Light Intensity and Housing for Pigeons

Poultry Science, 1976
Four light intensities were used in completely enclosed pigeon housed for 14 hours per 24 hours. Open front pens with only natural light were also used. There were four pens per treatment and five pairs of young, breeding age, White Carneaux per pen for 420 days. Results per treatment, 16, 30, 44 and 61 lumens per sq. m.

STUDY OF THE INTENSITY OF THE LIGHT FLOW OF DENTAL PHOTOPOLYMERIZERS

Український стоматологічний альманах
Relevance. During the direct restoration of teeth with light-curing composites, it is important to irradiate them from the minimum distance to ensure a sufficient amount of light energy for curing, but this is not always achievable. Objective.

The Effects of Light Duration and Intensity with Supplemental Light-Emitting Diode Lights on Grape Photosynthesis, Yield, and Fruit Quality

Agronomy
‘Shine muscat’ grapevines must be cultivated in a protected facility to avoid insects and rain during the rainy season; however, this decreases the light intensity falling on the canopy of grapes.

On the measurement of the luminous intensity of light [PDF]

Journal of the Franklin Institute
Abstract The measurement of the luminous intensity of a ray of light is a problem the solution of which has been repeatedly attempted, but with less satisfactory results than the endeavours to measure the other radiant forces. The problem is susceptible of two divisions, the absolute and the relative measurement of light.
