# What is better lumens or watts?

Energy efficient light bulbs – more lumens, less Watts

The most efficient energy saving lights produce the most light (lumens) using the least electricity (Watts). Energy efficiency in lighting products is given in lumens per Watt (lm/W) – the higher the number, the more energy efficient.

Just so, Is 3000 lumens too bright?

In other words, 3,000 lumens is meant to give a room a brighter light. This is not ideal if you have a small room and it’s a bedroom. You don’t want to blind your eyes when you’re about to go to bed. On the other hand, 2,000 lumens is ideal if you wish to light up a 200 square-foot living room.

Which bulb will glow brighter? 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.

Similarly, How do I choose lumens?

Determine the Needed Lumens A lumen is a unit measurement of light. To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens.

## What lumens do I need?

As a handy rule of thumb, a sitting room or bedroom will generally require around 10-20 lumens per square foot, while a bathroom or kitchen will need a stronger level of lighting, at around 70-80 lumens per square foot. To work out the lumens you need, simply multiply the square footage of the room by this figure.

## How far does 4000 lumens go?

## Do regular light bulbs work with dimmer?

One of the most utilitarian bulbs, incandescent bulbs work with any dimmer switch on the market. … However, if the voltage is too strong, these bulbs may burn out. A dimmable fixture is one way to conserve energy and increase the lifespan of an incandescent bulb.

## Which bulb will glow brighter 100w or 60W?

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.

## Is 800 lumens enough to light a room?

With this in mind, we suggest a mid-range 440 – 800 lumen bulb to light up dining areas. … Warmer temperature bulbs make it appear softer – even if it’s bright! Living Room. This is the place you relax, so a softer light usually works best.

## How many lumens is a 40 watt bulb?

How Many Lumens Do You Need? More Lumens = More Light
100 W 1600 up to 72 W
75 W 1100 up to 53 W
60 W 800 up to 43 W
40 W 450 up to 29 W

## How many lumens does a kitchen downlight need?

## What is brighter 4100K or 6500K?

The Range of Color Temperature of Different Light Bulbs

The three primary types of light bulb color temperature are: Soft White (2700K – 3000K), Bright White/Cool White (3500K – 4100K), and Daylight (5000K – 6500K). The higher the Degrees Kelvin, the whiter the color temperature.

## Are daylight LED bulbs full spectrum?

Full Spectrum Bulbs. Though the terms daylight and full spectrum are sometimes used interchangeably, they refer to two different types of lighting. Daylight refers to color temperature, measured in degrees Kelvin. … The higher the CRI of a bulb, the closer it is to representing the full spectrum of visible light.

## Are daylight LED bulbs bad for you?

The AMA says that life-long exposure of the retina and lens to blue peaks from LEDs can increase the risk of cataract and age-related macular degeneration. Studies also reveal that light emitted by LEDs can cause retinal changes, if there is high exposure for even a short period of time.
