How watts and lumens differ
Watts describe energy use, while lumens describe light output. Compare both when evaluating brightness and efficiency.
Lighting product specification guide
Plain-language explanations of terms and numbers commonly found on product pages, making models easier to compare and list for quotation.
Information commonly found on product pages
Each group of numbers describes energy use, light output, colour quality, distribution or the protection level of a product.
Match colour temperature to the activity
Warm light feels relaxed, neutral light supports natural colour, and cooler white light suits spaces that need crisp visibility.
When the colour of objects matters
CRI indicates how naturally colours appear under a light source, which matters for retail, food, art and material finishes.
Distribution changes how a space feels
Narrow beams create focus and wide beams spread light. Mounting height and distance also affect the size of the light pool.
More brightness does not always mean more comfort
Luminaire position, viewing angle, shielding and reflective surfaces all affect glare and should be considered with light output.
Outdoor lighting needs more than good design
Check the IP rating, material, exposure to water, cable connections and heat management for the real environment.
