 Novostella Wi-Fi 20W Floodlight

Novostella Wi-Fi 20W Floodlight

Several years ago, I purchased an LED floodlight for use in my garage. It proved to be a handy gadget, providing all the light required when maintaining my elderly and extremely untrustworthy motor scooter.

Since then, I’ve been attempting to convert my house into a Smart Home. To aid in this, I have acquired several lights, a fan, and a robotic vacuum controlled either by my smartphone or via Alexa.

Today, I am taking a close look at a pair of 20W floodlights that have been designed with that very purpose in mind.

These 20W floodlights are sold in sets of two. Each device weighs 21.3 ounces. They are 6 inches wide, 1.25 inches thick, and 4 inches high. The outer case of these devices is composed of flat-black colored aluminum.

A removable and adjustable bracket allows the floodlights to be placed practically anywhere. To ensure good reception via wi-fi, Novostella has provided a screw-on antenna. Each floodlight is equipped with a 52-inch power cable.

An array of LED lights is controlled by either the Smart Life application, Amazon Alexa, or Google Home. The floodlights can be turned on, their brightness adjusted, and different colors selected. Some settings will cause the floodlight to cycle through a specific selection of colors.

The Manufacturer

Novostella is trademarked by Shenzhen Ustellar Technology Ltd.


These floodlights are equipped with a bracket that allows them to be mounted to any surface that can support their weight.

Presently my lights are secured to a pair of 10 x 6 x 1-inch boards. This setup provides portability, and the bases are heavy enough to maintain stability when the floodlight’s angle is adjusted.

Eventually, I plan to remove the board from one floodlight. The light will then be mounted to a ceiling joist in my basement and pointed toward my washer and dryer.


The first step was to ensure that my smartphone was connected to a 2.4G wi-fi network. These floodlights do not support installation using a 5G network.

If I had not already had the Smart Life application installed, it could have been downloaded from either the Apple Store or Google Play. Note that this program requires the user to create an account and log in.

Once I logged into Smart Life, I selected the plus icon located at the top right-hand side of my screen. Then I chose Lighting. The next step was to select the top left-hand light icon.

At this point, I plugged in one of my floodlights and followed the instructions provided by the Novostella user’s guide and the application.

Amazon Alexa

The Novostella user’s guide provides instructions concerning the connection of the floodlights to Amazon Alexa and Google Home. Because my Smart Life application had been previously linked to Amazon Alexa, the new floodlights were automatically added.

Using Amazon Alexa, I can turn the floodlights off and on, adjust brightness and change the color.


Although these floodlights are too bright for use as general lighting, they do make excellent spotlights.

In one case, I aimed a floodlight at my Blue Jay’s mascot and selected a color that made this stuffed animal stand out. The intensity of the light can be adjusted, providing the proper brightness for any given situation.

I installed one floodlight inside my front porch, setting it up to continuously change from one bright color to another. This effect would be useful over the Christmas season or to welcome the Trick or Treaters on Halloween. One of eight different lighting scenes can be selected for this purpose.

I experimented outside the house by aiming the floodlight at a hedge, a fence, and a wall. A long hedge would look particularly attractive when highlighted by a pair of these floodlights.

Wi-Fi Range

According to Novostella, the provided wi-fi antenna increases the operating range of these units to 85 feet.

My garage is located 35 feet from the house. I could turn on a floodlight placed on a bench inside my garage by simply barking out a command to Amazon Alexa while sitting at the kitchen table.

I then added an extension cord and moved the light to the corner of my woodworking shop. This outbuilding is situated 30 feet further from the house. From this position, the floodlight could also be turned on and off using Alexa.

When you consider that the closest wi-fi range extender is located ten feet within my house, the operating range of these floodlights is at least 75 feet. I could not check for maximum range because I ran out of extension cords.

Overall Impression

Build quality appears to be of professional-grade, and I am impressed by the floodlights’ ability to receive commands via wi-fi from distances as far as 75 feet.

If you are looking for a pair of versatile floodlights, this set from Novostella should be at the top of your list.
