Anyone have much experience with low wattage T8 lamps? Two of our clients have been using the long life 25W variety for a year or so and are having some issues. They are a little fuzzy on the details, but I think it amounts to not being able to step dim or do master/slave ballasts (voltage issues?), or use the fixtures in cooler weather that a more robust 32W lamp could handle. Plus the cost of the 25W is significantly higher.

Any thoughts?
