LP filter for LED lights

[traveller (Bo)]

Would be interested in hearing from experienced AP peeps on the best LP filter.
I currently live 10km from Melbourne CBD, so a fair bit of light pollution. Our street lights are getting changed to the new energy efficient LED types (from the old mercury vapor type).
I currently use a Baader UHC-s http://www.company7.com/baader/options/uhc-s.html It works well but really suppresses blue reflection nebula.
I have been reading up on Orion Skyglow, IDAS LPS, CLS and the list goes on, enough to make my head spin.
So I am after some first hand user reports on the various LP filters in LED streetlight and inner city LP conditions.
My scopes and cameras on my signature, I am also refurbishing a 10" Schmidt Newtonian (f/4).
Thanks

Bo,
Bad news I'm afraid....
The spectrum of these LED lamps is pretty well continuous - no emission peaks which can be easily filtered out.
May be energy efficient for the councils but a very unwelcome source of light pollution for astronomers......

Thanks Ken,
From what I can find out, the LED streetlights are very directional so they have a tighter light "cone" than other streetlights. The nearest soon to be LED light is about 50m from my scope, what can I get away with at this distance?

Unfortunately still the same answer...direct/ indirect/ reflected (from buildings/ roadway/ haze/ clouds/ puddles) still gives a continuum spectrum, only the intensity will vary.....

Bugga!
I will stick with my UHC-s for now and wait for the lights to be replaced (due by end of this year) and see what happens.
