Led Dusk to Dawn Light Sensor Bulb A19 12W E27 1000LM 100W Equivalent Auto On Off Bulb for Indoor Outdoor Courtyard Porch Garage Garden 6000K Daylight 2Pack

Was a bit concerned by the negative reviews referring to the flickering at dusk, but having now installed & witnessed these bulbs 1st hand, have to say that they represent excellent value for money and thus far do exactly what they say on the tin. Sadly, near none of the budget LED bulbs will last for the length specified & that is simply down to internal build quality (yes, not all LED's are built the same) & where they are used. In terms of the former all "ENERGY STAR" RATED LED bulbs have been evaluated and tested to see if they match up to the sales blurb & if there is no energy star approved stamp on the packaging then they haven't, simple as that. Secondly, heat is the LED bulb's worst enemy in the sense that good ventilation & heat dissipation will add hours of extended life to a bulb, but sadly for most people like myself, the bulbs will end up in an enclosed lamp where that heat can and will build over time. In summary, there is a reason why these (and many other budget brands) state on the packaging that they will last "up to" X number of hours (which literally translates as "No, they won't").Above said on to the good points! Well not really wanting to spend twice the amount on a bulb that may last that extra year or so (if I could remember to count the hours), these bulbs still represent good value for money. They worked 1st time, I witnessed no extended flickering at dusk and they switch off like clockwork soon as the sun appears over the horizon. They also cope superbly well with opaque lamp covers (see photo) which for me was essential. Finally, be careful when choosing between Cool & Warm light as the difference in ambience is quite marked. As a rule, always use Warm for more subtle (warming) light, Cool for when sharp brightness and clarity is important (lighting a porch or garage for example). I choose Warm for the X3 lights at the front of our house and as you can see from the photo, they do just that. Not too bright, or too far a reach, but still more than enough to add a decent, warming glow to the entrance. For just under £12 for two, I'm happy (even though I probably will get about half of that 30k hours pojection, but hey, that's not entirely the fault of the bulb).

I bought the 3000K 12w versions end of 2019 for two front door outside lamps. They worked perfectly from day one. The inside light switch is left on permanently with the bulbs photo sensitivity doing all the work of turning on and off night/dawn. They blink about a dozen times when it starts to get dark and the bulbs start to turn on and then they blink again at dawn as they turn off. While the power and brightness is as stated on the tin, I would quite like a brighter version being available with say 2000lm. I hope if I ever see either of these bulbs needing replacing that the brighter version will be available by then.I tried a couple of wifi bulbs before these but found that one of the bulb's connectivity failed, for instance, then the times for going on and off did not sync between bulbs. Then hassle of having to programme the time as the seasons and days became lighter or darker, was an additional piece of work.With these bulbs they are just screw in flick the power switch on and forget. I'm impressed by them in all respects and having thoroughly road tested them for over two years, it was now time to give them the good write up they deserve.

Bulbs arrived promptly but unfortunately one bulb isn't working.. I know I have an option to return for refund but its a bit of hassel and not sure if it's worth the bother.. I've used these type of bulbs for years with great success and I just decided this time to try a different brand but I suppose it got damaged in transit..

Great bulbs no need to think about them on at dusk of at dawn. They do what they say on the box. The light is a bright Clean white makes the outside very secure at night.

this is a very bright ice white light and not warm white ,be aware when ordering these bulbs.Otherwise no complaints.

I was thinking about changing my porch lights for two dusk to dawn as I kept forgetting to turn them off in a morning, I saw these and thought I would give them a go …. They are absolutely fantastic, the light is far better than the bulbs I replaced … no need to buy replacement lanterns AND you don’t have to turn them on and off…., win win…

Having tried other similar products that have not last very long before failing. This one is working well which must be due to the good design that has all the sensors enclosed in the top of bulb and no sensors externally. Brightness is just about right not to bright not to dark

The bulbs arrived quickly and in good condition. I have installed 4 of them outside of the house only a few days ago and all work well. When you turn them on in the daylight, they will light up for 10-15 sec and then go off - this is great as you know at least that they do work. In front of my house, there are 2 lamps on each side of the door (maybe 120 cm away) and I was worried the bulbs would affect each other and not work (in the instruction with the bulbs it is written to keep the distance at least 2 meters). Both work well though, no problem at all. The bulbs seem to be brighter than I thought and give more light. The light colour is warm but not as warm as the previous "normal" LED bulbs. The sensor seems to be very accurate and adds to the longevity of the bulbs, as the bulbs don't switch on too early. From the longevity provided with the instruction, I gather that one bulb should last for 6 years and 8 months working 12 hrs per day on average - will see. So far, I'm very happy with the purchase.14.01.2022 - the bulbs stopped working after 18 moths, which I find anyway a good result and I am happy with the purchase. Will buy them again.
