This time, the LED bulb is laying on the operating table. Cover with calico. But before go ahead, I want to share something with you.

I agree that we are in 21st gen, which is a tech pro one. But in the thirst for convenience, we shouldn’t fall into the trap of consumerism. I agree that it has got an advanced technology behind it, but lets question ourselves do we actually need it before such purchasing. There are also many recent scientific reports on modern lighting that, CFLs may cause UV related diseases and LEDs may cause blindness in longterm use( Google it & think upon it rationally yourself). So before spending be conscious and question yourself about worthiness factor. So this review is regarding the usage but not regarding the product. Hope this is helpful though it didn’t word a line about the product. – – From Amazon.co.in User

What is your opinion of that?  Think before you buy, it is right to everyone. But for my convenience, I would like to try. LOL.

Get back to business, I felt a bit sad of you, LB120.

At the begining,talking about the IOT thing. You have to consider these factors: Low latency, Scalability, Power consumption, Data quantity, Frequency Band, Secureness, Robustness, Reliability, Existing infrastructure, Number of devices supported, Cost, Standby Time.

The majority of IoT cases require wireless connection, and there are many aspects to consider when choosing a protocol:

  • is the connection over a very short distance, or might it be citywide?
  • what is the volume of data being sent? Is it huge – such as video files – or small?
  • is the speed and frequency fast and continuous (with the benefit of ‘real-time information’), or only occasional (when a device does not need to be ‘on’ all the time, draining power)?

Each IoT solution needs to be considered in its own right. There is no ‘one size fits all’ solution. WiFi is utilised by people using their mobile devices and potentially needing a high bandwidth. IoT is not about using technology for technology’s sake. Whatever IOT innovation you have in mind should, above all, provide a benefit or solve a problem, such as:

  • Saving resources
  • Performing a job better/more efficiently
  • Advancing knowledge

For an IoT project to be successful, it is vital that your IoT solution addresses a real problem or provides a real benefit or efficiency in an existing process. It helps to have clear idea of who your product is specifically designed for (your target audience) and what they need it for (their requirements). For example, Shiva’s gait detection system is aimed at doctors and patients that need to diagnose and treat a gait problem. As well as knowing the problem your project sets out to solve, it is also important to know what makes your product better than what is currently available.

Price



TP-link Selling the smart lighting bulb in different area, but you can find the price on the e-comm website, but I want to say to Tp-link, I hate you, because it do not sell the smart lighting bulb in China Mainland, though it is Chinese Company, I bought this bulb from Amazon China, but the original seller is Amazon USA.

The original price is not in the USD, I have been change to USD, you can click the link to see the price.

Someone may notice the Price in the Amazon Japan is near twice in the US/CA. You can buy 2 bulbs in North America with the same price. That is funny, I do not know the reason, do not the Price strategy, if you know, please feel free to comment.

This bulb is quite heavy in my sight, is it good,  from my experience, it must be potting due to the Heat dissipation.

The length is not standard A-19 dimension, but  it told us that it is a A19 bulb from the package( in the bottom). As the length of standard A19 is 4 38 inches (110 mm)  , but this bulb is 5.1 inch in length. May be due to the size, it can not earn the Energy Star.

Sometime, some user may find it does not fit the lighting fixture.

And form the UL Fine Number, you can find TP-LINK Supplier, which  manufacturer make this bulb. It is SHENZHEN EASTFIELD LIGHTING CO LTD, located in Shenzhen City

  1. how about another brand lifi, with the Wifi control also, what is your suggestion? which is the supplier in China Mainland? thanks your reviewing of the smart lamp. sometimes i would like to have a parter to make smart LED Bulb

    1. thanks ajay, the IOT thing is trend now, LIFI is coming on 2015, funding. I will review their product later, since LIFI and TP-LINK are competitor, as they using the WIFI control. India mark seems there is no outstanding Smart Bulb Brand now. I will check LIFX’s supplier, I think it also in China Mainland. Please await.

  2. thanks your posr i am quite interesting the supplier of tplink. you mension that its supplier is from shenzhen?

    1. Thanks Christoph, the supplier is from Shenzhen city, like the other brand Lifx, they are the same!!! you can go to its website to check. LOL.

  3. there are barriers to adoption for the led smart bulb. like tplink. lifx. philips. the cost is too high. over the past year the led products have dropped rapidly……niw it is time to led smart bulb. though it may be 10usd would be better. reliability, compatibility. secrity issue also should be concerned.
