55 watt CF fluorescent bulb is huge. They won't fit in a lot of regular fixtures. Keep in mind it is brighter than 150 watt incandescent.
So maybe that's it? They are designed for the huge high wattage CF bulbs?
That 55 watt was just an example to make a point.
It looks like to me is they are classifying these fixtures as energy efficient because they only take efficient bulbs. However, what I have been getting at is that there really isn't anything efficient about the fixtures themselves and it is misleading to consumers. They charge a lot of money for some of these fixtures.
Someone who might not know any better might spend a lot of money replacing fixtures when all they really have to do is change to a lower wattage bulb or an energy efficient bulb with lower wattage and the same light output.
Some of you mentioned that these fixtures would only take E.E. bulbs and this is correct. Here is some interesting reading from the Maxlite website about the new GU24 bulb for those of you who may not know. Pay paticular attention to the paragraph that talks about how you can put any GU24 bulb in any GU24 fixture and not have to worry about the wattage rating:
• THE GU24 BULB AND FIXTURE
By year-end, GU24 will be the most common type of Energy Efficient Light Bulb used in Energy Efficient fixtures. They will be the new standard of light bulb in homes and offices and will be used in all fixture categories; outdoor fixtures, ceiling fixtures, wall sconces, vanity bars, table lamps, floor lamps, hanging pendants and torchieres.
• What is it?
The GU24 Light Bulb does not have the usual screw base, but instead has two bayonets protruding from the base. These insert into matching holes in the fixture's socket, and twist to lock into place. Twist and pull, and the bulb comes right out of the socket.
• What are the benefits?
The outstanding benefit of the GU24 innovation is that any fixture with a GU24 socket can now take any bulb with a GU24 Connection. That means a fixture is not limited to the light source it was manufactured with; the wattage, and the color and the style of bulb can be changed for any bulb with a similar connection. (If more light is needed, use a higher wattage bulb. If less, use a lesser wattage bulb.)
• On Energy Star fixtures?
It is expected that the majority of Energy Efficient ENERGY STAR qualified fixtures will use the GU24 connection. They will accept either a GU24 Bulb or a two piece GU24 self-ballasted socket, which will take a pin-base lamp.
• Replacement bulbs?
Replacement bulbs will be available wherever light bulbs and fixtures are sold. MaxLite is already producing families of GU24 Bulbs and these will be available in stores, and on the web, from the MaxLite partners who are already selling MaxLite products.
