1. Because of the dimensions of power, there are some difficulties and limits to luminaire, so the luminaire efficiency will be very diffirent.

2. The Efficiency of LED luminaire is high, but the LED light beam can’t be distributed to the light area averagely.

3.  Effective Visual Luminous Ratio is determined by the luminaire and color rendering index.

 4. The effective visual ratio of electrodeless lamp is low because of the power dimensions are very big.
