iLuv’s Rainbow8 is an honest Wi-Fi smartbulb for Apple’s HomeKit, however not way more


By itself iLuv’s new Rainbow8 does what a HomeKit bulb must, and may fulfill most individuals. A poor app and a scarcity of IFTTT or Alexa integration, nevertheless, could imply there are higher selections.

Arguably, simple setup is the primary motive to get the bulb. As a result of it makes use of Wi-Fi as an alternative of Bluetooth, and there is no further hub to connect with your router, setup is ridiculously quick and easy. As soon as it is screwed in and turned on, all you need to do is load up the Rainbow iPhone app, faucet the “+” button so as to add an adjunct, and scan your HomeKit code —voila, you are related. Like every HomeKit gear, you will want an iPad or Apple TV to function a hub in order for you management exterior of the home.

The Rainbow8 helps 16 million colours and is rated at about 800 lumens, roughly equal to a 60-watt incandescent bulb. You could want 2 to four to adequately gentle something however a small room, in different phrases. It is brighter than some LED choices, however not as highly effective as what you will get from corporations like LIFX.

In testing we additionally discovered that veering away from white may typically considerably diminish brightness. That is truly a typical drawback with color-changing smartbulbs, however one thing to think about in the event you plan to wash a room in a specific shade.

A bit of extra troubling is that the colour wheel within the Rainbow app does not at all times correspond effectively with real-world output. We typically needed to fudge our colour choice to get what we had been anticipating, which is in the end simply an inconvenience but nonetheless disappointing.

The app as a complete is arguably the weakest a part of the product. It is serviceable, however typically counterintuitive. To regulate a single bulb as an illustration, you’ll be able to faucet on its icon as soon as to show it on or off, however need to faucet and maintain to see colour and brightness settings. All three of these choices needs to be accessible from the homescreen. We did not less than respect the power to save lots of 5 favourite colours by a bulb’s settings, to not point out choices to rapidly rename a lightweight or assign it to a unique room.

There are different awkward design points. Regardless of HomeKit integration, the one scenes that present up on the homescreen are ones you have created with the app —you need to hit the “Rooms” tab to see every little thing. Some elements of the app have badly-written English, and if you wish to reset a Rainbow8, you will need to delete its entry and flick an influence change on and off 4 occasions.

It is best to manage the accent utilizing Siri or iOS 10’s Dwelling app/Management Middle extension when you’ll be able to. All of Apple’s normal choices apply —you’ll be able to inform your iPhone to “set the Tall Lamp to pink,” as an illustration, or use 3D Contact in Dwelling to rapidly entry brightness and colour settings. The bulb integrates seamlessly with scenes, and naturally helps normal automation choices like timers and geofences.

What it does not assist although is Amazon’s Alexa assistant, or IFTTT (If This Then That). You could not care about Alexa you probably have an Apple Watch or an iPhone with you always, however IFTTT hooks into so many different and software program platforms that assist could also be a reputable motive to go along with different smartbulbs.


It appears to us that the Rainbow8 is greatest suited to individuals who haven’t got heavy HomeKit calls for —say, somebody dwelling in an condominium who simply desires to set the temper for a film, or have just a few lights activate and off after they come and go.

Past that although, it is higher to put money into lights with a whole ecosystem. The Philips Hue platform could have its critics, however it integrates with Alexa, IFTTT, and HomeKit, and has a variety of bulb sorts and switches, to not point out a greater app. LIFX does not assist HomeKit but, however it ought to quickly and it already works with Alexa, IFTTT, and a few particular equipment just like the Nest Thermostat.
