Key Features

Full-Color RGB + Adjustable White Light

These GU10 bulbs support 16 million RGB colors, plus adjustable white light with a color temperature range from 2700K (warm) up to 6500K (cool), giving you full flexibility to match any mood or setting.

Brightness and Efficiency

They deliver around 350 lumens of brightness while consuming only 3.5–4.5 W, depending on the source, making them energy-efficient for continuous smart lighting use.

Bluetooth FastCon Connectivity

Using Broadlink FastCon Bluetooth technology, the bulbs are easy to set up via the Broadlink BLE app. Multiple bulbs can be paired quickly, without complicated Wi-Fi setup at first.

Note: For remote control, voice control, or timers, Broadlink’s Mini Hub (GW4C) or a similar BLE hub is required.

Music Sync & Scenes

You can sync the lights with your music to create dynamic lighting effects, or use preset lighting scenes (like “movie,” “party,” “reading,” etc.) directly from the Broadlink app

Easy Batch Pairing

One of the standout features: you can pair up to 90 bulbs in just one second via the Broadlink app, making installation very efficient—even for larger settings.

Dimmable & Smooth Control

The bulb supports dimming from very low to full brightness, giving you smooth control over its output via the app.

Why Choose the Broadlink LB4G10 EU 4-Pack? (Q&A)
