## How bright is an average light bulb?

The brightness, or lumen levels, of the lights in your home may vary widely, so here’s a rule of thumb: To replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for fewer lumens; if you prefer brighter light, look for more lumens.

## Is a 100 watt bulb bright?

The wattage tells a buyer how much energy the bulb uses, not how bright is. For instance, a 100-watt light bulb is not necessarily brighter than a 40-watt light bulb. This is very relevant today as newer light bulbs use less energy, so wattage is not a reliable measure of a light bulb’s brightness.

## Is a 60 watt bulb bright?

Today’s light bulbs are designed to use less energy. Wattage is no longer a reliable way to gauge a light bulb’s brightness. Lumens measure brightness. For example, a 60-watt incandescent bulb produces about 800 lumens of light.

## How bright is 25 watts?

Energy Star Bulbs

Watts (energy usage) Lumens (light output)
25 200
35 325
40 450
60 800

## Which is brighter 60W or 100W bulb?

Answer: The bulb rated at 100 W will be brighter. When both bulbs are connected to the rated voltage, they will dissipate the rated power. The brightness of a bulb depends on the power it dissipates, so the 100 W bulb will be brighter than the 60 W bulb.

## Can I use 60 watt instead 40?

If you put a 60 watt equivalent CFL bulb into a socket which says to use 40 watt bulbs, then you will have absolutely no problem. The 60 watt equivalent CFL bulb will give light equivalent to an incandescent 60 watt bulb, but will draw only 15 (probably 13) watts of electricity.
