At LED Lighting Supply we don’t always recommend replacing fixtures, sometimes the best course of action is to use a retrofit kit. A retrofit kit doesn’t replace the metal halide fixture. Instead it converts the fixture to LED and its as simple to do as if you were replacing the bulbs and ballast.


This customer contacted us at LED Lighting Supply to upgrade their parking lot fixtures. They wanted to go to energy efficient LED Parking Lot Fixtures. They were unsure if the retrofit kit would fit their specific metal halide fixture. Our Lighting Specialists helped choose the best kit for their needs. This assured it would be the correct retrofit kit for this project.

How Much Does Lighting Cost?

Converting to LED may not be as expensive as an online search may show but it can be overwhelming. A quick search can show hundreds of options and solutions, even for lighting an indoor space. On the web LED fixtures range anywhere from $200.00 to $1,000.00. Due to this it can be confusing to determine what’s a good quality fixture that’s right for the job. Yet there is sometimes a cheaper option, if it is right for the project, and that is LED retrofit kits. Retrofit kits utilize the existing fixture and convert it to LED.


Unlike other product selections, helping a customer choose a retrofit kit can come with unique challenges. Instead of choosing a brand new fixture we are working within the confides of an existing one. Our retrofit kits will fit in most fixtures. We don’t recommend using this in fixtures that utilized low pressure sodium bulbs (SOX).

I wasn’t sure if the retrofit “shoebox” kit was going to fit my boxes and was reassured by Joe that the kit provided everything needed. I was pleasantly surprised that several options and multiple brackets were supplied in the kit. It was relatively simple to install and the lighting is fantastic. I couldn’t be more pleased!
