SynthLight Artificial lighting The elements of a tungsten filament lamp Due to its high melting temperature (3.,655 K), tungsten is used for filaments. The higher the temperature at which the filament operates the more light can be emitted but the sooner the lamp fails or burns out.Step 4: To calculate the number of fittings required use the following formula: Formula: N = (E x A) / (F x uF x LLF) Where: N = Number of Fittings. E = Lux Level Required on Working Plane. A = Area of Room (L x W) F = Total Flux (Lumens) from all the Lamps in one Fitting. UF = Utilisation Factor from the Table for the Fitting to be Used.

When lighting residences, a "one size fits all" approach is unsuccessful, as different rooms require different light - ing and controls. It is important to work on a house-by-house, room-by-room basis to determine specific light-ing design criteria with enough flexibility for a personal touch. The lighting design needs to be kept simple toThe IESNA design procedure described in section 3.3.4is the most widely used and accepted method for determining lighting levels for applications. The method consists of the following: • Choose an acceptable illuminance according to categories A through G, with A being the lowest and G being the highest.
