LED street lights

Historically, street lights were wired in series - up to 40 lights in a string at 50V per light, requiring 2kV or more. Most street lights run on typical neighborhood power and the people living near them pay the electric bill.

It looks like we need to develop at least two more, maybe three, prototypes at considerable effort and expense. We just want to make sure we are not wasting time and money here.

Our questions are:

Of the above voltages, are they all used for street lighting

Do we really need to accomodate 208, 240 and 277?

We know we need a 110V system and a 480V system because that's what we find around town. How about those in the middle?

A Switch Mode Power Supply (SMPS) is not feasible because it adds cost, space, heat, power consumption, etc. to the device. Requirements on the project include the ability to adapt to all existing AC systems without being cost-prohibitive. 

Thanks in advance. This looks like a great venue.

Look at other manufactures similar products and notice how many voltages they will provide them in.

In general we want to run the fixtures at the highest available voltage for cost reasons. 

If 120 is available that usually means 208 or 240 is available and with the distances involved with outdoor lighting projects I will want to use the highest voltage available. If your product is only available in 120 volt I would pass it by and find a suitable product in the voltage I want.

In addition to that you take yourself out of retrofit projects if your product does not match the voltage of the fixture you are replacing.
