Question: Will this bulb work with the dusk to dawn light? Will this bulb work with daylight sensors?
Document: After a week I have noticed pratically no bug mess around the light fixture so I do leave these on all night. They work prefectly in dusk to dawn sensors. The nice thing is that two of these bulbs use as much energy as a standard night light bulb (4 watts). LED lights are a little pricey but, I think the savings in electricity will more than pay for itself. Plus, these are much safer than fluorescent bulbs.
And by then, I'm sure the technology will be even better. My only reservation is: is it really using only 2 watts?? If so, then leaving it on all day still uses much less energy than the 14 watt cfl I tried to use from dusk to dawn. In fact, I wouldn't be surprised if the fancy digital timer switches use just as much energy as this light bulb.
I have put these into outdoor light cans which are installed under my eaves to illuminate my garage doors. They are on from dusk to dawn, and are not the bug magnets which both the incandescents and florescents have been. They run very cool, and in my climate the heat is the main bug attractor rather than the light. Though they are dimmer than the spots they replaced I am happy with the amount of light for my garage application. I will update this report in the future regarding bulb longevity.
Outside my front door I have two dusk to dawn recessed lighting fixtures in the overhang on a 9-1/2 foot spread and up 8'4'' from the floor. I had 10 watt fluorescents in there and got good even diffused lighting coverage in the area although a little more light than I liked. I was looking for a fluorescent bug light when I ran across these.
I bought two of these to replace two low-wattage fluorescent flood lamps using screw in dusk to dawn adapters . The fluorescent lights are nice in the winter, but in the summer they attract huge amounts of bugs. So much in fact that I usually just leave them off in the summer because I usually eneded up cleaning all the bug mess around the light fixture about two to three times a month. I was searching one day for bug lights and ran across these on Amazon.
I bought 3 of these for the out side of the garage in which I keep my classic cars, they are not bright enough to see my locks where as the cfl I replaced did an admirable job of that, I have also had one of the three fail after only 4 months of use. I have them wired to come on dusk to dawn so they do not get constant use and definitely are not as bright as cfl nor apparatly do not last as long
This product was place in the outside lights for our porch which has a night sentry timer on the circuit and they would not turn off. The sentry allows us to turn the lights on for twelve hours and then off at daylight, but everyday they would still be burning. I replaced them with 25 watt yellow bulbs and they work normal.
About the light output of a good candle, and not yellow. This is the 1st led that didn't work out, I have purchared 20 or so others and they are all much brighter. Complete waste of money, I am looking for a differen't bulb.
I bought this, as I think most people will, for an outside lantern type fixture. It is functional, but it is more directional than I like. By this, I mean that most of the light is pointed towards the top of the bulb and not much goes out in an area effect to the sides. It is still enough to find the right key and work the lock with it.
After trying many timer switches for my porch light which did not work for various reasons, I decided to try a low watt led bulb and just leave it on. I've only had this bulb installed for a couple of days, but the amount of light is just right for seeing everything and getting through my front door. I don't know that it's equivalent to a 50 watt incandescent, but it's close enough.
Answer: yes
