Bomcosy LED Dusk to Dawn Light Sensor Bulb 9W E27 600LM Auto On Off Bulb for Indoor Courtyard Porch Garage Garden Warm White 3000K 2Pack

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.

Have been looking for a decent night/day bulb. Because my light is in a lobby area, other bulbs with sensors on the housing above the glass just didn’t see enough light for it to turn off and on. The advantage of this bulb is the sensor is within the light glass and so lower in the light fitting. As as result it reads the light better and works perfectly. Good price for two bulbs. Well packaged and protected. Arrived before official delivery date. A good buy 👍

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).

These bulbs work perfectly coming on at dusk and going off at dawn. Hopefully they will last a long time at present I’ve been using them for around 4 months.

Only lasted a year, falling well short of their lifetime guarantee of 30,000 hours. Disappointing.

Best purchase yet! No more forgetting to turn off the outdoor lights in the morning. Work brilliantly. I have 2 of these bulbs either side of the front door and both work perfectly, they come on almost in tandem. Highly recommend these bulbs.

Some are faulty

Great warm yellow glow. The light functions perfectly as well.

Bei diesem Preis macht man nichts falsch. Die Lampen leuchten im Dunkeln den Vorgarten gut aus. Schalten automatisch ein und auch aus. Kaufempfehlung...👍

Warm licht, prettig in het donker, verblinden niet.

Este par de bombillas con sensor crepuscular proporcionan una luz blanca cálida equivalente a 75W y 3000k. Son bombillas E27 que están equipadas con un sensor de luz que se enciende automáticamente por la noche y se apaga al amanecer. Son muy versátiles tanto para exterior como para interior y basta con enchufarlas en un portalámparas para que tengan un funcionamiento correcto ademas de un buen rendimiento. Me aportan seguridad en esos momentos en los que la casa queda vacía proporcionando una luz en su interior que ayuda iluminar estancias sin que tu estés en casa sin que tengas que encenderla físicamente. y para el exterior son perfectas, tanto para terraza como para el jardín o el patio que queda iluminado al caer la noche . Una compra genial,

Donne une lumière satisfaisante par rapport aux spécifications. La durée observée est d'environ 18500 heures en moyenne, un peu plus de la moitié de la durée "garantie" revendiquée de 30000 heures. Mesuré sur des lampes de facade, protégées des intempéries, qui sont allumées pendant environ 8 heures. La détection n'est pas fameuse, la lampe reste allumée en plein jour sauf en été, ou peut-être si la lampe est en ligne directe avec le soleil (ici elles sont côté nord).

Gutes Produkt, sind bei mir jetzt ein paar Wochen im Einsatz und erfüllen meine Erwartungen. Zur Haltbarkeit kann ich noch nicht sagen. Bei sehr trüben Winterwetter haben sie schon mal Probleme rechtzeitig aus zu gehen. Das kann aber auch an der Bauweise der Aussenlampe liegen die oben eine größere Abdeckung hat, dadurch fällt noch weniger Licht in den Sensor. Sonst alles in Ordnung. Gerne wieder
