At least in an entry. It seems that the sensor needs a certain detection angle. This socket returns at amazon. Attention, the standardization of the lengths of the shuttles has several variants. In particular, these bulbs are 42mm while some others are 39mm. The misen place in a holder that is not appropriate can be difficult! Think the polarity is correct before judging the defective bulb. Finally, these bulbs provide a lmumière powerful and white (but a little more directive) to a very low power consumption. Ideal for the ceiling of the car, éclaireage plate,... On the seller: It must be trèèèèès patient (it comes from Hong-Kong in a small envelope, which is lost sometimes in the road). It was not until the second shipment (for reconsideration) that the packet has arrived at its destination. Bravo to the seller on this item! I bought this batch compared to its very low price, knowing that besides a single light bulb costs 7 €. I use it for the ceiling of a caravan. Two points not to be overlooked :- The light is cold, white or bluish in colour. - The use on the transformer 220/12 my old cara is not stable enough (voltage variable from 12 - 17 V), which causes a flicker rather unpleasant, but I think that this would take place also with a more expensive product. This bulb is far too large and is not tucked into my refrigerator even if the pellet is... I will use for a fume hood, or other... Light bulbs are very effective and not expensive, ignition is immediate, powerful. Fast delivery.Cheap Instruments SD-230 Datalogger 14.00 0-1999:
There was a long time that I was looking for this type of bulb, overpriced usually.. Hello the article corresponds to the description given, as well as the image depicted, it works very well and gives a good charm to my lampReceived 3 days after ordering and well before the dates estimated this a 1 good point. bulb very well packed with bubble wrap and mold styrofoam. light very fast in good qualtéI put 1 star but :1 - first Of all the delivery time abnormally long2 - light bulbs have slammed one after the other after a few days of use under conditions quite normales3 - Data such as 8W, the lighting is very faibleJe does not recommend absolutely this product. These bulbs consume a lot and will give very little. I have light bulbs 36w, which brighten in the 100-and those there to consume 45 to illuminate the 45. The light bulbs illuminates perfectly and are very well finished, but the shipment is very long!! I waited over a month, it is the little negative pointExcellent purchase. The bulbs fit perfectly and the price is three times cheaper than in supermarkets. Remains to be seen whether they are also efficient in the time. Delivered within the agreed time. hello very good product as on the photo I am very sastifai of my order I will recommend to allItem received Quickly. Corresponds well to the description. It is bulb to produce a light well white. At first sight good quality product.. advisedThis bulb was for a small room in which it was imperative to see with a beautiful clarity...Cheap REED Instruments SD-230 SD Series pH/ORP:
my selection criteria : the number of lux, the LED technology, the know-how of the manufacturer and finally the consumer... I am very happy with my purchase. However, for those who search a warm white... the white is rather neutral than warm 2700k... personally this is not a problem.. Not bad but a lifetime really short. In 2 months I had to buy 2 box of 10!!! There are only 2 bulbs work on the 10 I don consseil not to buy if not the 2 that works flashes wellWork very well in my chandelier with balls. By contrast, ordered in warm white and received white cold. But not returned because, as it was for the dining room it's going to a white light! For the duration, to see in time! Price, delivery, color and number of LED's ok, but I have a big doubt as to their operating voltage... With two batteries of 1. 2 V (so 2. 4 V), I managed to burn out a few from the first use (red in particular) !.. For the white and blue, battery Li-Po 3. 7 V is nickel. Deserves details on the operating voltage. Perfect, exactly what I was looking for. Tail'e G9 fits perfectly in place of the halogen that consume 10x more. See in the time. Just a small info, there is always a residual current so it may be that some of the leds stay very dimly lit. Finally, it is really very very low and it does not consume anything. Here I recommend you this seller. I ordered, and paid for, a pack of 6 bulbs 20W. I received bulbs of 10W. It seems that I'm not the first to report this error... Very fast and cheap...Best Buy REED Instruments SD-230 SD Series pH/ORP:
The bulbs are packed in individual so we born not risk damage during storage.. interesting price.... the first bulb has burned out in less than 1 minute!!!! I have set up a second one that works since some days. see the use.. These bulbs are Leds, not halogen... this is even better! I change them as and to the extent that the blisters original slamming. I have no bad surprise, they are all that!!! And it's been months of use now. Seller fast considering the distance ;-) Bands fixed/glued on to protect hand bike and attached as pilot ignition (standing). Bright lighting allowing them to be more visible on the road by 4 wheels with a better description of the wheelbase of the handlebar. Installation is very easy in place of the original. No problem for diameter for mounting on round 2. impeccable product for the rendered lighting in the middle of the night and practice of manipulation to get them to work on the ceilingHappy to have found this kind of bulbs that provide better illumination than the ones that we are proposing currently. The problem is that they burn out quickly (at least some). Is it the quality? Too bad... a cheaper product bought previously consumed more than 10 watts and put out of service the transformer power. The product Osram corresponds exactly to the specifications. the prices are really very attractive and fresh, free shipping to come to Hong Kong.... Nothing wrong for the moment, these bulbs, to see in the long term.On Sale REED Instruments SD-230 SD Series pH/ORP:
great purchase and not expensive, good lighting, good color merciprix compared to the halogenes less expensive and less consuming. For the moment, I've had it for about two months. Works well and not slammed from the other (purchased in supermarkets) 'll already have toasted one or two out of the five that are in place on my floor lamp. Little bigger than filament bulbs, consume less provide better illumination. In the test, It remains to see the strength in time. Correct packaging and on time delivery. I come back on my comment on the product, because it has not kept its promises in time. And the seller is not responding to requests...... This is not a question of price but of serious. Since we can safely assume that the other products of the seller are not more reliable if it does not respond...... produced confrome to the description I have a need hurgent works very well not chaufe not and it illuminates very wellAt first I was a little skeptical about the lighting because these are the first led bulbs that I bought. In the end I'm satisfied with the lighting but from time to time the light bulbs will flash quickly for 2 seconds.REED Instruments SD-230 SD Series pH/ORP Reviews:
I don't understand why, is it my electrical system(from 2009) or is this a defect from the bulbs. Mystery as I don't have answers, I still put 4 stars.. Just after a month of use, already two bulbs HS!!! Fortunately the supplier I will refund the price of the two bulbs... Good product, nothing has report to use, good quality/price ratio, I recommend this product. Installed at the end of a corridor, the ceiling upside down, this bulb Daffodil LEB306 E27 is equipped with a motion detector. It is necessary that the ambient light is low enough for it to trigger. The detector is very sensitive and the light typed warm white is pleasant. The lighting duration is not editable, it remains 30 seconds. I placed in wall sconces to replace energy-saving lamps are the old generation (neon). The advantage is that they light up to max power immediately.Best Buy Instruments SD-230 Datalogger 14.00 0-1999:
The glass is applied to prevent one sees the defects of homogeneity of the diffusion of light, quite noticeable when they just hang from the ceiling, I didn't know that this type of bulb existed, it works very well like on the pictures ;) Just a little flat, you can not set the speed of rotation (in any case, if it is possible I have not found how to do it) I recommend to all those who want to put the lighting for evenings ;). Lot in bulk. High-intensity LEDs Red, Green, Blue, Yellow, White 1 LED HS on the whole batch. All, however, is satisfactoryBeing accustomed for several years to replace my old light bulbs with LED, I have enjoyed the evolution of the latter. The performance of this bulb with its warm color is superior to my expectations. A buy eyes closed! 130 LM instead of 140.... the products sent are actually not those ordered. This is confirmed with the reading of the other commentsInstalled this evening in places of passage (entrance, corridor, WC) : lighting up instant-very cool! Powerful light, a little whiter than an incandescent bulb, but not too annoying. White ceiling, is required because, if oriented to point upwards, the lights illuminate to 180° the ceiling! Have on the long-term. The base is very hot to the bulb worries me a little is that the electronics is concentrated in this small volume is of a high quality to withstand such a temperature! In short, I recommended a 2nd batch (5. 2€ coin it is very interesting).
