Can anyone guess estimated cost to run this light a month 18 hours a day @ 6.2 cents a KWH

18 x 30 = a a x 324(watts) = b b / 1000(watts in a kw) = c c x .062 = your light bill $10.85 month

If you pay 10 cents per kilowatt hour, one light will cost you 70 cents per year, assuming it is on 24 hours per day, 365 days. If the sensor shuts the light off for any part of the day (month, year), it will be less. You can adjust that amount based on your electricity rates, but this is extremely low wattage and low cost of operation compared to most lighting options.

Not unless you are talking pennies. 8 watts an hour means that at an average 11 cents per kwh, it costs 8x24x30 (wattsxhours in a dayxdays in a month)=5760 watts÷1000 (watts per kwh= 5.76 kwh x 11 cents = 63 cents per month to run.

The voltage is 120 Volt. The consumption is 210 watts, this means 210 x 24 = 5040 Watts per 24 hours, if you pay like me $0.12 per Kilowatt, the cost per day (24 hours) will be $0.60.

My answer is probably useless... But I replied so you weren't left hanging. I hooked up my computer to it and set the cost for kW/h to what I think my service charges. After one month it cost me more to just run my computer than my entire cilco bill was. I am betting that is just me who did it wrong. I haven't tried very hard with it. I don't want to steer you away if you are planning on using it seriously and you are good at what you do. I would say it was of by 400%, but could have been me. THE DISPLAY IS VERY DIM.

It uses 0.8 Watts(W) when lit = 0.0008 kiloWatts(kW). There is 720 hours(h) in a month (24hours*30days) so it takes 0.0008kW*720h = 0.576 kWh.Please check your electricity bill to find the actual amount for expense but a 60W incandescent bulb uses 72x more power

It is low in cost it won't run up your light bill I also had my running all the time it cost me about 3 dollars a month

The device is rated at .8 of a watt. In the worst case, if it runs in a room that stays completely dark 24 hours a day (e.g., never shuts off), for 30.25 days a month it will consume about 6.3 cents of electric power per month, assuming that you pay about 11 cents per kilowatt hour including taxes (as I do). The calculation is .8 watts * 24 hours * 30.25 days / 1000 watts (kilowatt) * .11 (the cost of a kilowatt hour). Your actual cost will probably be something less, because light in the room will shut the light off for some part of the day, and some light in the room will cause the device to dim and thereby also use less power than the .8 watt that it is rated at.

If you run it on the highest setting, it uses 1500 watts per hour which is 1.5 kilowatts. Our power company charges 7 cents per KWH (kilowatt hour) so if we run it on high for an hour, it costs us 10.5 cents an hour. If you use the lower settings, you use lower watts so the cost is less. Your electric bill should tell you how much you are being charged per KWH.

I am running 3 of these in my apartment, one in an unfinished basement, one in bedroom and one in baby's room. My electric bill was around $150.00 - 180.00 before running them and now it is between $250.00 - $300.00 with 3 of these. so probably $30.00 to $40.00 per month per unit I am guessing. I live in Vermont so it is pretty cold right now so it may be lower depending on where you live. The basement unit runs quite a bit due to it being unfinished so it is using more energy.

At .18/kWh, the Low is $3.50/month, the medium is $6.75/month, and the high is $15/month. A fair estimate on auto is about $4.50 per unit per month added to your electricity bill.

The unit itself would draw practically no current either on or off. It may cost over a dollar a year to operate if you pay $0.15 per Kwh for electricity.

Not sure... My friend who is an electrician help install it. He figure out it would cost me about .75 cents an hour to run it up here in Juneau Alaska ..... Think we are up to something like .12 cents a kilowatt hour. Hope that helps you.

It uses 1500 watts at 120 vac. in other words, if you ran it for 1 hour, it would use 1.5 KWH. Where I live a KWH costs around 7.5 cents. So if I ran it for 8 hours a day it would cost around 60 cents a day.

See http://energy.gov/energysaver/articles/estimating-appliance-and-home-electronic-energy-useThe unit is 580 watts.Based on the calculator on the above page, I probably spend about $12/month to run the distiller (I distill about a gallon per day). Assuming I've done the math right ;)

When the light is on, the switch is on. I use six in my home, and I turn them off whenever I leave home. My first instance a few years back, I noticed a savings of about $20+ a month.

I'm not understanding your question but to be honest you the light to last longer than 2 months specially for the dollar amount
