What Is a Photometric Lighting Plan?
A Photometric Lighting Plan is a software report of LED lights placed within an indoor or outdoor area. The software is capable of importing layouts, CAD diagrams and even scaled Google Maps of outdoor areas – particularly interesting when creating lighting plans for outdoor sport facilities.
The software can place the fixtures inside the plan at specific locations and heights. They can be oriented and aimed. 
The lighting plan calculates foot-candle light levels, shows how balanced the light is, and provides a comprehensive printable PDF report.

When Do I Need a Photometric Lighting Plan?
A lighting plan would be highly recommended before any lighting project is started, and before any lights are purchased. It will provide you with most of the information you need to make an informed decision.

How long does it take to prepare a lighting plan?
While complex requirements can take longer, a good rule of thumb is: 24-48hours.

What does a Lighting Plan Provide?
 It will provide a visual report of your space, and identify the fixture(s) used, the fixture locations, the foot candle measurements across the space, and how even and balanced the lighting is across the space.

What can I expect with the results of a Lighting Plan?
The results of each plan is specific to the particular space dimensions and fixture model, wattage, lumens, optic used, color temperature and mounting angle used. 
You should not expect the same lighting results indicated by the lighting plan if the fixture is swapped out for another fixture.

Are those Lighting Plan &Dialux Simulation Free?
We offer free lighting plans for contractors along with commercial & industrial end users.
We are typically unable to provide free lighting plans to architects, as the full project plans are usually unknown at this early stage and require extensive non-design work. 

What software is usually used for lighting Plan & Lighting Simulation?
Nomally,we use DIALUX.
In addition to this, we also use AIG 32,RELUX,LIGHTSCAPE Run the Simulation for customers.

What the Information need to Provide For the Lighting Plan & Lighting Simulation?
Generally, we require you to provide your basic contact information.
There are also the length and width of the venue, the position and number of light poles, the height of installation, the average illuminance and so on. 

The more detailed information is provided as possible, the more accurate the simulation & lighting Plan will be. 

Lighting Terms
Lumen –  A lumen is a unit of light. By itself it’s useless, but it becomes useful when it defines the collective lumens produced by 1 fixture or bulb. It is the amount of visible light that a fixture emits.

Lux (lux, legal symbol lx) -a unit of illuminance. An object that is uniformly illuminated by light has a luminous flux of 1 lumen on an area of 1 square meter, and its illuminance is 1 lux. 

Foot Candle –  A foot-candle is a measurement of light at a specific location, and 1 to many lights can contribute to the specific foot candle reading at that location. Foot candles (or its equivalent LUX) are the requirement that most are looking for when they describe a light level for a project, facility, or location.

One footcandle is equal to approximately 10.76 lux. In practical applications, as when measuring room illumination, it is often not needed to measure illuminance more accurately than ±10 %, it is sufficient to think of one foot-candle as about ten lux.

Beam Angle -The beam angle of a lamp is the angle at which the light is distributed or emitted. 
This can be done with additional optics, or as is the case with LEDs, by engineering the light in a specific way. LEDs have an extremely large range of available beam angles. 

Generally speaking, the smaller the angle, the farther the illumination distance is. The bigger the angle, the wider the coverage.

Note: We buy the Lights Lux,Not buy the Wattage and Lumen.

           Reita Lights is 2-5Times Higher Lux Than other Nomal LED Lights under the same conditions.
