For local lighting, not only need to compare the luminous flux and power, more needs to focus on measuring the light distribution characteristics. The use of the Bonneville Power headquarters hall projection lamp, compared to the PAR38 halogen lamps, fluorescent lamps greatly reduces the power loss, but not meeting the target light distribution effect. LED street light bulb is very good solution to this problem, because of its small light divergence angle, making the art lighting effects than the surrounding wall is much better. Considering the selection of lamps, such as launch angle and center emission optical density and other factors, should be luminous flux and power together as examine the indicators.
LED replacement lamps for efficient lighting (CFL) phase, may not really reflect its value faster lamps, but this is not a replacement key. The economic rate of return is only partially depends on the difference between the current system and replacement system power. Although fluorescent energy saving, but the LED street light bulb needs more time to reflect its economic value. CFL can not focus light in the art, it is not suitable for this application.
Compared to fluorescent lamps, LED lights can improve the color quality and power efficiency. Purchase products, check the technical specifications of the led high bay products (such as CCT, CRI, etc.) to ensure that the product is suitable for the application of the basic requirements. However, the color index is sometimes the human eye to see the same information and can not effectively convey the quality of color illuminate. Hence the need for an entity model to the specific analysis and evaluation.
