What to know before buying
Listing details to confirm
The listing is inconsistent about conversion direction in one product-description passage, which says E27 to B22, while the title and other specifications describe B22 to E27. It also lists LED as a lamp type despite this being an adapter, and a Touch control method that is unconfirmed for an adapter. Confirm socket and bulb bases and the intended direction before purchase. Disconnect power before installation, stay within the stated wattage limit and leave room for heat dissipation.

Customer feedback highlights positive reports about fit, ease of use and value, alongside mixed functionality experiences. Some report that only one of the two adapters worked.
