E27 connected bulbs are plethora of today. There is something for every taste. But where it is possible to find the little extra with a connected outlet, it is much less easy with light bulbs… As we are still waiting for high-brightness connected bulbs as a basic offer, we decided to test a little new one on the French market: Tronsmart.
So we present to you today their connected bulb TB01 9 W, E27 base, Wi-Fi, autonomous, 800 lm, multicolored (16 million colors, it must be a TM, it is not possible!). It looks like some light bulbs on the market but has big mistakes ...
TRONSMART : home WeBack application
Our bulb is delivered in really high-end packaging, quite flashy, solid and rather outgoing. It includes the visual of the bulb, the QR codes to download WeBack, the characteristics of the bulb and its compatibility with Alexa. You will find the bulb and a notice in French. It does not explain much the installation but more the characteristics. But the main thing is noted on the box: download the WeBack app, install the bulb and presto ...
Smart Life, Tuya or WeBack, it's always the same thing: create an account on the app, screw the bulb to the socket, turn on and off via the switch 2 to 3 times to make it flash quickly and follow the instructions of the application. 2.4 GHz network only.
Indeed, even if the base seems quite close to Tuya, WeBack is quite clear and changes by its design. Even the preliminary step allows you to check your system before pairing.
The color modulation is also very intuitive and allows you to give free rein to your desires, just by sliding on the screen! We can say that this application is a good surprise in principle (even if it also has big flaws)!
TRONSMART TB01: good basics but test not transformed
In terms of the characteristics of the bulb, we are in the middle high of the market: class A +, a power of 9W, 800 lm (790 lux measured at 1 m directly under the lamp). Its theoretical operating time of 20 000 h (more than 2 years and 9 months of permanent operation or 34 years if used 2 hours per day). Color intensity between 2700 and 6500 K. Pretty good…
In terms of design… how to put it? Doesn't she remind you of anything? Oh yes, she looks furiously like a Yeelight. However, the comparison stops there, we are not on the same "luminaire" quality of the finished product, even if it is quite pretty and of good quality. This is a purely personal opinion, but the color white for connected bulbs is much more versatile and upscale than the other colors. The quality of the plastics is good, as are the finishes. It is quite heavy with 240 grams et 10 cm protruding from the socket for maximum diameter of 7 cm. So pretty standard in terms of dimensions.
As seen above, the WeBack application makes it possible to vary the intensity and the heat of the light in color and in white, which is not systematic. However, no scene as on Smart Life but there is a possibility of programming. This is quite limited ...
In terms of colors, this bulb is relatively heterogeneous. the white is very bright and the shades are very good. The color, when we manage to have the desired one, is also very beautiful and quite luminous. The blues in particular are very deep and straightforward. However, the problem concerns a real difficulty in having the desired color and red is almost non-existent. We fall back on blues or yellows / greens but no red… It's quite problematic.
So, you are going to ask us what the WeBack skill gives for Alexa… Well… Good question! The skill exists in Germany and UK but not in France! The manufacturer has been contacted by the Alexians and this one has been working on it since mid-december, but without success… However, the problem is taken into account and it should be solved. But that doesn't change anything for this test, it does not work with Alexa in France contrary to what the box notes and what the advertising announces.
To conclude, this E27 multicolored connected bulb is ultimately quite average considering the price and its results. Avoid, especially as long as the skill is not yet available in France.
