Lutron brand TTCL-100H plug-in dimmer module that works with our dimmable bulbs.
*This will not work with any of our 14w or 24w bulbs, and can damage them if you try!"
You should use a separate dimmer for each bulb. When you are adjusting the brightness, you may notice some flickering. You may need to slightly adjust the brightness a bit until the flickering goes stops. Setting the brightness too low will cause flickering and can damage the bulb over time.
