How do I decide which light bulb shape code I need?

To choose the right light bulb shape, consider the fixture you'll be using it in and look for the code (like A19, G25, or BR30) printed on your old bulb or in your fixture's specifications, ensuring a proper fit and desired light distribution.

I love the vintage look. Are Edison bulbs a good choice for general lighting?

<a href="https://www.homedepot.com/b/Lighting-Light-Bulbs-Edison-Bulbs/N-5yc1vZ2fkol7b?catStyle=ShowProducts?emt=plpfaq_2508_lightbulbs" style="text-decoration: underline;">Edison bulbs</a> are fantastic for adding a warm, decorative touch to your home with their visible filament design and amber glow. Still, they're generally not the most efficient choice for primary lighting due to their lower lumen output. Consider using them in fixtures where the aesthetic is as important as the illumination.

What are dusk to dawn light bulbs, and where would they be most useful for my home?

<a href="https://www.homedepot.com/b/Lighting-Light-Bulbs/Dusk-to-Dawn/N-5yc1vZbmbuZ1z0jv3d?emt=plpfaq_2508_lightbulbs" style="text-decoration: underline;">Dusk to dawn bulbs</a> have a built-in sensor that automatically turns the light on at dusk and off at dawn, providing convenience and enhanced security. These are ideal for outdoor fixtures like porch lights or landscape lighting, ensuring you always have light when needed without worrying about flipping a switch.
