Optimal wattage depends on several factors including the size of the growing area and the type of plants. Plants that require more light (i.e. tomatoes), need a higher wattage system.
The wattage rating of a timer is governed by the manufactures specification. As long as the light bulbs wattage rating is not higher than the timers rating, the timer will be alright to use in the circuit. The circuits load is what governs the wattage of the circuit.
No, a higher wattage INCANDESCENT light bulb uses more current than a lower wattage INCANDESCENT light bulb. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.
Energy use is measured in watts. The watts used by a light bulb is on the package or the bulb. Find bulbs with the same wattage but different physical sizes if you want to prove this.
A switch does not use wattage, or consume power which is a better way of putting it. It depends on what appliance is being controlled by the switch.
The question is "use less of what?". If they are both the same wattage the 240 V light will use 1/2 the current of a 120 V light.

Depending on the wattage and type of the light, they are used as an alternative to the sun. Using grow lights can maximize the time your plants spend growing underneath them. Be careful, though, some plants do not like certain types of lighting and can be burned by them.

Also CFL and LED light bulbs use much less actual wattage than their equivalent wattage. It is best to look at the datasheet for each individual type of light bulb. They can vary from milliwatts to kilowatts, depending on the purpose the light bulb was intended for.
use low wattage light bulbs
If you put two incandescent bulbs of the same wattage in series, they will both light with the same intensity. If one is lower wattage than the other, the lower wattage bulb will light brighter than the oter one. If you put two 115 volt bulbs of the same wattage in series across 230 volts, both will light equally, but if you use dissimilar wattages, the smaller one will burn out.

Yes, it is possible to use a grapefruit as a battery, the lightbulb has to be fairly low wattage though.
A 60 watt bulb give a light that is bright enough to see by, but not so bright as to be blinding. anonymous@oola.com
yes <<>> There might be a problem. It depends on what the wattage of the flood light is. If the wattage is higher than what the fixture is rated for then it is not a good idea to use it. Look inside of the recessed fixture and look for the label that was put there by the manufacturer. It will state what the maximum wattage the fixture can legally handle.
