IDAS Filter with LED street Lights?

[BlueAstra]

I have an IDAS P2 filter that I bought a few years ago to combat light pollution in my suburban area when I do astrophotography. At the time most of the street lights were Sodium/Mercury types and the filter worked well. However, all my local streetlights have now been converted to LED types, and I'm wondering if the IDAS filter is still relevant. Any thoughts?

There is a newer version of that filter, the LPS D2, that also filters some of the wavelengths of the LED lamps. It's more difficult to block than sodium or mercury lamps, though, and since it's more agressive, it might filter what you're trying to photograph as well.
