Very convenient for those, who like me still has lamps with E27 and for which it becomes increasingly difficult to find bulbs !!! The only "fault" that I have seen is that the adapter back the bulb of 2 cm which is to consider following the model of lamp and lampshade which equips this one! Regarding the safety of this adapter (risk of overheating, fire, short circuit) I showed it to a friend electrician to immediately ordered these adapters for personal use .... So if a pro buys it's reassuring! There is a wide range of adapters on the site and those it covers all the needs !!!!
