LED Retrofit Kits

Frequently Asked Questions

There’s a lot of questions to consider before you buy LED Retrofit Kits. Scroll below to find answers to our most common questions or call (888) 423-3191 and we’ll do our best to assist you.


What Are LED Retrofit Kits?

LED retrofit kits are designed to upgrade existing HID and fluorescent lighting without replacing the fixture. Depending on the type and style of the kit, LED retrofit kits replace the fixture’s bulb and ballast with an equivalent, if not better, LED light source.

What Are the Different Types of LED Retrofit Kits?

There are many, but the two most common kits replace metal halide bulbs and fluorescent tubes. We also have different sizes and mounting options, depending on the specific fixture.

Where Does It Make Sense to Use Retrofit Kits?

There are many reasons to use retrofit kits; the most common is an LED retrofit in an existing fixture. This is not always possible or practical; in this case, the existing fixture would need to be replaced entirely.

The fixture may be unique, expensive and hard to replace.
Changing out a fixture may require permitting or expensive engineering costs.

In these cases, retrofitting is a great option.

Retrofitting Parking Lot Fixtures with LED


What Are the Best LED Retrofit Kits?

We have several options and this depends on the fixture size, type, and wattage.

We have shoebox retrofit kits designed specifically for parking lot fixtures.
For post top lights, we offer post top retrofit bulbs and lamps.
We have a generic set of metal halide retrofit kits that fit into many different types of fixtures.
And we offer a line of linear magnetic retrofit strips designed to replace fluorescent tubes

Contact us and we can help you find the best option.

Do your metal halide retrofit kits work with photocells?

They do. In fact, if the fixture you are retrofitting already has a photocell, keep it. It will still work when you convert over to LED.

How Efficient Are Retrofit Kits?

LED retrofit kits are extremely efficient, on par with the most efficient new light fixtures. Our shoebox retrofit kits operate at 165 lumens/watt.


How Do You Install an LED Retrofit Light Kit?

We provide complete instructions, but LED retrofit kits should be thought of as bulb and ballast replacements. The kits are designed to replace the traditional bulb with a LED equivalent and ballast with an LED driver. We highly recommend you use a licensed electrician.

Do I Need a Ground Wire for an LED Retrofit?

Most LED drivers have 3 wires: line, neutral, and ground.
