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.
More lumens equals brighter light, fewer lumens. equals dimmer light. Standard 100-watt bulbs produce about 1600 lumens. Watts-the amount of energy a light bulb uses. The lower the watts, the lower the electric bill. CFLs and LEDs have a lower wattage than incandescent bulbs, but emit the same light output.ore lumens equals brighter light, fewer lumens. equals dimmer light.
