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.
A 23 watt LED for instance, can produce the same amount of light (or lumens) as a 100 watt incandescent â and the technology is only getting better! Why LED Lighting (Lumens) Will Eventually Replace (Watts) As improvements in energy and power evolve, wattage will become irrelevant when trying to determine the brightness of a light. Wattage never did a good job predicting the exact brightness of a light to begin with. It was just a guess based off of the power usage.
