You need at least 2,500 lumens or lux of projector lamp brightness to successfully make your projector image appear in daylight, which is the strongest type of ambient light you’ll ever come across.
How many lumens do you need for direct sunlight?
Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux. Multiplying the figure of 1050 watts per square meter by 93 lumens per watt indicates that bright sunlight provides an illuminance of approximately 98 000 lux (lumens per square meter) on a perpendicular surface at sea level.

What is 6000k in lumens?
Higher color temperatures emit fewer lumens. Color Temperature: 6000k. Lumen output: 2800 lumens. Purpose: 6000k bulbs are traditionally used in headlight applications but can be used as auxiliary lights in fog light applications.
Is 6000 lumens bright for headlights?
6000 Lumen is extremely bright as we know. But we still can find some led car headlights bulbs marked with 8000 Lumen, 10000 Lumen or even 12000 Lumen. … The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source.
