So, it is advised to get an LED light that has surge protection. This will not only impact the ongoing match but will damage your reputation as well. Just imagine your LED lighting gets damaged because of a surge. Surge protection is a crucial factor in LED lights as a sudden increase in electricity might damage the LED light or cause failure. The first thing in basketball court lighting is surge protection and IP rating. We have highlighted the lighting design for outdoor commercial basketball courts.

Whether you have a commercial, residential, recreational, or professional basketball court, make sure the lighting design is in accordance with the standard. If you have a very specific need, we recommend further research.When it comes to installing LED lighting in the basketball court, every type of court has different requirements. The IESNA Lighting Handbook has pages and pages of various categories. Please keep in mind that this chart is not comprehensive. In general, low contrast and detailed tasks require more light while high contrast and less detailed tasks require less light. The required light levels are indicated in a range because different tasks, even in the same space, require different amounts of light. The LPD levels should continue to drop with subsequent codes and as LED lighting becomes more energy efficient.
The US General Services Administration provides lighting levels and LPDs for US Government buildings, which can be used as a guide for other types of buildings. Check your local jurisdiction for other or more stringent requirements.
The table below provides recommended light levels from the IESNA Lighting Handbook and LPD levels from the IECC 2021 (using the Space-By-Space Method for calculations). For instance, a utility incentive program may require a 15% (or more) improvement over the baseline LPD in order to receive a lower electricity rate. Many utility incentive programs require the design team to improve upon the lighting power density baseline required by local codes. The second way is to calculate the LPD based on each specific room and is called the Space-by-Space method - this method is much more accurate and may result in a lower LPD number, which is helpful when applying for utility incentives.

The first way is to use an LPD that applies to the full building based on the type of building (school, museum, office, etc.) - this method is very basic and is called the Building Area Method. There are two ways to calculate the lighting power density. Always make sure to check your local codes before establishing LPD criteria for your project. Please keep in mind that certain cities or states may have codes that require LPDs to be a certain percentage BELOW the IECC and that different jurisdictions use different versions of the code.

The values listed below for LPD come from the 2021 version of the International Energy Conservation Code (IECC 2021) and are based on the Space-By-Space method of calculation. Lighting power density is established by local and international codes. – essentially, if the component or device is involved in lighting, it must be included in the calculation. Included in the watt measurement is all power consumed by light fixtures, ballasts, controls, transformers, etc. In the United States, LPD is measured in watts per square foot. Lighting power density is the amount of power used by lighting per unit of building area. The lighting levels listed below come from the Handbook as well as various other lighting references. The most cited reference for lighting levels is the IESNA Lighting Handbook, which is published by the Illuminating Engineering Society. Detailed tasks like drafting require more light, while general tasks like walking can be accomplished with less light. We need to provide enough light to allow people to accomplish see their tasks, but not so much light that it is hard to see the tasks – over lighting is just as bad as under lighting.
