Woops... i meant High Pressure Sodium, what could i do for that?

Yes absolutely I understand, I just don't know where to begin to create a filter. I have spent a lot of time researching it but always return to square one Yes absolutely I understand, I just don't know where to begin to create a filter.

Thanks guys sorry i was not more specific I am trying to build a filter for a low pressure sodium bulb, i do not want to just purchase something from a manufacturer. Last year we were able to determine the lengths of certain organisms migrations and how different sources of light pollution effected them, this year the goal is to come up with a solution.

Hi i am doing a high school research project. Last year we worked on determining what affect certain lighting had on the migration of organisms. We determined which light sources were most damaging and which would be most easily filtered. This year we are trying to work on a solution, i am having trouble coming up with a budget... is their a way to coat glass to filter out certain wavelengths? I have done a lot of research with little success, and i always seem to end up with an article about electron guns to apply thin film layers to the material. Any suggestions as to what i can do for this? i am truly stuck... Thanks
