Overview

The TCP Smart WiFi LED Bulb in E27 fitting is the screw-cap equivalent of TCP's B22 smart bulb, covering the same combination of full RGB colour and tuneable white in one bulb. It connects directly to a 2.4GHz WiFi network through the TCP Smart app, with no separate hub needed, and works with Alexa and Google Home for voice control. At 806 lumens from 9W actual draw, it's a like-for-like replacement for a 60W traditional bulb, sized for lamps and pendant fittings using the Edison screw cap common in the UK.

In-Depth Look

The E27 Edison screw fitting is the standard cap for most UK table lamps and pendant fittings, and TCP’s E27 smart bulb brings the same combined colour-and-white functionality as the B22 version to that fitting type.

Light Output and Colour

At 806 lumens from 9W actual draw, this replaces a 60W traditional screw-fitting bulb without a drop in usable brightness. The tuneable white range handles everyday lighting, while 16 million colours and a music sync mode cover mood and accent use when wanted, all from the same bulb rather than needing separate colour and white models.

Setup and Ecosystem

Setup goes through the TCP Smart app over 2.4GHz WiFi, with no hub required, and the bulb works with Alexa and Google Home for voice control. It shares the same app as the B22 version of this bulb and TCP’s smart plugs, so a household with a mix of bayonet and screw fittings can run both from a single ecosystem.

Verdict

For E27 lamps and pendants, this bulb offers the same practical case as its B22 sibling: genuine 60W-equivalent brightness, no hub needed, and flexible enough to cover both colour and everyday white lighting from one bulb.

Who It's For

  • Homeowners with E27 screw-fitting lamps and pendants wanting smart control without an electrician
  • Anyone wanting both mood/colour lighting and practical white light from the same bulb
  • Buyers already using TCP Smart plugs or heating products who want a matching app ecosystem

Pros & Cons

Pros

  • Genuinely covers both colour and tuneable white use cases in one bulb rather than forcing a choice
  • No hub required, unlike some smart bulb ecosystems
  • 806 lumens is a true 60W-equivalent output, bright enough for general room lighting
  • Works with the same TCP Smart app as the brand's plugs and heating panels

Cons

  • 2.4GHz WiFi only, needs a dual-band router split or guest network for older setups
  • Individual bulb control over app rather than local switch can feel slower than a physical dimmer
  • E27 fitting only — check the existing fitting before buying, as it won't suit B22 bayonet fittings
