I'm new to CPF as I normally was able to gather my lighting needs at retail, but things have changed. I can't find a any source of quality and dependable high output infrared lights which lead me here. I'm not a fan of combo white and ir lights like the V2 from surefire. I want to make a simple high output only clickie or momentary style light in a compact form factor. Think e2d with kx2c, but IR. Plan is to have a real thrower with minimal spill like the kx2c does in white and hopefully have a usable light out to 400-800m with Gen III NV. I'm wondering if anyone here has tried something similar with the surefire e-series heads? What are your thoughts? P.S. Is there a database that lists the model of led in surefire's offerings?
