Frequently asked question

Does this bulb get temperature hot when left on?

That is a good question, I do not let my light stay on for long periods of time. My daughter uses hers daily for hours and it is not hot to the touch. After being on for hours, I can hold the bulb easily!

Can the color be changed by voice command with Alexa?

Yes, besides Apple HomeKit Siri, VOCOlinc light bulb is also compatible with Alexa, and Google Assistant.

How do you change the bulb to a specific color? I cant figure it out with HomeKit.

Hi, you can use vocolinc App or Home App to change the color, please contact [email protected] to get support if you can not find the specific color.

A lot of these homekit devices work fine with 5ghz after you set them up via your 2.4ghz connection. is this true for the vocolinc?

Yes, been using my vocolincs for months on my 5ghz without any issues

    Absolutely the best HomeKit lights out there

    So for the past few months I have tried out 4 different brands of smart home devices. I test software for a living, if that means anything to you – I say that because every other smart device I have tried has had some of the worst software/hardware I have ever come across, in my professional career.

    With HomeKit, it seems like the best thing to do GENERALLY is to buy your devices straight from the apple store. HOWEVER, the options are extremely limited, expensive, or backordered. Your options from Apple are either Nanoleaf (backordered, good luck) or Phillips Hue + Hue hub ($200 for the first four lights + hub). I have tried neither, for these reasons.

    Some may be tempted to try out Cync (C by GE), JUST DONT, PLEASE. That app, and their hub, is physical evidence that God died a long time ago and hasn’t been replaced. Same with FEIT electric (sold at Lowes) which markets their devices as ‘Siri shortcuts compatible’. Garbage.

    Not only does Vocolinc not require a hub to use with HomeKit, but you don’t even need to download their app. You can set these up by connecting them directly to the Apple Home app. I am at about 5 of these bulbs now, and 6 outlets (including the dual outdoor outlet. They all work great, and the colors are brighter and more vibrant than the other options I have tried. The whites are decently bright, but could probably be just a bit brighter. I find myself needing them at 100% all the time I use the whites. Maybe they have a brighter bulb that I have not looked into yet. If you opt to use the vocolinc app anyway, it is a work of art – you dont need to create an account AT ALL. If you set the devices up in HomeKit first, these wonderful folks have designed their app to automatically pull those devices in and have them ready to go the first time you open it. Beautiful.

    The only real complaint I have is about these bulbs specifically, and I think they have other models that are smaller, but they don’t fit inside a lot of decorative fixtures (globes). They are a bit longer than normal bulbs, and most globes I have are not deep enough fit over these bulbs when oriented vertically. So look into the other vocolinc bulbs if you have smaller fixture globes. I think that is my fault, as I should’ve paid more attention to their size.

    Lastly, during setup, make sure you disable your 5Ghz radios if you have dual band wifi access points. Do not try and connect these to any 5Ghz network, they just wont work. That is usually the case for most smart bulbs and devices like these. You can re-enable the 5GHz radios in your dual band APs after they are setup, so its not a real issue.

    Overall, definitley the best option out there I have found for HomeKit.

    Best HomeKit LED bulb in its price range

    I wanted to replace my Bluetooth warm white dimmable bulbs in my house with HomeKit color changing bulbs that included warm white colors. I was so happy after I bought my first L3 bulb I decided to replace all my bulbs with VOCOLinc L3 bulbs. I now have six L3 bulbs and four Vocolinc smart plugs. These bulbs connect to my home network in seconds and are added to my HomeKit hub completely setup with automation in under 2 minutes. The colors are good and has a very wide pallet of color options that’s about 90%+ of all the Pantone color options available in the Philip Hues bulbs. They have stayed connected to WiFi for months without losing connection. The bulbs maximum brightness exceeds my expectations, and the 1% dim setting is actually 1% where so many other bulbs have no real dimming option below 5%. The smart plugs were also just as easy to setup and add to my HomeKit environment.
