Internal or external LED drivers are devices that regulate the power going into a single or string of LEDs.

However, some LEDs are ballast compatible. This classification shows their compatibility.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"type-a\">Type A<\/h3>\n\n\n<p>Type A LED fixtures can work with existing fluorescent ballasts because their drivers are ballast compatible. LED tube light manufacturers like Phillips, GE, OSI, and Green Creative have built such tubes and listed the number of compatible ballasts for their products.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"type-b\">Type B<\/h3>\n\n\n<p>These lamps can handle the line voltage (110V) directly. Therefore, they require a ballast bypass with no external driver. Usually, they have an integrated driver inside the tube to power and control the LEDs. Such systems are becoming popular because they eliminate the external driver or ballast failure issue. However, they have safety concerns and can have fewer incentives from local power utility companies.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"type-c\">Type C<\/h3>\n\n\n<p>Type C tubes are not ballast-compatible and don&#8217;t have internal drivers. Instead, they need external direct wire drivers. Therefore, they require high expertise to install because of the ballast removal and driver installation. This complex installation translates to expensive labor costs. However, the tubes have a long lifespan (can last up to 70,000 hours), and you can get incentives from your local utility company to offset the installation costs.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/10-15.jpg\" alt=\"Fluorescent light replacement (note the ballast)\" class=\"wp-image-1085\" srcset=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/10-15.jpg 1000w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/10-15-300x200.jpg 300w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/10-15-768x512.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>Fluorescent light replacement (note the ballast)<\/em><\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"ballast-vs-direct-wire-led-tube-which-type-is-better\">Ballast vs. Direct Wire LED Tube: Which Type is Better?<\/h2>\n\n\n<p>Ballast-compatible or direct-connect LED tubes are easier to install because you don&#8217;t have to remove the ballast.<\/p>\n\n\n\n<p>However, ballasts fail at some point. Some do not last as long as LEDs. You will have to replace the device when it burns out to get the LED tube to work again.<\/p>\n\n\n\n<p>Not only will you incur labor costs, but you must buy a new ballast. Therefore, you will incur higher costs and spend more time during this repair process.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"429\" src=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/11-7.jpg\" alt=\"A burned-out ballast\" class=\"wp-image-1084\" srcset=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/11-7.jpg 1000w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/11-7-300x129.jpg 300w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/11-7-768x329.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>A burned-out ballast<\/em><\/p>\n\n\n\n<p>On the other hand, direct wire LED tubes are difficult to install at first because you must remove or bypass the ballast. As stated earlier, this installation can be expensive if you have to hire someone to do the job.<\/p>\n\n\n\n<p>However, eliminating the ballast from the equation means the LEDs will never go off due to a ballast failure. Therefore, you won&#8217;t have to spend time or money to replace the component later.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"wrap-up\">Wrap Up<\/h2>\n\n\n<p>In conclusion, LED ballasts could refer to LED drivers or fluorescent ballasts compatible with LED tubes. But the word usually refers to the latter because LED drivers are technically and functionally different. We hope this article has been insightful.
