I've been provided with a light inventory for our building and so know what type of light I'm looking for (e.g. 18W F840). I've also found the Philips, GE and Sylvania LEED-EB calculators. What I can't find is any link between the two. All of them require specific product codes or product names and linking the product I'm looking for the product name is proving very frustrating.

Is there any efficient way to identify the optimal replacement products?
