Benefits of GU24 lamps:
The benefit of the GU24 self-ballast lamp is that any fixture with a GU24 socket can now take any GU24 regardless of wattage. 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.)
