Lightbulb question

[Simpo Two]

Currently I have 100W tungsten light bulbs in each of my ceiling lights, and the brightness is just right..
Some of the units are about to be replaced with ones that hold three bulbs. If I use 3x 40W, will they look as bright as a single 120W or do they 'overlap' a bit?

That not going to cast the same light.

Some one will be along to explain the technical bits but as its going to be coming from more than one point of light it may give a better overall feel rather than 1 big source of light.

Difficult to tell without knowing the specific bulbs - they should all have specs which provide the lumens output for each bulb - you can then add them up for the total output and compare with the original tungsten lamps. if it is 3 x 40W LED bulbs vs 100W Tungsten for example, the 3x40W would be MUCH brighter, if it is 3 x Tungsten lamps then they will likely be brighter but it will be much closer.

Also check the colour temperature versus the original one as this can affect the perceived brightness. Tungsten bulbs tend to be 2700-3000K and classed and "warm white".

Any particular reason for not using LED (if the 40W are Tungsten?)

They'll all be tungsten pearl so hopefully the wattage of the current is comparable to the new.

I don't like the colour of LED lights. Even 'warm' ones look a bit weird to my photographer's expert colour eye.
