Lumens vs Watts

IRender allows you to specify lamp intensity in Watts. Wattage specifies how much energy the lamp uses.

IRender uses a conversion factor of 17 Lumens per Watt, meaning that a 100 Watt lamp will emit 1700 Lumens. If you know the lamps value in Lumens, divide by 17 when entering it as watts into IRender nXt.

Here is a table of some lamp types and with wattage, Lumens per watt, and total Lumens.
