What is Ceiling COB Downlight wattage?The wattage of a light generally is the indicator of how much energy the light will use. As energy saving lighting is all about reducing the wattage used in a light fitting, you can use the wattage of a light to check its energy efficiency. The wattage of a light does not necessarily accurately indicate the light output, the 'Lumens’ will show this (see definition below). E.g. A low watt LED globe might maintain a similar light output as a higher watt halogen globe.  2. What is Fixed LED COB downlight and Adjustable(Gimbal) Ceiling COB Downlight?  Fixed downlights have a fixed centre. The lamp is usually fixed within the holder either by using a spring clip or by a twist lock mechanism.  A gimbal downlight has instead of a fixed centre, a centre fitting that can be tilted allowing adjustment of the spotlight beam. These can be an advantage if you want to direct the light slightly towards a certain area, painting or workspace.
