> the customer should be smart enough
Oh how I wish that were true in all cases :)
Integral occupancy sensors are usually an easy sell, like you said the energy savings usually cover the added cost of the sensor and relay, given that most LED pole heads draw anywhere from 50w to 150w. It also simplifies installation and maintenance since you don’t need to switch a whole line of poles with a single occ sensor and contactor.
The more esoteric options are usually a harder sell, stuff like glare shields and non-standard optics/distribution. I see options like this selected when a commercial property borders residential property, but it’s atypical.
Photometric studies can be done to figure out what options should be selected, but the customer, engineer, and contractor are all overworked and don’t always design things the way they could (or should) be designed. I will say that wealthier areas tend to have the budgets and time to go the extra mile on stuff like this.
FWIW, one of the things I do at my day job is sell LED pole heads (and a full range of electrical services) to municipalities (and others).
Here’s an example pole head cutsheet that shows the options that can be selected for reference: https://pdmassets.azureedge.net/library/LL/documents/specshe...
