I do not understand the star request for presentation. Is the lightbulb making a presentation? How dinner is served makes a presentation. However . Unless I've encountered a major problem with a lightbulb, such as exploding or blowing out in a very short period of time, I don't know how anyone can provide a helpful overview of a standard lightbulb. I do a lot of reviews on Revain, but how do you rate a famous brand lightbulb? It works great wherever I always use a 40w bulb. It takes a good time. I can't tell HOW long a consumer reporting site could do this as I would need to keep a record of how long I had "that" lightbulb on. But I think I would notice if they burned out too quickly. They take it for granted when a lightbulb or EVERYTHING is working properly, only to pay attention and notice when it isn't working properly. These lamps work as they should and as expected.
