Kosen Smart Bulb

How does the Kosen Smart Bulb work?

Smart light bulbs use wireless technologies to connect to your smartphone and allow you to control the bulb from an app. The Kosen Smart Bulb uses Wi-Fi while other smart bulbs may use other wireless protocols such as Bluetooth, Z-Wave or Zigbee.

What does E27 or B22 mean?

E27 and B22 refer to the base type of a light bulb. Check your lamp's specifications to determine which base type you need. You don't want to get this wrong! 

The "E" in E27 refers to the Edison screw base while the "27" means that the base diameter is 27mm. The E27 is a screw in fit. This base is the most common in Australia. 

B22 denotes a "Bayonet" base with 22mm diameter, which is a simple push and twist to fit.

Currently we do not offer E14 smart bulbs.

What does 1100 lumens mean?

A lumen is the amount of light a bulb gives off. More lumens means brighter light, while fewer lumens means dimmer light. A typical smart bulb produces 800 lumens, but the Kosen Smart Bulb produces 1100 lumens, which is around 40% brighter.

What does 10W mean?

This refers to the wattage of the bulb, which is the amount of energy it uses over time (technically speaking, it is a unit of power equal to 1 joule per second). When incandescent light bulbs dominated the market, the higher the wattage, the brighter the bulb would be. However, this is no longer the case with LED bulbs, as they have become more energy efficient. So when you are shopping for light bulbs, think lumens not watts.

The Kosen Smart Bulb produces up to 1,100 lumens, which is equivalent in brightness to a 75W traditional incandescent light bulb.

How much energy does the Kosen Smart Bulb use? 

The wattage of a light bulb tells you how much energy it uses per hour. From this, you multiply the wattage by the number of hours you are using the light bulb to determine the amount of energy used.

For example, the Kosen Smart Bulb is 10W, and if you use it for 100 hours, then the amount of energy consumed would be 10W x 100 hours = 1,000 Wh or 1kWh (kilowatt-hour).

Assuming you use the Kosen Smart Bulb for 5 hours a day for a year, and the electricity price is $0.25 per kWh, then the annual cost of the Kosen Smart Bulb is $4.56 - less than $5 a year!

Where is the Kosen Smart Bulb made?

Our company is incorporated in Australia. Production takes place in China, where we are able to work closely with our supplier to bring you the highest quality products at an affordable price. 

Is there a warranty?

All Kosen Smart Bulbs come with a 2 year warranty.

Alternatively, you can control the colour of the lights through Google Home or Amazon Alexa, either through the app or using voice.

How do I schedule the lights to turn on and off at a specific time?

  1. Open the Smart Life app.
  2. Select the Kosen Smart Bulb.
  3. Select "More" and "Schedule". Select "Add" to add a new schedule.
  4. Select the time, when it should repeat, and whether you wish to turn the light on or off. Press "Save". You may also add a note and select whether you wish to receive a notification.

How do I schedule the lights to turn on and off at sunrise or sunset?

The way we do this is by creating an automation which is triggered by a condition, using "If then" logic. 

  1. Open the Smart Life app and select "Scene".
  2. In the same screen, press "+" to create a new scene. 
  3. Select "When weather changes" and then "Sunset/Sunrise". 
  4. Choose a city and specify whether you wish the action to be triggered at sunrise or sunset. You can specify an amount of time before or after sunrise/sunset (e.g. 10 minutes before sunset). Once finished, press "Next". You will now see the trigger condition under the "If" section.
  5. Select the "+" next to "Then" and select "Run the device".
  6. Select the Kosen Smart Bulb and click "ON/OFF". Select whether you wish to turn the bulb on or off. You may also select other specifications such as Mode, Brightness, Colour Temperature or Timer. Once finished, press "Next". Repeat this if you wish to use this on multiple smart bulbs.
  7. Press "Save". The automation should now appear on your list of automations. 

Pro tip: If you wish to trigger more complicated actions with multiple devices (e.g. turn on smart lights and close smart blinds), then it is recommended that you setup a "Tap-to-Run". Then, when setting up the automation, you can choose the Tap-to-Run as the action which is triggered (under "Then").

How do I sync the lights with music?

  1. Open the Smart Life app.
  2. Select the Kosen Smart Bulb.
  3. Select "Music". 

The lights will now change colour based on the music it hears from the microphone in your smartphone.
