The idea is quite simple, want to test a lamp without having to take any other of nozzle? Want to turn on a light bulb somewhere that has no mouthpiece but has an outlet? If the answer to any of these questions is Yes, You can use a Socket adapter for Lamp E27 Socket with switch.
My use for Socket adapter for Lamp E27 Socket with switch is a little more complex. I want to test the lamps Kill-a-Watt, device that measures the energy consumption of electrical devices, and shows interesting information such as active power (measured in Watts – In), the apparent power (measured in volt-amps – VA) and the power factor.
And why is this important? Today we can compare the brightness of two lamps easily. Be subjectively through our own eyes, whether through a light sensor. Most phones today have a light sensor. Maybe they're not extremely accurate, but they are enough to compare the brightness of two or more lamps. Applications such as Sensor Box for Android allow you to access the sensor data of trivial way. I showed a test of those here in Skooter Blog, in the article on the Ourolux Superled Gold Lamps 60 6In. Then, Since we have two lamps of the same power, We can compare them in terms of luminosity and buy the one that actually lights up more.
But there is at least one problem in this approach. Who ensures that the lamp actually has the power indicated on the package? A lamp 10 Watts has really 10 watts? That is where it comes the Kill-a-Watt. With it you can check how much any device connected to it is consuming in fact.
The problem is that the Kill-a-Watt It wasn't done for lamps, He has an outlet where they can be connected the devices to be measured. And that's where the Socket adapter for Lamp E27 Socket with switch. Of course I could put together something similar using a nozzle, a piece of wire and a plug. But Adapter It is more practical to, e talvez até mais barato, pois custou US$ 0,68 com US$ 1,37 de frete.
O Adaptador de Tomada para Socket de Lâmpada E27 com Interruptor
The Socket adapter for Lamp E27 Socket with switch is quite simple. Ele conta com um plug de tomada no padrão europeu. Note que ele é incompatível com as tomadas do padrão brasileiro e é preciso usar um adaptador. O socket E27 é o socket de lâmpadas mais comum, é o que normalmente temos na maior parte das lâmpadas em nossas residências. O interruptor permite ligar e desligar a lâmpada sem precisar desconectar o adaptador da tomada.

LED Lamp test FLC A10 10W 6400 k with Kill-a-Watt
Para testar o aparato, peguei uma Lâmpada LED FLC A10 10W 6400K, that I showed here in Skooter Blog. Ela é bivolt e alega uma potência de 10W. A embalagem não diz, mas suponho que seja a potência ativa, that is what manufacturers typically indicate. The power factor indicated is > 0,92. The current in 89mA and is 127V 220V is 55mA.
Because we're going to test, We show in the video below:
Note that the active power was almost all the time in 11 In, In addition to the manufacturer's specification. The apparent power was around 13 VA. Por fim, the power factor ranged from 0,88 and 0,90. The chain was around 100mA, with the tension between 123V and 124V at time of test.
What these results mean? Good, first I want to say that I don't know how accurate is the information offered by Kill-a-Watt, so it is possible that these results may be somewhat distorted. Minhas conclusões são baseadas na hipótese de que os resultados são confiáveis. That said, the 11 W indicam que a lâmpada consome além do especificado. Na prática isso significa que o consumo de energia vai ser maior do que o esperado.
As vezes compramos uma lâmpada pela maior luminosidade nos testes com o sensor de luz, mas na prática essa maior luminosidade acabará custando mais caro. Of course 10% de diferença não significa muita coisa, principalmente levando em consideração que o Kill-a-Watt não mostra casas decimais. É possível que o valor esteja sendo arredondado e que a diferença seja menor.
E quanto ao fator de potência? A embalagem dizia que ele deveria ser > 0,92, but Kill-a-Watt mostrou um valor entre 0,88 and 0,90. O que isso significa? Não quero entrar aqui nos detalhes conceituais, because there are many texts on the Internet of people with more expertise than me to explain this subject. Suffice it to say that for homes makes no difference, because residential customers do not take the reactive power. Our meters measure only the active power. But for large consumers, as the industries in General, It makes a difference. They pay by the apparent power and can pay fines if the power factor to stay below a certain preset level.
By specifying the current would be 89 MA in 127 In. The voltage at the time of the test was a little smaller (123~ 124 V), but not enough to justify a 100 mA. Note that o Kill-a-Watt shows the current in Amps with only two decimal places, then we have an error of up to 5 MA only in rounding.
