Is lux the same as lumens?
Relationship between Lumens & Lux One lux (1 lux) is defined as being equivalent to one lumen spread over an area of one square metre. To put it another way: A specification in lux tells you how many Lumens (total light output) you need given the measured area you are trying to illuminate.
How much lux do plants need?
High-light or full-sun plants need at least 60,000 lux. Medium-light or partial sun plants need at least 35,000 lux. Low light or partial shade plants need at least 15,000 lux. Very low-light plants or heavy shade plants need around 1000 to 5000 lux or less.
Are Ppfd apps accurate?
However, there is one main flaw: It is dangerously inaccurate. The sensor is mainly used to dim the screen brightness according to the available ambient light, which does not require much accuracy at all.
What is Ppfd meter?
The amount of light reaching a surface, e.g. the plant’s leaves, is measured in PPFD, which stands for photosynthetic photon flux density. PPFD measures all photons (light particles) within the PAR spectrum in micromoles per square meter per second (μmol/m²/s). Plants grow from the light that hits the plant’s leaves.
Can a phone measure PAR?
There are a number of smartphone apps which claim to allow you measure PAR (Photosynthetically Active Radiation, the wavelengths of light that grow plants). I have tested the available Apps from Android and IOS on a Samsung S20 and iPhone 12 to see if they can provide accurate PAR readings.
What lux is daylight?

| Natural Light Condition | Typical Lux |
|---|---|
| Direct Sunlight | 32,000 to 100,000 |
| Ambient Daylight | 10,000 to 25,000 |

How do you measure illuminance with an app?
It has units of lumens per square foot (footcandles) or lumens per square meter (lux). A lux is about one-tenth as ‘intense’ as a footcandle (thanks to the ratio of a square meter to a square foot).Search ‘ light meter ’ or ‘ lux meter ’ in the Google App store and you’ll get a list of apps that promise accurate illuminance measurements.
