Frequently Asked Questions

What Are LED Strip Light Retrofit Kits?

LED Strip Light Retrofit Kits are the ideal solution to convert outdated fluorescent strip fixtures into energy-efficient, architectural grade, LED fixtures. You can expect energy savings, as well as reduced maintenance costs. Here are some example light fixtures where LED strip light retrofit kits can be used.

Where are LED Strip Light Retrofit Kits Used?

Typical applications for strip fixtures include retail environments, offices, and classrooms. LED strip light retrofit kits are the perfect solution to convert a strip fixture from T12 to T8 or T5 and upgrade it to a more energy efficient option. T8 and T5 lamps have more color choices and longer lamp life than older options which makes them an ideal choice for a wide range of settings and applications, including commercial and residential purposes.

What are the Benefits of LED Strip Light Retrofit Kits?

  • Saves money. Older T12 lamps tend to burn up at a faster rate than T8 or T5 which can eat up your lighting budget. Retrofitting is also a more affordable solution compared to the cost of completely overhauling the set up with an entirely new fixture. This option allows you to keep the same fixture and housings while just changing the internal design with the right hardware and kits.
  • Easier than a new install. A new installation of a fixture is more intensive in both time and effort than simply retrofitting the existing fixture. In fact, you can easily complete this activity in a matter of minutes if you have performed a retrofit before.
  • Upgrades to a more efficient solution. While the option of retrofitting a T12 to a T8 or T5 is a more efficient solution, you also have an option of converting from fluorescent tube lighting in these sizes to LED tubes in select products. This gives you an even better efficiency in terms of lumens produced per watt consumed over fluorescent options.
  • Offers more versatility in certain aspects. T5 and T8 offer more options for color temperature over older T12 tubes. They also offer better color rendering indexes which makes them ideal for a range of settings.
