How to Choose the Right LED Bulb

Start with the base (E27, GU10, G9…): it must fit the lamp holder. Then choose the lumen output based on the room (400–800 lm for a table lamp, 1,500+ for the living room).

Check if the bulb is dimmable if you're using a dimmer. Check the shape (globe, candle, MR16) to ensure it matches the style of the light fixture.
