How Many Lumens Do I Need For A Bright Room Projector

Projector lamp brightness (usually expressed in ANSI lumens) is crucial when choosing a new projector for a bright room.

If you get it wrong when it comes to lumens, the ambient light will wash out the picture and give you a horrible watching experience.

So, how many lumens do you need for a bright room projector?

Ideally, a good projector for bright room should be rated around 2000 to 3000 lumens . This is enough lumens to cancel out the ambient light and give super-clear images with true colors for a great watching experience.

Below, we’ll delve deeper into more details about the right number of lumens for a projector for a room with bright light sources.

How bright should your projector be?


How bright your projector should be depends on where you intend to use it. For instance, you’ll need a high lumen projector for outdoor use in daylight conditions than you’ll need for indoor use.

The more ambient light the space you’re using your new projector is, the brighter a projector you’ll need. Likewise, using a too bright projector (say 2000 to 4000 lumens) in dark room will output overwhelmingly bright images.

A Bright Room Projector

For the brightest, largest spaces that are well-lit, we advise going for a unit rated 3000 lumen or high. 2000-2500 lumens will be sufficient to give you a quality picture in a semi-lit environment.

If you go any lower than this ANSI lumen rating for a bright room, you may get disappointed by the picture quality you’ll get.

If you’re looking for a projector for a dark cinema room, you’ll just need to get a 1000 ANSI lumens rated model. This will sufficiently provide you with high clarity images with vibrant colors. In other words, this projector will ensure you see every pixel in pictures, giving you an enjoyable watching experience.

How bright should your projector be

Our projector lumens chart will give you an idea of how many lumens to consider relative to the amount of ambient light available.

Ambient LightRecommended ANSI lumens rating
Low indoor ambient light300-600
Medium indoor ambient light600 – 1600
High indoor ambient light1600 – 2500
Low outdoor ambient light300 – 800
Medium outdoor ambient light600 – 1000
High outdoor ambient light3000 – 4000

How many lumens for outdoor projector?


If you’re planning to get a movie projector in your backyard space or a mini projector to take with you outdoors, you’ll also need to take note of how much brightness it produces.

The ideal number of lumens will depend on a variety of factors.

Generally, outdoor space is filled with ambient light on a bright, sunny day. Similarly, there may be ambient light at night from the moon, street lighting, sky glow, security lights, etc.

How many lumens for outdoor projector

Most experts recommend getting a 2500-3000 lumens projector for outdoor use. This is the same projector we recommend in our projector lumens guide above for bright room projectors.

However, the screen size may also affect the number of lumens you need for an outdoor projector. If you’re using a giant screen during the day, you may need a bright, more powerful projector up to 5000 lumens!

However, if you’re watching movies outdoors at night on a small screen, around 300-800 lumens unit will work for you.

How many ANSI lumens for outdoor projector?


The ANSI (American National Standard Institute) lumen is the standard used to express a projector’s brightness. ANSI lumens are usually arrived at using smarter methods and involve taking into account many variables.

While the involved measurements are more complicated, the ANSI measurements have several elements that make them more accurate.

It is, therefore, important to always check the projector’s ANSI rating to see if it outputs the necessary brightness or amount of light to meet your needs.

How many ANSI lumens for outdoor projector

Generally, units for use in outdoor spaces with medium to high amounts of ambient light will work with a daylight outdoor projector rated at least 2000 ANSI lumens.

A 600-2000 ANSI lumens projector will work for low to medium outdoor spaces.

And for night use or for an outdoor area with low ambient light, consider a unit with 300 to 800 ANSI lumen ratings.

Besides ambient lighting, your location and the outdoor screen size will also help you determine the ideal amount of ANSI lumens to consider in an outdoor projector.

Can you use a projector in a bright room?


You can use a projector in a bright room, provided you choose the one with the correct number of lumens.

When ambient light hits your screen, it causes the image projected to become dimmer and less saturated. As for the brighter scenes in the pictures, they lack the luster you expect them to display in a completely dark room.

Luckily, you can combat this effect of ambient light by investing in a bright projector that cancels out the ambient light to give you clear pictures. The higher the number of lumens, the easier it becomes to cut through this ambient lighting.

As we mentioned before, the ideal projector for bright room should be super-bright to help combat the effects of ambient lighting. In most cases, 2000-2500 lumens work for a moderately lit room. Go for 3000plus lumens projector lumens for a bright room.

Can you use a projector in a bright room

You can reduce the effects of ambient light in your bright room by dropping the blinds. Yes, drawing the curtains and blinds will help significantly reduce the amount of light in the room and greatly increase the projected image quality.

Above all, make sure you shut off the lights in the room to further reduce ambient lighting and increase projected image clarity and quality.

Final Words

When shopping for a new project for use in your living room or a room with bright light sources, it’s crucial to pay attention to the lamp lumens ratings.

The incorrect number of lumens in a protector will not stand the ambient lighting in your room and give you a bad watching experience.

We advise you to get a projector with a brighter lamp. Anything from 2000 to 3000 ANSI lumen rating will output highly viewable images with vibrant colors and clear pictures in bright rooms.

A 2500 lumens unit qualifies for use in well-lit rooms with medium ambient lighting.

We hope this guide has offered you crucial insights into picking the perfect projector for use in daylight, in a brightly lit room, or for outdoor use.
