b'LIGHT BULBS EXPLAINED It is important to choose the correct bulb type. There are two elements to considerbrightness, otherwise IP RATING known as watts or lumens output and light colour, which is measured in the Kelvin scale.

All lighting products within this catalogue are protected at IP20. BRIGHTNESSIn the past, when it was common to see incandescent bulbs in nearly almost all domestic houses, brightness was measured in watts, which is actually a measure of power. Technology has progressed further and the introduction SOLID OBJECTS MOISTURE of energy-saving bulbs has now become the common type of bulb. The wattage output is less effective as a first number Second number measure of brightness as new bulbs are lower in power consummation and more efficient in light output. So, alternately the light output is measured in lumens (lm).No protection 0 0 No protectionThe higher the number of lumens, the brighter the light.Use this chart to see equivalent watt and lumen output Protected against solid objects Protected against vertically for old-style incandescent and the three types of energy-saving bulbs (LEDs, halogens and CFLs).up to 50mm e.g. accidental 1 1 falling drops of water e.g.touch by hands Ingress condensationProtection As a comparative guide, around 400lm would be reasonable for a bed-side lamp, whereas you may require Protected against solid objects 2 sprays of water up to 15 deg between 1,500 and 3,000 lumens for a good-sized living room.up to 12mm e.g. fingers 2 Protected against directfrom the verticalProtected against solid objects 3 Protected against direct BRIGHTNESS 220+ 400+ 700+ 900+ 1300+over 2.5mm e.g. tools 3 sprays of water up to 60 deg LED 4W 6W 10W 13W 18WIP 65from the verticalProtected against solid objects 4 Protected against water CFL 6W 9W 12W 15W 20Wover 1mm e.g. wires 4 sprayed from all directions Halogen 18W 28W 42W 53W 70WProtected against dust - - limited ingress permittedlimited ingress (no harmful 5 Protected against low Standard 25W 40W 60W 75W 100Wdeposit) 5 pressure jets of water fromall directions - limitedTotally protected against dust 6 ingress permitted COLOUR OF LIGHT Protected against strong jets The colour of light is measured in Kelvin, which is actually a measure of temperaturethis is how cool or 6 of water e.g. for use on warm the light is.
