Electrical Terminology

Understanding Lumens and Watts:
Watts refers to the amount of electricity that a particular product is using. Lumens refers to the actual light output.  The higher the number of lumens, the brighter the light. LED's are lower wattages, therefore lower electricity cost, but sufficient lumen outputs which has made them good replacements for the traditional bulbs i.e. 50W halogen GU10/downlighters, energy savers etc.  Choose the lamp with the highest lumen output.  i.e. 50W halogen GU10's - look at anything from 5W - 7W, compare the lumen output and make your choice.

Beam Angles:
When LED's first arrived the most common beam angles for the domestic home were 24-26 degree (medium) or 36-38 degree (wide). The continuous development of LED's has improved on beam angles with 60 degree and 110 degree angles been a better choice.  It is a good idea to buy 1 or 2 and test them first as each area will require a different lamp.  If you have a small area or perhaps prefer a more precise spot light, choose a smaller beam angle.

Average Rated Life Time Hours:
In the light bulb industry, the Average rated life of any light bulb is defined by how long it takes for a percentage of the light bulbs in a test batch to fail. For instance, if 100,000 bulbs were tested and after 1000 hours, 70,000 (70%) of the bulbs had expired, this product would have an average rated life of 1000 hours at L70. There will of course have been many failures during the initial 1000 hours and likewise there would have been a number of lamps lasting well in excess of 1000 hours.

Cap's and Base's:
Light lamps/bulbs are available in a variety of Caps and Bases. Please see our list below: 
 
      B22 (Bayonet), E27 (Screw base) Used For: 
      Living room lighting, desk and bedside lamps, table lamps, security wall lights.

      E14 Used For:
      Decorative lighting, chandeliers.
 
      GU10 Used For: 
      Kitchens, track style spot lights, bathrooms and retail showrooms. Display, and directional down lighting. Also, recessed lighting. Twist and Lock,               2 connectors. 

      T8 Used For:
      Retail, Schools, Hospitals, Offices, Parking Lots. Warehouses, Public Areas. 

IP Ratings (Ingress Protection):
What is an IP Rating?
The IP (Ingress Protection) rating refers to the international measure of the degree of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures. The standard is intended to provide users with more detailed information about the product beyond terms such as "waterproof" or "splashproof".

The classification system utilises the letters IP followed by two or three digits. The first digit of the IP rating represents protection against penetration by solid objects accessing hazardous parts. The second digit indicates the degree of protection of the equipment inside the enclosure against moisture. An X in place of either digit means that either the enclosure has not been tested or that the test is not applicable.

For example, an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. IP22 or IP22X are typical minimum requirements for the design of electrical accessories for indoor use.

What does this apply to?

The IP rating should be taken into account in both outdoor and indoor environments where there is moisture or water, such as a kitchen or bathroom.  For outdoor fittings, make sure to use IP63 or higher fittings.

What is the difference between Warm White, Cool White & Daylight?

The colour of the emitted light is measured in Kelvins (K).  If you like traditional yellowish colour of a conventional lamp then Warm White(3000K) would be your ideal choice, this is the most popular choice for homes.
The Cool White Lamp(4000K) is in between the warmth of the 3000k and the bright white of the 6500K.   If you prefer a cleaner, brighter feel, then choose Daylight (6000K/6500K)

Below is the common areas where different colours can be used? 

Warm to Warm White -
Hallway, bedroom, living room.
White to Cool White - Office, retail, kitchen, bathroom, study. 
Daylight - Kitchen, bathroom, retail, commercial, art studios.  

GU10 Used For: 
Kitchens, track style spot lights, bathrooms and retail showrooms. Display, and directional down lighting. Also recessed lighting. Twist and Lock, 2 
connectors.
