Are Lutron Fluorescent Light Ballasts Obsolete? (Alternative Solutions)

Nothing lasts forever, and that includes fluorescent ballasts. While yours may be working fine right now, the truth is that Lutron fluorescent ballasts are obsolete. Therefore, it’s a good idea to replace your ballasts before it’s too late.

Many dimmable fluorescent ballasts wire differently than an LED, so a replacement or conversion MAY require you to rewire or rip out the entire infrastructure so you can do it over. This can be a slow and costly process.

Another option is to leverage a C-Flex kit to upgrade your lamps. It’s an easier electrical process that’s plug and play, all within the bounds of your fixture.
