A LED wedge base is a type of light bulb with two wires that extend upwards from the base of the bulb (rather than being pins), and the wires are pressed tightly and some are molded to the sides of the glass and when pushed straight in make contact with the socket. On glass wedge base bulbs the tip is typically narrower than the top so it wedges itself into the socket giving the light bulb a tight connection. Some wedge bulbs also have a plastic base, and once pushed deep into the socket snap in.
Wedge Base Bulbs of this type are typically used in low voltage landscape and garden lighting where a single element is used. It is also common for Wedge Base Bulbs to have dual elements, acting as both a low brightness parking or running lights and higher brightness turn signals.
When selecting a LED Wedge Base Light Bulbs it is important to select the correct lumens.
Lighting Facts CRI Consider selecting light sources (light bulbs) that have a high CRI (color rendering index) like clearly explained in the chart above. This metric though possibly changing to CQS shortly (color quality scale) is still extremely helpful in areas where the true color of an object is needed to be known.
CCT CCT (color correlated temperature) is how you pick the actual color of the light being emitted. If you are thinking this a foreign concept you probably already have been changing this in your space if you ever used a dimmer.
Lumens Lumens are a measure of brightness or more technically a unit of luminous flux emitted from a lamp in all directions. The light flux falling on a surface one square foot in area, every part of which is one foot from a point source having a luminous intensity of one candela in all directions.
