The first step to Maximize LED Retrofits is to understand the problem in depth.
To understand your problem you should ask yourself questions like What are you looking for? Is your priority energy saving, or are other problems that the new installation needs to solve too?

The General Services Administration or known as GSA recommend asking questions to help define your needs:

Is the space already overlit?
What will be the current and future lighting needs?
How long will you plan to occupy the space?
Do you want to incorporate sensors into fixtures?
What control capabilities are you looking for?

The next step is Understanding Unique Requirements of each space,Each Space included in the retrofit light project will have its own requirements based on the type of work done beforehand in that space. Getting Creative with Existing Infrastructure means to acknowledge the already exsiting lights and find the suitable ones for that the particular space.Lastly, It is better to Plan for Replacements beforehand.
No matter the rated lifetime on the new lighting, you’ll still have to replace it at some point. The lifetime refers to how long it will take the lighting to degrade by 30%, a level that building occupants may fail to even notice.
