Compact Fluorescent (CFL) lighting was long considered a major improvement in light bulbs. CFL tubes became popular because they reduced the energy consumption of using standard incandescent bulbs by 75 percent. Incandescent bulbs were inefficient because they converted 90 percent of the electricity into...
The impending ban on incandescent light bulbs has found many vocal opponents, including those who says CFL or LED bulbs just can’t match the warm glow of an old-fashioned incandescent. We tested all three to find out if they’re right.
incandescent lights on laying hens, and the results showed no influence of the LED vs. incandescent lights on the internal egg quality. The goal of this study was to compare the production performance, welfare, and egg quality of laying hens under LED and FL lights in commercial housing ...
Fluorescent lights do not have the thermal inertia of an incandescent tungsten filament, so they produce flicker at twice their supply frequency, and because they are such large sources, some light is seen from the corner of the eye (which is more sensitive to flicker). Flicker can be ...
Changing the composition of the phosphor powder inside fluorescent tubes changes the spectrum of light produced. Mercury is present in the lamp in both the phosphor powder and in the vapor. Fluorescent lamps are more energy efficient than incandescent light bulbs of an equivalent brightness because ...
I have a couple of big 85watt (advertised as 350watt incandescent-equivalent) from Eiko (5,000K). You can run them on standard medium bases and put them inside a china ball for a large daylight-balanced area filling soft source. I could imagine putting several together to create a big ...
Large White turkey breeder hens were exposed to incandescent or cool-white (CW) fluorescent light of either high or low light intensity as the sole light source. Light treatments were quantified in both photometric and radiometric units for the entire visible spectrum as well as the 600 to 700...
Three categories of birds with different prior lighting experiences were evaluated, including pullets (14-16 weeks of age) reared in incandescent light (IP), layers (44-50 weeks, of age) reared and kept in LED (LL), and layers reared and kept in CFL (CL). Each bird category consisted ...
(PR) and far-red light (PFR) to jointly regulate the development of plant morphology [6,7,8]. Therefore, it was found that plants were susceptible to red and far-red light. At present, halogen and incandescent lamps are mainly used in greenhouses, while white LED panel lamps are ...
