer?

Lutron Caseta is a popular line of smart dimmers that is widely used in homes and offices. As a professional in the lighting industry, I have come across many questions about whether Lutron Caseta is a TRIAC dimmer. The answer is no, Lutron Caseta dimmers are not TRIAC dimmers.
TRIAC dimmers are a type of dimmer switch that uses a TRIAC (triode for alternating current) to regulate the amount of electricity that flows to the light source. The primary advantage of TRIAC dimming is that it is a physical dimming technique that is compatible with most types of light sources. However, Lutron Caseta dimmers use a different type of dimming technology called electronic low-voltage (ELV) dimming.
ELV dimming is a digital dimming technique that uses a microprocessor to control the amount of electricity that flows to the light source. ELV dimming is particularly well-suited for LED lights, which require a very low amount of current to operate. Lutron Caseta dimmers are designed to work with a wide range of load types, including LED, halogen, and incandescent bulbs.
One of the advantages of Lutron Caseta dimmers is that they are very easy to install. They do not require a neutral wire, which makes them an ideal choice for retrofit applications. Lutron Caseta dimmers also support multi-location dimming, which means that you can control the same light from multiple locations using Pico remotes.
When choosing the correct Lutron Caseta dimmer for your application, it is important to consider the load type, voltage/phase, minimum load, and maximum load. Lutron offers a variety of in-wall smart dimmers, including the PD-6WCL, PD-5NE, and PD-10NXD. You can find detailed specification sheets and installation guides on the Lutron website.
In conclusion, while Lutron Caseta dimmers are not TRIAC dimmers, they are still a great choice for anyone looking for a reliable and easy-to-use lighting control solution. Whether you are looking to control a wired light or fan, or you want to use smart bulbs or CFLs, Lutron Caseta has a dimmer that will meet your needs.
Does Lutron Caseta Offer ELV Dimmers?

As a smart tech enthusiast, I have been asked several times whether Lutron Caseta offers ELV dimmers. The answer is yes, Lutron Caseta does offer some ELV dimmers such as the Caseta PD-5NE-WH that can control your home’s ELV lighting.
Lutron Caseta offers a wide range of dimmers, including some that are compatible with Hue bulbs. However, if you need a different type of dimmer switch, there are several other brands to consider.
When it comes to voltage, it’s important to note that ELV stands for electronic low-voltage. ELV lighting systems use transformers to reduce the voltage supplied to the light fixtures. This type of lighting is often used in modern homes because it provides a more precise and consistent level of lighting.
Lutron Caseta has a range of smart features that make it an excellent choice for smart lighting control. You can control your lights using the Lutron app, voice command, or a smart remote. Additionally, the advanced installation guide provided by Lutron makes it easy to install and set up your ELV dimmer switch.
If you’re looking for an alternative smart switch, you can check out the Diva product line from Lutron. The Diva smart dimmer doesn’t require a neutral wire and features LED+ advanced dimming technology for superior dimming of LED bulbs.
Overall, Lutron Caseta is a great choice for those looking for smart lighting control, including ELV dimmers.
Frequently Asked Questions
What is a triac dimmer?
A triac dimmer is a type of dimmer switch that uses a triac to control the amount of current flowing to a light bulb. The triac is a small electronic component that can be used to control the amount of power that is delivered to a load, such as a light bulb. Triac dimmers are commonly used in residential and commercial applications, and are known for their smooth, flicker-free dimming performance.
What is the difference between triac and ELV dimming?
Triac dimming and ELV (Electronic Low Voltage) dimming are two different methods of dimming lights. Triac dimming is typically used for incandescent, halogen, and LED bulbs that are designed to work with triac dimmers. ELV dimming is typically used for low-voltage lighting systems that use electronic transformers. The main difference between the two is that triac dimming uses phase-cutting to control the amount of power delivered to the bulb, while ELV dimming uses voltage regulation.
Does Lutron Caseta offer ELV dimmers?
Yes, Lutron Caseta offers ELV type dimmers. The Caseta Wireless ELV+ Dimmer is designed to work with electronic low-voltage lighting systems, and is capable of dimming up to 250 watts of LED and CFL bulbs, and up to 600 watts of incandescent and halogen bulbs.
What is an ELV type dimmer?
An ELV type dimmer is a type of dimmer switch that is designed to work with electronic low-voltage lighting systems. These dimmers use voltage regulation to control the amount of power delivered to the light bulbs, and are typically used in low-voltage lighting systems that use electronic transformers.
Which dimmers are triac?
Triac dimmers are designed to work with incandescent, halogen, and LED bulbs that are designed to work with triac dimmers. Some examples of triac dimmers include the Lutron Caseta Wireless Smart Dimmer, the Leviton Decora Smart Wi-Fi Dimmer, and the Philips Hue Dimmer Switch.
What is the part number for Lutron Caseta triac dimmer?
The part number for the Lutron Caseta triac dimmer is PD-6WCL. This dimmer is designed to work with incandescent, halogen, and LED bulbs that are designed to work with triac dimmers, and is capable of dimming up to 150 watts of LED and CFL bulbs, and up to 600 watts of incandescent and halogen bulbs.
