Yeah, the fact those lenses show a light transmission rate of 0% doesn't mean anything. Well, it probably means they weren't known at the time they were inputted into the database. For instance, Pink Iridium is rated at 63% if my memory serves. Of the lenses I own, Ti Clear is by far my "lightest" followed closely by Pink Iridium, HI Persimmon, Ruby Clear, and Gold Clear. You could probably get away with any of those in low light situations.
