I have several identical dimmer switches for low-voltage halogen down-lighting.
Where I have four or five lights/transformers controlled by a dimmer, the "dimmest" setting is much brighter than where just one light/transformer is controlled by a dimmer. A one-light circuit can be dimmed to the level of, say, a 5-watt standard bulb. A five-lights ciruit can only be dimmed to the level of, say, a 40-watt bulb.
Being a fan of atmospheric low light :-) I would like to know if I can make a dimmer reduce the light level more, in the case of the four- or five- light circuit, without compromising the brightness of the same lights when they are not dimmed.
