FAQ

1. What's IP Ratings ? (Ingress Protection)

A two-digit number established by the International Electro Technical Commission, is used to provide an Ingress Protection rating to a piece of electronic equipment or to an enclosure for electronic equipment.

The protection class after EN60529 are indicated by short symbols that consist of the two code letters IP and a code numeral for the amount of the protection.

Example: IP65 (NEMA 4)
The two digits represent different forms of environmental influence:
 • The first digit represents protection against ingress of solid objects.
 • The second digit represents protection against ingress of liquids.

The larger the value of each digit, the greater the protection. As an example, a product rated IP54 would be better protected against environmental factors than another similar product rated as IP42.

IP TABLE:

IP.. First digit:
Ingress of solid objects
Second digit:
Ingress of liquids
0 No protection No protection
1 Protected against solid objects over 50mm e.g. hands, large tools. Protected against vertically falling drops of water or condensation.
2 Protected against solid objects over 12.5mm e.g. hands, large tools. Protected against falling drops of water, if the case is disposed up to 15 from vertical.
3 Protected against solid objects over 2.5mm e.g. wire, small tools. Protected against sprays of water from any direction, even if the case is disposed up to 60from vertical.
4 Protected against solid objects over 1.0mm e.g. wires. Protected against splash water from any direction.
5 Limited protection against dust ingress.
(no harmful deposit)
Protected against low pressure water jets from any direction. Limited ingress permitted.
6 Totally protected against dust ingress. Protected against high pressure water jets from any direction. Limited ingress permitted.
7 N/A Protected against short periods of immersion in water.
8 N/A Protected against long, durable periods of immersion in water.

2. What's LED light Color Temperature ?

Shades of white light are measured in degrees Kelvin, where lower degrees indicate yellower light and higher degrees indicate whiter or bluish white light. Soft White (2700° Kelvin) is the warmest option that most closely approximates a standard incandescent bulb. It is most often used in areas like living rooms. Bright White (3500° - 4100° Kelvin) is a whiter light than soft white and is most often selected for kitchens and bathrooms or work spaces. Daylight (6000° - 6500° Kelvin) is recommended for reading areas or for use in craft rooms and is a more bluish white that most closely approximates an outdoor overcast sky.


3. What's LED light LUX ?

Lux is the international(SL)unit of illuminance, a measure of light arriving at a surface, 1 lumen per square foot equals 1 footcandle, while 1 lumen per square meter equals 1 lux.
[lux = lumen/m2]

                                                                      
4. What's Light Bulb Beam Angle ?

Light Bulb Beam Angle
Common terms in selecting a light bulb are 'flood' light or 'spot' light. These are designations of beam angle. The beam angle is the degree of width that light emanates from a light source. Specifically: The angle between those points on opposite sides of the beam axis where the intensity drops to 50% of maximum.
Typically a narrow beam angle is a 'spot' of light and a broader beam angle 'floods' an area with light, called a flood light. There are a number of much more specific designations of beam angle. They are not used consistently between all the light bulb manufacturers, but several use this general terminology:
