Lumen is an unavoidable word for the projector industry, which represents the measurement of luminous flux. Put simply, the lumen is the unit of projector brightness; the bigger the lumens value, the brighter the image provided the lumens measurement standards same. Many projector beginners wonder whether 8,000 lumens are good for a projector.
Before answering the question, we need to know lumens by means of common things that we are familiar with.
| Items | Lumens |
| Common Candle | 14 lumens or so |
| sunset | 400 lumens |
| Office Florescent light | 400 lumens |
| Lighting on a movie set | 1,000 lumens |
| 100W Lightbulb | 1,600 lumens |
| Sunny day | 100,000 lumens |
When speaking of lumens in the US, it refers to ANSI lumens. Some projector sellers will simplify the ANSI lumens and label their projectors with lumens directly. There are many projector sellers using light source lumens, LED lumens, or ISO lumens to label their products. All of these lumen units are simplified as lumens in the market, perplexing consumers.
Luckily, there is an online projector lumens converter tool, which can convert different lumens units quickly without manual calculation.
The projector lumens required for different scenarios are also different.
It requires about 1,500 to 2,000 lumens for a dark living room.
As for offices or classrooms, it requires more than 3,000 lumens.
Regarding the church and meeting halls, it needs about 5,000 lumens or above.
For a movie theater, a projector should have a brightness of more than 20,000 lumens.
That is to say, if you are using a projector for home scenarios, 8,000 lumens are good enough for bedrooms and living rooms day or night. Note here, the lumens here should be ANSI lumens. If the 8,000 lumens refer to light source lumens, it is not bright enough for a well-lit environment.
For ISO lumens, LED lumens, ANSI lumens, and light source lumens, you can use this online projector converter tool to convert different lumen units to ANSI lumens.
For example, 8,000 ISO lumens can be converted to 10,000 ANSI lumens. 8,000 LED lumens can be converted into 3333 ANSI lumens. 8,000 light source lumens are about 266 ANSI lumens.
