Yet another WiFi light bulb

Eight months ago I reviewed and hacked the AiLight WiFi light bulb by AiThinker. By the time there was a number of people doing the same because of a key reason: it sports an ESP8266 microcontroller and it is based on the OpenLight by Noduino, that had already provided open source code for the LED driver inside, the MY9291.

Let time pass and I was doing the same with the Sonoff B1 light bulb by Itead Studio. That was two months ago and the conclusion was that the AiLight is brighter the the B1 but the lacks warm white channel the Sonoff bulb has.

And now here I have yet another WiFi light bulb, the Arilux E27 Smart Bulb. It looks pretty much like the other two, same shape, same microcontroller, same driver, but different base again and most important: different LEDs. So how does this one compare to the other ones?

Sonoff B1, lights and shades

Six months ago I was reviewing the AiThinker AiLight, a great looking light bulb with an embedded ESP8266EX microcontroller, driven by a MY9291 LED driver. Just before summer IteadStudio released it’s Sonoff B1 [Itead.cc] light bulb, heavily inspired (probably same manufacturer) by the AiLight, at least on the design.

Now that IteadStudio has become popular between the home automation community you can also find the Sonoff B1 on global marketplaces like Ebay or Aliexpress for around 13€.

A closer look at the B1 uncovers some important differences. But before going deeper into the details let me first say that this post will probably look more like a review, at least more than I use to write. And second, yes: ESPurna supports the Sonoff B1 🙂
