Lutron Caseta is well known for its high-quality smart lighting switches. Being able to dim your lights is a bonus, but many bulbs, even though they work with your switch, can buzz, flicker, and vibrate, leaving you with an unpleasant experience. There are many manufacturers of bulbs and just as many standards. Thankfully, smart switch companies like Lutron regularly test bulbs to provide you with the latest research, helping you find the right bulbs for your home lighting system.

There are many standards that bulb manufacturers need to meet to produce bulbs. However, these standards can vary and leave some bulbs underperforming and providing compatibility issues with certain switches and systems. Below, we will look at some of the most common bulbs on the market and narrow down which ones will work best with your Lutron Caseta.

What Light Bulbs Work with Lutron Caseta?

Companies like Lutron Caseta are always testing bulbs to ensure that your experience is satisfactory. With that said, to find the best bulbs for Lutron Caseta, visit the manufacturer’s website and use their compatibility tool to help find one that tested well with their smart dimming switch. Simply choose your dimmer’s model.  

However, when you open their compatibility tool to search for a bulb that works well with your dimmer switch, you will first need to accept a disclaimer before continuing. In part, the disclaimer mentions that “Bulb manufacturers can modify their bulbs at any time, without notice to Lutron.”

This can leave a smart switch owner frustrated. Finding a compatible bulb, then finding that the bulb tested well by Lutron, only to have been changed, affecting performance, can be frustrating.

Let us look at some of the bulb types that can be used with your smart switch and considerations when using them:

Halogen BulbsProviding a lighting experience closest to incandescent with higher efficiency, they deliver a quality dimming experience without the negative experience found with CFL bulbs.
Screw-in LED BulbsLED bulbs provide the highest efficiency for bulbs of the screw-in type. However, manufacturing standards vary greatly, and dimming performance can vary widely.
