The cheapest way to optain a narrow band ligth source is using laser diodes properly drived, other option for a good ligth source is using an HiD lamp with some filters in this case the ligth depends strongly of the filter, although good filter are not cheap (In my case I have been using some dichroic filters that I savaged frome a "1 hour automatic film develop machine").
