For this exact situation that the OP poses (light for the wife), I went with the new Manker E14 III. The prime reason was/is ease of use. But she also appreciates the E14’s floody beam, as opposed to the concentrated spot of some of my other 18650 lights.
While the E14 III comes from the factory with an 18350 tube you can purchase the optional 18650 tube direct from Manker or other third party vendors.
