Lumens is the measurement of the total light output emitted by a fixture or globe. The higher the lumens rating, the brighter the light. The lower the lumen rating, the duller the light.
Watts is a measurement of the amount of power consumed by the light fitting in order to function. When it comes to traditional incandescent globes the general rule is that the higher the wattage, the brighter the light. However, the use of LED or energy efficient globes allow you to use light fixtures that reduce your power consumption without a reduction in light output. As globes & light fittings are produced in varying levels of watts/lumens ratios it is best when buying a product to not only ensure it is within the recommended wattage of the supplier, but you should also pay close attention to the lumen performance to ensure you are using a globe that performs appropriately.
Colour Rendering Index (CRI) is a rating given to a light sources ability to reveal the true colour of an object to the human eye in comparison to a natural light source. The CRI of a product is reflected as a rating between 0 – 100. The higher the rating, the better the colour rendering ability of the globe. Light sources that rate between 85 and 90 are considered to have good colour rendering ability. Globes above 90 CRI have excellent colour rendering ability.
Colour temperature is a means of determining the light appearance provided by a light globe or fixture. It is usually measured in degrees of Kelvin (K). Typical colour temperatures used within the Australian market are as follows:
Warm white – 2000K to 3000K
Neutral white – 3100K to under 4500K
Cool white – 4600K to 5900K
Daylight – 6000K plus
Globes with warmer colour temperatures are usually suitable for living rooms, kitchens, bedrooms, Globes with neutral and cool or daylight colour temperatures are usually used in the garage, basement, study or bathroom.
With a large variety of globes on the market, it can be difficult to find what you really need. To make this easier, we have included a table of recommended globes and wattages for each product to help simplify your selection. Energy saving lamps, such as CFL, LED or energy saving Halogen are sold in wattages much like regular incandescent globes, but they will use less power whilst producing the same or greater light output.
Remember: DO NOT exceed the recommended wattage for each product outlined in this manual, as our warranty may not apply if overheating occurs. The maximum wattage specified are as per Australian Electrical Safety Standard. The use of globes other than those specifically listed for each product is not recommended.
