Earlier it was common with light levels in the range 100 - 300 lux for normal activities. Today the light level is more common in the range 500 - 1000 lux - depending on activity. For precision and detailed works the light level may even approach 1500 - 2000 lux. Recommended light levels for different types of work spaces are indicated below:
What is Light Intensity. Light intensity is the magnitude of light energy per unit of area. It is at its greatest near the bulb and diminishes rapidly as it moves away from the light source. For example, plants that are 2 feet from a lamp receive 1/4th of the amount of light received by a plant 1 foot away from the lamp! Crazy no?
Jun 07, 2019· Thomas Atwood June 11, 2019 at 7:13 pm.

Sep 01, 2018· Light intensity (how strong the light is) Light amount (how many hours) Light intensity is measured in units called Lux. Lux is equal to one lumen per square meter. Of course, lumens is a measure of visible light as perceived by the human eye (Plants also …
Takeaway: Working out your garden's daily light integral, or the total amount of light your plants receive during a 24-hour period, is an illuminating process that provides some accurate information to help you determine the exact lighting needs of your plants. Dr. Lynette Morgan reveals ways to maximize the use of your lighting systems using DLI measurements and recommendations for ...
A few marijuana growers I've spoken with swear by them for the cloning/seedling stage, but incandescent lights are probably the only lighting technology that I would suggest completely avoiding when growing plants. Clones and seedlings do not need much light intensity, but, even so, incandescent lights are practically useless for growing plants.
Recommended Light Levels Recommended Light Levels (Illuminance) for Outdoor and Indoor Venues This is an instructor resource with information to be provided to students as the instructor sees fit. Light Level or Illuminance, is the amount of light measured in a plane surface (or the total luminous flux incident on a surface, per unit area).
Lighting Levels in the Workplace | (UK) Health & Safety ... Guidance on the Legislation governing the amount of light needed in the workplace within the UK is mostly restricted to that provided and published by the Health and Safety Executive in HSG 38: ... These guides focus more on recommended illuminance levels for various tasks.
intensity, timing, duration, and color. ... Adhering to professionally recommended light levels provides adequate illumination. Shielded fixtures with efficient light bulbs are more cost-effective because they use less energy by directing the light toward the ground.
what is light intensity, effects on plant growth. Light intensity or light quantity refers to the total amount of light that plants receive. It is also described as the degree of brightness that a plant is exposed to. In contrast to light quality, the description of the intensity of light does not consider wavelength or color.

May 30, 2020· 70,000 – 85,000 lux – a lot of light, some strains thrive at this light level, but some plants (especially auto-flowering and Indica strains) lose their top leaves early under this light intensity. At these levels, lights need to be kept further away for healthy growth
Plants mostly require light in wavelengths of around 430,450,650,675 nano meters (depending on the crop), with highly varied intensity requirements from crop to crop. Lettuce requires mostly the high end of the blue spectrum of light, 650-700 nm, at an intensity of 17 mols/m2/day of PAR (Photosynthetically Active Radiation).
Light levels should always be changed gradually. Plants generally utilize morning light most effectively, since their metabolism is frequently most active in the morning; but as with most rules, there are exceptions. If the habitat climate shows frequent morning overcast, then the plant may benefit from higher light in the afternoon.

The levels are based on a unit of measure called foot candles (fc) or lumens (lm). This rating quantifies how much light is in an area. The following selected foot-candle ranges represent the Illuminating Engineer Society's (IES) current illumination recommendations. Individual applications will determine exact foot-candle levels.
Remended light intensity levels for crusher plants. Light Levels in Buildings Illuminance is measured in foot candles FC or lux 1 FC is the amount of light that hits a 1 square foot surface when 1 lumen is shined from 1 foot away this equates to 1 lumen per square foot 1 lux is the amount of light that hits a 1 square meter surface when 1 lumen is shined from 1 meter away this equates
2,000 – 4,000 LUX: This light intensity is about 40% of midday sun as well as direct light coming through windows. This is considered bright light. It is ideal for many plants that require good and consistent light intensity. 4,000 – 5,000 LUX: This light intensity is about 50% of midday sun. This is strong direct sunlight in a bright room.
Light intensity levels can have a significant effect on photosynthesis rates, which are directly related to a plant's ability to grow. Plant Growth Plant growth processes involve the use of light, carbon dioxide and water to manufacture food for the plant's use, according to the Texas A&M University Agricultural Extension Service.
