# Admirably Light Bulb Wattage Per Hour

**For example a certain t12 light bulb that consumes 35 watts of power per hour creates only about 1400 lumens of light.**

**Light bulb wattage per hour**. If you turn on a 60 watt light bulb for 1 hour you have used 60 watt hours of energy. Let s assume your kwh rate is 12 cents and you have a 60 watt incandescent bulb. Conversely a t8 bulb can create the same level of light while only consuming 18 watts of energy per hour. Wattage rating light bulb based hour usage.

Divide the bulb s wattage by 1 000 to convert it to kilowatts. A kilowatt hour is 1 000 watts used for one hour. To convert the power in watts to kilowatt hours multiply 100 watts by 1 hour then divide by 1 000 to find the energy usage in kwh. The incandescent bulb uses 0 06 kw of power and is on for 180 hours a month.

You want to calculate your 60 watt light bulb energy use and cost per hour. Assuming most of this energy leaves us in the form of heat i calculate that on average we radiate 350 000 j of energy per hour. If electricity costs 0 12 per kwh then a 100 watt light bulb will cost 1 2 cents per hour that. A 100 watt light bulb uses 100 watts of power.

Since watt is just joules per second this is roughly equal to energy given off by a 100 watt light bulb. I want to know if i have a 60 watt light bulb running all the time does that meant that it requires 60 watts of electricity to run it for 1 hour. Below are some examples of electrical appliances found in most homes. A mini refrigerator uses about 70 watts per hour or 0 07 kwh therefore it uses about 24 times 0 07 kwh or 1 68 kilowatt hours per day there are varied sizes of mini refrigerators and varying.

Then multiply the bulb s kilowatts by your kwh rate to see how much the bulb will cost you per hour. Power is measured in watts w or joules per second j s. Watt hours are like buckets and watts are like buckets per hour. As an example a 100 watt light bulb operating for ten hours would use one kilowatt hour.

These examples are using a 10 cents per kwh rate. Energy 100 1 1 000 energy 100 1 000 energy 0 1 kwh. Is the wattage rating for light bulb based on a per hour usage. If you have 5 buckets of energy and you pour one bucket per hour you ll be able to pour for 5 hours before you run out.
