Pros and cons

Pros

Two E27 bulbs are supplied for matching colour and brightness across a pair of fixtures.
The claimed 1100-lumen output and adjustable white-to-colour modes cover both general room lighting and mood effects.
App-based dimming, scene creation and music-reactive effects give more control than a fixed-colour bulb.

What to know before buying

Listing details to confirm

The listing is inconsistent about white-light specifications: the details field gives 2700 Kelvin, while feature text claims adjustable 2700K–5700K. It also lists 220 Volts separately from an accepted range of 220 to 240 Volts and 50 Hertz. Confirm the selected bulb's tunable-white range and electrical compatibility before buying.

Who is it for?

A good fit for

People replacing E27 indoor bulbs who want app-controlled RGB effects as well as adjustable white lighting.
Buyers furnishing two lamps or fixtures and seeking shared lighting effects, dimming and voice control.

Less suited to

People who need a B22 or E14 fitting, outdoor-rated lighting, or a bulb operated without app or voice control.
Buyers who require confirmed Alexa reliability or consistent colour-control behaviour, as customer feedback reports mixed experiences.

Experiences are mixed on app operation, colour options, Alexa compatibility and connection reliability. These differences matter if dependable voice control or precise colour selection is central to use.

Frequently asked questions

Do these bulbs need a hub?

The listing says they connect through the Lepro app using Wi-Fi and Bluetooth, with no additional hub or bridge required.

Can the bulbs produce white light as well as colour?

Yes, the feature text describes RGB colours and tunable white. It gives a 2700K–5700K range, but the details field lists 2700 Kelvin, so confirm the white-light range for the selected listing.

Will these fit a B22 lamp holder?

No. The listed base is E27, so check the fitting in your lamp before ordering.

Can I control them by voice?

Voice control is listed, and the feature text names Alexa and Google Assistant. Customer feedback is mixed on Alexa compatibility and connection reliability.
