A: You are probably correct on this one. One of the side effects of Prozac is drowsiness and so this may be what is causing you to be tired in the afternoon. For some people, this effect does go away after a period of time until the drug levels become more level in the body.
Put another way, LEDs use about 12% of the energy used by halogen and filament bulbs to emit the same amount of light. We can also calculate that a 50 Watt halogen spotlight produces about 600 lumens. An LED light would need to be about 6 watt in power to produce the equivalent 600 lumens produced by a 50 watt halogen. We can now see clearly that a 3 watt LED spotlight would produce 300 lumens, not 600 lumens, so definitely not equivalent to a 50 watt halogen bulb.
Bonus: 40-watt equivalents bulbs are underrated. Some of the first general-purpose LED bulbs I tested were rated with the light output of a 40-watt equivalent. I found that they were not quite enough to light up a whole room, but they do the trick in more places than I thought.For example, I have a small LED for an outdoor light and one in the basement.ome of the first general-purpose LED bulbs I tested were rated with the light output of a 40-watt equivalent.
