Lumens per watt - do they vary within a given bulb type?
A simple question from a simple mind. You have two lights, both
fluorescent and both 40 watts. On light is 36" long, the other is the
spiral type that fits in a regular incandescent socket. Do they both
give off the same amount of light?
And, do different 40 watt 36" bulbs give off different amounts of
light, or does it just seem that way based on the "Temperature" of the
color?
