Differing Findings. Since the early s, researchers have looked for a connection between fluorescent lighting and behavior. Inresearcher James Ott compared the behavior of Florida schoolchildren studying in a room lit by traditional fluorescent bulbs with that of a group in a room lit by newly developed full-spectrum bulbs that mimicked natural daylight.
Fluorescent lighting beats incandescent bulbs in energy efficiency by far, with compact fluorescent lamps (CFLs) using 75% less energy than regular bulbs, according to ENERGY STAR.
But the quality of the light emitted by tube fixtures and CFLs is very poor. Florescent lighting produces a rather cold and often blue-tinged fluorescent light color. A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light.
An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.A fluorescent lamp converts electrical energy into useful light much more efficiently.

Fluorescents were associated with ghoulish green skin - Selection from Set Lighting Technician's Handbook, 4th Edition [Book]. What is a ballast. In a fluorescent lighting system, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps.
Without a ballast to limit its current, a fluorescent lamp connected directly to a high voltage power source would rapidly and. This article series explains how to diagnose and repair fluorescent lights in buildings. Watch out: flickering or dimming lights might indicate a dangerous condition risking a building fire or an electrical shock.
If the simple bulb or starter repairs we describe here don't cure the flickering, switch off the bad-acting light fixture, leave it. Lifetime Of LED vs Fluorescent Grow Lights.
Here again, LED grow lights really outshine fluorescent grow lighting, with LEDs having a usable lifespan of about hours, as compared to about hours for CFL grow lights and to hours for T5.
Some fluorescent lights fall outside this safe range. Fluorescent lighting may increase UV-related eye diseases by up to 12% and, according to our calculations, may cause an additional cases of cataracts and cases of pterygia annually in Australia.
