No problem, merely a misunderstanding. That's actually the point of that product (the 'g' in the model number was the clue). This is their "eco-dim" line of products, and its specifically designed to not let the lights go over 85% light level. Its a means of using the dimmer to help guarantee energy savings and lamp life extension.

If this bothers you, then I would return it and grab one that doesn't have the "g" in the model number.
