On average, a desk lamp typically uses between 5-20 watts of electricity. To determine how many kilowatt-hours (kWh) the lamp uses, you would need to multiply the wattage by the number of hours the lamp is on and then divide by 1000. For example, a 10-watt desk lamp used for 5 hours would consume 0.05 kWh (10 watts * 5 hours / 1000).
A kilowatt hour (kWh) is used to measure energy consumption. It is defined as 'the energy consumed, over a period of one hour, at a rate of one kilowatt'.To determine how many kilowatt hours are consumed, you must multiply the power of the lamp, expressed in kilowatts, by the length of time it is in use, expressed in hours.So, a 45-W lamp will use: (45/1000) x 1 = 0.045 kWh per hour of use.
The uses of a magnifier desk lamp are to able to see very small writing/print and be able to read this in a much better light. This can be used for older documents that may have been damaged in the past. Those with eye difficulties would be able to use the lamp for regular reading.
In ten hours, a 200W bulb will use: 10 * 200 = 2000 Watt-hours = 2 kwh
It depends on the btu of the unit
On average, a fan oven typically uses between 2-3 kWh per hour when in use. This can vary depending on the temperature setting and cooking time.
The Advantus Black Computer Fluorescent Desk Lamp is made for that.
probably to measure a lamp depending on if its a desk lamp or a stand up lamp, if you use a stand up lamp, i would suggest using either feet or inches
A desk lamp may seem unnecessary if you use your computer all day long, but using a good lamp can do quite a bit to reduce eyestrain. Simply light the lamp behind your computer monitor.

An led desk lamp is good for reading. It is easier on the eyes than a regular "yellow" bulb. It is also more energy efficient so you will save on your electric bill.

not specifically sunlight, you can use a desk lamp but sunlight, being natural, is probably the best way.
