All lamps have a lumen number and the higher the lumen number the brighter the lamp,
however colour of the lamp (kelvins ) also comes in to play here as a whiter lamp
at 6,000 kelvins and above would always appear brighter to the naked eye than a warmer
colour lamp at the 2,700 kelvins light spectrum even if it has the same lumen output.
A halogen 150w R7 lamp that is used in a standard garden security flood light would
produce around 2,300 lumens and a 26w compact fluorescent would produce around 1,800 lumen. Placing lights closer to the item to be illuminated is a good way of
using a lower lumen lamp rather than trying to flood light a big area.
Care should be taken for local wildlife, insects, and general light pollution, this means the warmer colour spectrum ( 2, 700 kelvin ) does not interfere with insects and general wildlife as much as the blue spectrum ( 4,000 kelvin and above ). Cool white colours can disrupt insects and wildlife's normal night time activity. This also applies to bats where a anti glare light fitting works better as well as reducing overall light pollution in the area.
