Luminosa E27 to B22 Lamp Base Adapter Socket Converter (Pack of 2) / Screw to Bayonet Bulb Socket Adaptor Convertor/CE Certified / 1 Year Warranty

This was the second adapter of this type I had to source after the first pair I received from another brand turned out to be a very poor fit, (at both ends). Thankfully these adapters are ideal & work flawlessly. They screw in very snugly & the bayonet bulb also firmly locks in place as expected. They also haven't raised the height of the bulb itself as much as I was actually expecting them to either, so the bulb still sits nicely below the top level of the lamp shade despite the obvious added height of this adapter. They're solidly constructed & they certainly seem to be very well made, & I really can't complain about the cost either. Ultimately, a very cheap solution to a problem that would have otherwise required an extra £120 to resolve, (& I would have still been stuck with unused hardware of a similar cost too). I'm very happy with them & they do exactly what's required of them, no more, no less. (Although, I really only needed one but at the time of ordering I could only find one supplied as a single & that cost nearly twice as much anyway, at least I'll have the spare just in case, however unlikely.) I would purchase more if required & I'd happily recommend them to others. 5/5.

does the job perfectly, was worried that they wouldn’t work at all but haven’t had any issues what so ever. great value for money, and in my case saved me money. easy to install.

Functions exactly as described. Delivery was fast, actually a day early. Got this to fit my govee smart bulb. Very easy to install & great value for money. Only drawback is it makes the bulb sit a little high, it gives it an extra 2 inches in height. Other than that it's worth it.

Works fine but double check that your light bulb will fit wherever you're putting it WITH the added height of the adapter.

I purchased these as needed them to fit a Govee lightbulb. Fits perfect and is as simple as screwing in a light bulb. In terms of build quality, they seem very durable.

Simple but effective

B.C. to E27 or vice versa, all good stuff. BC bulbs seem to be disappearing but this is a worthwhile unit so that you dont get rid of working bulbs and can utilise lamps and desklights cheaply.

I returned this product as it was unsuitable
