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.
23 watts. Typically, the output of a 100-watt incandescent bulb is about 1,600 - 1,700 lumens, a measurement of lighting power. Beginning in mid-2011 new labels will be required on light bulbs. When these labels become available, simply look for a lumens rating to choose a replacement bulb. former 100-watt light bulb manufactured on or after January 1, 2011 and sold in California will have to use 72 watts or less. The 72-watt replacement bulb will provide the same amount of light (called lumens) for lower energy cost.
