I want to cut my electric bill. How many YEARS to break even, assuming I replace a wired 60 watt fixture that operates 15 minutes per night?

Sorry I cannot answer your question, because the light completely stopped working after a few months. I was then unable to return it. It was a totally waste of money.

That's a very tough math problem, James! Since you're using 0.015 kWh per day, that's 1 kWh every 67 days. Depending on your power company, 1 kWh probably costs you about 15 cents, so you'd be saving about $1.00 per year...not too impressive. The main reason I bought this was not to save money, but to make it possible to install a security light without needing an outlet.

Since this fixture is all-included, to make a fair comparison, you would need to add up the cost of *everything* you are replacing. Meaning, to find out how much a regular normal 110V lighting system will cost over its lifetime, add up the cost of the fixture, the cost of the wiring, the cost of the electrician to run the wiring, plus the cost of the electricity you use. Compare that to the ~$34 of this light and you will know if you break even.In short, don't compare just the cost of 110V electricity alone to the *entire* cost of the light.

Well James, I have now six Sunforce Led Solar lights in my home. A total of n=5100 lumen, lot's of light for no cost. The lights are working every night for arround eight hours. They doingthis now for three month. Considering that I have n=85 60 watt fixtures working and not paying the city anything; this for approx. five years. that is more or less the time before I break even.

Not at all.. I run it 16 hours a day. It's a 54 watt single bulb. Every two weeks I have been starting seeds on a mat and putting 24 plants (vegetables) in a greenhouse. The root systems under the light are surprisingly healthy. I currently have a couple of hundred plants going. In terms of value for both price and electricity.. You can't lose. Good luck..!!

First of all, you may not have to replace the bulb for many years. The original 18watt double-tube bulb in my Ott-Lite lasted more than 10 years, maybe close to 15 (I couldn't find the sales receipt for the lamp) of daily use. I recently replaced it with an Ott-Lite bulb I bought through Amazon from Light Bulbs Etc., Inc. The price was much less than buying it from Ott-Lite.

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.

Replacing the bulb is a snap, just unscrew a little knob in front and the glass comes right off. I have a 20 watt cfl in there and it's been fine for the last 4 months without being shut off once. You could probably go brighter, but I like the softer light since it's right next to my door.

I am sorry to say I have no idea. This item is connected into the wall, and just like all of my electric lights, television, etc it does not come with a separate bill. Quite frankly, however, I cannot see it using very much since you cannot leave it on for an extended period of time.

Howdy Bp: 24 months, their option as to whst to do. They are not easy to delwith. I had a 2000W go bad (my ault) and my authorized repair station (Colordo Springs did not want to work on it) He told me tht these cheap units are basicall;y a throw away item. So, beware. HOWEVER, I have both the 1000W and the 2000W and they run 24/7. At the current price, if one goes bad, I'll just buy a new one. Hope this helps.BTW their landline # is 1.800.670.0707customerservice@xantrex.com

do not exceed 6500 watt and balance your circuits. you can turn off and on any of up to 10 circuits to stay in your safe zone,dick

LED takes 5 Watts for 40, 7 for 60, and 9 Watts for 75. They will save you money on your electric bill

I always go ahead and swap bulbs to LED type that are 1 or 2 watts each bulb and can have many more lights for the same wattage transformer. You then have the option of getting a lower wattage transformer to make the system even more efficient. And with a 50,000 hour life, you won't be changing bulbs anymore.

Hey Kiwi guy you can get a friend electrician to step down power for you, make a dedicated outlet its easy. from a aussie electrician in NYC

I have heard the bulb will last about 2 years on the average before it has to be replaced. There is also a silver probe that must be replaced when it goes bad. A light will turn on when you have to replace that. I think that may be about 2 years as well. Of course, it depends if you are doing 3 loads per day or 1 load per week.

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.

It all depends on what you're running on it. If I'm using a sixty Watt bulb it's good for 11 1/2 hours. That's what I use it for in the summer at festivals.

No, the lights can't be replaced.At 24 hours per day of continuous use these fixtures can deliver useful light for six years or longer...
