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.
The LEDARE produces 600 lumens, with a dimmable design, and a warm color temperture of 2,700k. While it only consumes 10 watts, this LED bulb may prove to be too dim and white for some, so it may be ideal for secondary lighting sources. An IKEA spokesperson states the LEDARE are not covered by a warranty.
