How do you know if a light bulb is compatible?

Wattage is the amount of energy a light bulb uses, usually ranging from 40 to 120 watts. Every light fixture has a maximum wattage. You need to choose a light bulb with a wattage amount that is equal to or less than the maximum wattage on your fixture. Don't ever put a high wattage bulb in a low wattage light fixture.

Which bulb will burn the brightest?

The bulb which dissipates more power will glow brighter. In series, both bulbs have the same current flowing through them. The bulb with the higher resistance will have a greater voltage drop across it and therefore have a higher power dissipation and brightness.

Which is brighter 60 watt or 100 watt?

Watts to Lumens – Energy Output to Brightness Produced 60-watt bulb produces 800 lumens of light (most widely used in households) 75-watt bulb produces 1,100 lumens of light. 100-watt bulb produces 1,600 lumens of light. 150-watt bulb produces 2,600 lumens of light.

Is A21 brighter than A19?

A21 bulbs can accommodate higher wattages (and therefore produce more lumens), emitting stronger, brighter light than A19 bulbs. As you can imagine, this also means that A21 bulbs use more energy.

Is there an app to identify bulbs?

LightFinder is a new way to find and buy exactly the light bulb you need and have it delivered to your home. Scan your old bulb with the app and let our AI technology match it up with the right replacement. Select the options that fit your needs, and complete the checkout within the app.
