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 global average sales price (ASP) of 40-watt equivalent LED light bulbs in June fell 0.2% compared with the prior month to US$9.5, says the latest price report from LEDinside, a division of TrendForce. The global ASP of 60-watt equivalent light bulb also dropped 0.1% monthly to US$12.9.
