Some flashlights weigh more and have bigger incandescent bulbs or LEDs. These may be held using a handle and so they provide more illumination than the compact alternatives. You are going to need to assess the degree of light needed in to choose one out of the two options. Some flashlights include a chord and need being plugged into an electrical outlet for charging. They work until the charge is depleted and after that needs to be plugged last and re-charged. The working is quite similar to that of mobile phones.
