Frequently Asked Questions

We asked our customers questions they had about metal halide LED retrofit kits. Here are the answers to our most common questions call (888) 423-3191 to speak with a lighting expert.

Look at our case study of a successful retrofit installation using these retrofit kits.


What Is a Metal Halide to LED Conversion Kit?

A metal halide LED retrofit kit contains an LED head, driver, and mounting hardware. It’s designed to replace a metal-halide bulb and ballast inside a HID fixture. It can also replace high-pressure sodium (HPS) bulbs and other HID bulbs.

These kits can fit into many standard indoor and outdoor fixtures including: shoebox lights, wall packs, flood lights, uplight fixtures and many indoor fixtures. Like most LED Lights, led retrofit kits are energy efficient, have a longer lifespan than HID Lights and achieve full brightness almost instantly.

How Do You Retrofit HID / High Pressure Sodium / Metal Halide to LED?

The process is quite simple. It is the same process of replacing metal halide bulbs and ballasts inside your fixture. The major difference is that it’s an LED bulb, and you replaced the ballast with an LED driver.

Do I Need to Move the Fixtures Reflector?

The reflector is not needed, as all the LED light is directional. In fact, it’s required to remove it to increase the interior cavity space of the fixture. It creates more available cooling.

Do Your Metal Halide (MH) LED Retrofit Kits Screw into the Mogul Base?

Our kits do not have a screw-in adapter. In fact, using the existing mogul base is a bad idea. We recommend using our LED retrofit kits. They are more powerful, provide more light, produce more savings, and last longer. It’s far safer and more reliable to remove the base and use the mounting hardware we include.

How Reliable Are LED Retrofit Kits Versus New Fixtures?

The retrofit kits we sell are all UL/ETL listed, DLC listed, and carry a 5 or 10-year warranty. The only things our warranty does not cover are Acts of God, improper installation, and having a leaky outdoor fixture.

What Are the Best Applications for Metal-Halide Retrofit Kits?

If you have an expensive fixture that’s in good condition. Or you can bypass permitting by not having to replace the existing fixture.

How Do You Install a Metal Halide to LED Conversion Kit?

Any qualified electrician can easily install a metal halides conversion kit. It’s about as difficult as a bulb and ballast replacement. Any electrician familiar with HID fixtures can replace the internal components. There are only two extra steps required.

Remove the reflector
Remove the mogul base
Install the head mounting hardware

How Long Does It Take to Install Retrofit Kits?

Electricians who are familiar with the kits can do 2 to 3 per hour. If you have never used our kits, expect the first one to take 30 minutes to 1 hour. By then you will have figured out the correct mounting configuration.

Then it’s a matter of repeating it from fixture to fixture. Many of our electricians with a 2-man crew will have the electrician on the ground setting up the next kit. The electrician in the boom lift would be the one installing it.
