LED HID Retrofit Kits FAQ

1. What is a LED retrofit kit for HID Fixtures?

A LED Retrofit Kit for HID consists of a head, driver and mounting arm. It replaces the HID (Metal Halide or HPS) bulb and ballast made so you keep your original fixture.

2. Is it difficult to install a HID to LED Retrofit Kit?

If you have limited experience with wiring lighting fixtures, it may be difficult. If you are a professional electrician, this is as simple as a bulb and ballast replacement.

The process is simple. It consists of replacing the existing bulb, ballast, socket and brackets with the LED kit. Remove the reflector. The kit bolts to the fixture using the same mounting holes used to attach the socket. The driver installs where the ballast was. We recommend to bring in a licensed electrician to ensure the proper installation.

3. Will a normal fixture lose its UL or ETL certification after it is retro fitted with LED?

It should not, as long as you follow all the instructions associated with the product. Our products have the UL1598C retrofit standard, which is a bulb replacement standard. UL and ETL understand the purpose of the HID Retrofit Kits is to convert the existing fixture to LED. It replaces the ballast with the LED driver and the bulb with the LED Head. The certification process includes testing the Retrofit Kits inside a fixture.

4. Why would you retrofit versus buy a new fixture?

There are times where you have or want to use the existing fixtures. In other circumstances, replacement is OK. Local governments might mandate wiring upgrades if you install new fixtures.

Retrofitting may allow you to bypass code upgrades by utilizing the existing fixture. You may also have a significant investment in a particular architectural fixture.  Replacement is not an option.

5. How much energy can I expect to save?

You should expect at a least 70% energy savings. This depends on the what you are replacing and what LED model you choose. Adding controls will help you save more. Adding motion sensors to a parking lot fixtures will allow you to dim the light when there is no activity. When the fixture detects motion, the fixture can switch to 100% levels again.

6. How long do your HID to LED Retrofit Kits last?

HID LED Kits tested for 100,000 (L70) hours of use, in normal operating conditions. This is about 6X longer than metal halide, HPS or other similar lighting technologies.

L70 is a standard that defines how many hours it will take for the light to reach 70% of initial lumens. Compared to HID bulbs with a lifespan between 12,000 to 20,000 hours, the L50 is at bulb half-life.

7. What voltages are available?

We offer 2 power supply options. One for 100V-277V and the second for 277V-480V.

8. How long is the warranty?

Our heads carry warranties for 10 years, the drivers at 5 years. If you follow installation instructions, you should not have any problems.

9. What is the difference between DLC Standard Qualified and DLC Premium Qualified?

In a nutshell, it is about efficiency and savings. DLC Premium Qualified is for high efficiency LED products. This means that these lights are brighter and use less energy.

For example, a LED Light at 150 lumens/watt creates 15,000 lumens while using 100 watts. A LED light at 97 lumens/watt only creates 9700 lumens using the same 100 watts.

Producing 9700 lumens with the 150 lumens/watt product would only need 64 watts.

10. So what is all included in a retrofit box?

Our kits contain a LED Head, a driver, and many installation adapters. Our DLC Approved unit does not include a socket adapter. We do not think they are safe and they will cause the fixture's socket to fail. We recommend you stay away from kits that use a socket adapter as its not a long term solution.

LED Controls

Our Retrofit Kits are Controls Ready!

Our LED HID Retrofit Kits can switch on and off without affecting their lifespans. This allows for the use of motion sensors , photocells, timers or other controls.

0-10V Dimming option available. This works in conjunction with motion sensors. Our lights adjust light output from 10% to 100% to save you even more money.

Using Control with LED Retrofit Kits for HID fixtures

Controls such as motion sensors can either turn off the fixture or dim it. If your goal is to dim the light output, make sure you order a dimmable LED Driver.

LED Voltage

High Voltage LED Drivers are available

Are you trying to retrofit fixtures that are 277V? 347V? 480V?

We have solutions that cover these higher voltage installations. Constant current drivers can handle everything from 100V to 277V.

Higher voltage drivers can handle 377V to 480V. We can handle single or 3-phase power as well. Talk to our sales engineers and we can get your lighting situation taken care of.

480V High Voltage?

The standard driver with our HID Retrofit Kits are 100V to 277V. Tell our sales engineer that you need a high voltage solution so we can ship you our high voltage drivers.

Mogul Adapter is bad image

Our LED HID Retrofit Kits don't come with a Mogul Socket Adapter. This is a good thing!

Many old fixtures have an E39 socket or mogul base. They engineers designed then to hold a 400W and 1000W HID bulb, not retrofit kits that weigh 5X more.

Imagine a shoebox fixture in an outdoor application, 20 ft in the air on a windy day. The fixture will sway, stress the mogul socket and eventually fail. The retrofit kit will fall to the glass of the fixture.

MyLEDLightingGuide Kits include mounting adapters to replace the mogul socket. This provides a secure, fail safe mount for the LED Head. Our installation procedure includes the removal of the mogul socket.

DesignLights Consortium DLC Premium Qualifications only apply to direct mount kits. So if you want a safer mounting option and a higher rebate, avoid using a mogul base adapter.

What are the steps to install a retrofit kit inside a metal halide or HPS fixture?

Installation of a HID retrofit kit - a simple and fast process

A typical installation is around 15-20 minutes per fixture

• Turn off the Power to the existing fixture, and open the fixture up to expose the bulb and ballast.
• Remove the bulb, ballast and socket from the fixture.
• Remove the reflector - only if the reflector is not part of the fixture's watertight seal.
• Install the LED driver in the location of the old HID Ballast. Wire the driver to the same wires that powered the ballast.
• Configure the mounting arm for your fixture. Install the arm to the fixture and then install the LED Head to the mounting arm.
• Connect the wires of the LED Head to the wires of the LED Driver.
• Position and aim the LED Head to optimize light distribution.
• Remove the protective plastic cover from the LED head.
• Clean the glass of the fixture (if required) and close the fixture.
• Turn the power back on.

MyLEDLightingGuide LED HID Retrofit Kits are efficient!


Lumens Per Watt Image

Because Efficacy and Lumens per Watt Matter when you want to replace Metal Halide!

MyLEDLightingGuide has one of the most efficient commercial LED HID Retrofit Kits available. Looking for a 400 watt Metal Halide bulb upgrade? Our 100W LED conversion retrofit produces 15,550 lumens. That's 155 lumens per watt.

Why does this matter? Consider other competitive options available. One such product is a 340W retrofit unit producing 39000 lumens @ 114.7 lumens per watt. In comparison, our 350W HID retrofit kit produces 50,750 lumens @ 145 lumens per watt. Even our 280W hid unit produces more lumens (43,120) than their 340W unit. We produce more light and consume 60W less energy. Converting to LED saves money by using less electricity. Why would you choose old and outdated LED technology?

So lumens is one thing, but let's calculate this another way.


You want to reduce your lighting bill (or grab hold of the other benefits LED has to offer). It's all about producing the right amount of light and doing it using the least amount of energy. If you have outdoor area lights and are looking to retrofit them, you can choose our product at 100W / 15,550 lumens. Or you can choose their product at 135W / 13,164 lumens. They both have 10-year warranties.

Their product is DLC Standard. Ours kits are DLC Premium Qualified. For every light you replace with our Kit instead of theirs, you will burn 35 less watts and produce 2,386 more lumens.

Converting HID bulbs to energy efficient Commercial Lighting Retrofits will save you money. So before you buy, you need to shop and determine which DLC Qualified LED Retrofit kit will save you the most.


"Never buy a retrofit bulb, lamp or solution based on watts. Determine the lumens you need and get the most efficient retrofit that uses the least amount of energy."
