FAQs

WHAT DO I NEed?

Minimum requirements:

  • WiFi-enabled router
  • iPhone/iPad (iOS 9.0+) or Android device (KitKat or newer)
  • Smart Lighting from
    • Philips Hue
    • LIFX
    • Nanoleaf (Aurora only) - iOS only currently, Android support planned for later this year

Recommended setup:

  • 4 to 6 color smart bulbs
  • iPhone 6s or newer (for improved Visualizer decoding)
  • Good set of speakers

If you're starting fresh, I recommend 4 to 6 smart bulbs. That way you'll get the most effect variety and good performance. 1 or 2 bulbs is good for strobing or basic pattern making.

PHILIPS HUE VS LiFX? 

Both companies are on their 3rd generation products and offer a variety of light styles, from bulbs to LED strips. LIFX can perform a little faster due to the technology used, but both perform beautifully with Light DJ. Philips Hue has a slightly warmer color palette and the lights transition more softly. All connected products from both companies are supported by Light DJ and both perform great light shows.

CAN I Use Philips Hue and LIFX SIMULTANEOUSLY?

Yes! The latest version of the app now supports combined light groups.

How many Lights can LIGHT DJ support? 

All Light DJ effects will support any number of bulbs (up to the bulb network limit, currently 50 for Philips Hue and 128 for LIFX), however performance may be impacted as more lights are added due to limits of the light hardware. 

If you have a specific situation you're planning for, email me and I can help answer any questions.

WILL IT WORK WITH "WHITE" BULBS? 

Yes! The app will work with LIFX White and Philips Hue White bulbs. You won't see any of the color changes, but White bulbs will flash off & on with different levels of brightness.

Does the nanoleaf Aurora Work Standalone?

Yes! The Nanoleaf Aurora works with or without other lighting products connected.

How Many Nanoleaf AURORAS CAN I CONNECT TO THE APP?

This is a new feature to Light DJ, so I'm not completely sure. I've tested the app with 2 units, but the code will support connecting as many as you'd like. I can't guarantee the quality of connecting more than 2 units currently, but I'll do my best to support as many units as I can up to practical system limits. If you do end up running more than 2 units, please let me know how it's working for you. I will update this information as more users start connecting their units to the app. (Last update: July 17 2017 - Confirmed 4 units working with the app).

Bluetooth Speaker Issues on iOS?

The Visualizer controller uses the iPhone microphone to analyze your music. Due to Apple restrictions, if you are playing audio through a Bluetooth speaker, then the speaker must also have a microphone built-in in order for the app to listen to your music. If your Bluetooth speaker does not include a microphone I recommend using an audio cable to connect directly from the phone to the aux/line-in input on your speaker. Alternatively you can control the lights while using a Bluetooth speaker as long you don't use the features that use the microphone (the Visualizer, auto-tempo, and background mode).

HOW DOES THE APP SET THE SPEED OF THE LIGHTS?

You can set the speed (tempo) of the lights in a number of ways. The microphone input feature will listen and analyze your music to determine the tempo. You can also control the tempo by tapping a button to the beat of the music or via manual speed controls. I prefer tapping, as it is the fastest and most accurate method.

WHAT IF I GET A PHONE CALL WHILE USING THE APP?

Don't worry, receiving a call won't stop the party! The app will continue running in the background if you need to answer an important call.

DOES LIGHT DJ DRAIN MY BATTERY?

Light DJ will not drastically drain your battery. If your device is fully charged you can easily use it all night without having to worry.

WILL USING LIGHT DJ REDUCE THE lifespan OF MY SMART BULBS?

No, Light DJ will not affect the lifespan of your smart light bulbs. One of the great benefits of LED technology is that is allows for quick color changes without putting stress on the bulb. It's the same technology as those blinking lights on your router, just bigger.

CAN LIGHT DJ BE USED WITH OTHER LIGHT BULBS?

As of now, Light DJ can only be used with Philips Hue or LIFX smart light bulbs.

HOW FAST IS THE BULB RESPONSE TIME?

One of the most important qualities to consider for response time is the architecture behind the light bulb.  Hue lights use ZigBee, which is great for sending small, less-frequent messages across the network, but more limited for high frequency commands to a single device. Hue recommends a limit of about 10 bulbs changes per second to any single bulb or 1 change per second on bulb groups.

LIFX bulbs rely completely on WiFi for their data transfer (they each have a WiFi chip embedded), so they intelligently form their own networks - no hub required.  As a result you get completely unnoticeable latency, about 5-10ms. You see the light change colors as soon as you press a button. 

HOW MUCH DOES THE APP COST?

The app is free to download and offers a few in-app purchases if you decide to enable some additional customization features. Upgrades range from $2.99 to $9.99 for the full "Pro Upgrade". You can also download "Light DJ Pro", which is the full app without any of the in-app purchases.

DOES THE APP CONTROL MUSIC?

The app works independently from the music source. You can play your music from any device. I usually play music on my living room stereo when using the app. 

What visualizer do you use in your videos?

I use Plane9 running on my home theater PC for all my visualization needs. It's free for Windows.
