More Information
Summary:There is provided a lighting device which emits light with an efficacy of at least 60 lumens per watt. The lighting device comprises at least one solid state light emitter, e.g., one or more light emitting diodes, and optionally further includes one or more lumiphor. In some embodiments, the output light is of a brightness of at least 300 lumens. In some embodiments, the output light has a CRI Ra of at least 90. Also, a method of lighting, comprising supplying electricity to a lighting device which emits light with an efficacy of at least 60 lumens per watt.
