based on LED Bulb the fluorescent lamps

 For other types of light sources can also be calculated using a similar method. However, based on  LED Bulb the fluorescent lamps, compact fluorescent lamps (CCFL), and the LED lighting device, we must be considered in the calculation of loss and isolation ballast DC - AC constant current control loss. Table 1 compares the energy efficiency of various light sources. Next, we analyze the LED-based lighting fixtures energy efficiency calculation.

Calculating the energy efficiency of LED lights

LED Module

We often see some LED manufacturers claim that further improves the LED lighting source lm / W performance. DOE's research program is to develop the commercial lighting field from the current SSL source efficiency 30lm / W up to 150lm / W or more.

  LED Flexi Strip

According to the current SSL recessed lighting Energy Star draft plan, we can calculate the use of existing components consisting of SLL overall energy efficiency of lighting devices. For slightly larger diameter 4 inches, correlated color temperature (CCT) of 3000K of the illumination device, its minimum brightness of 500lm, minimum light efficiency of 35lm / W.
