fluorescent lamp

1. (Electrical Engineering) a type of lamp in which an electrical gas discharge is maintained in a tube with a thin layer of phosphor on its inside surface. The gas, which is often mercury vapour, emits ultraviolet radiation causing the phosphor to fluoresce
2. (Electrical Engineering) a type of lamp in which an electrical discharge is maintained in a tube containing a gas such as neon, mercury vapour, or sodium vapour at low pressure. Gas atoms in the discharge are struck by electrons and fluoresce

fluorescent lamp

fluo·res·cent lamp

A lamp that produces light by exciting the atoms of a mixture of argon gas and mercury vapor with electric current. Ultraviolet rays produced by the excited atoms strike a phosphor coating on the interior surface of the bulb, causing it to emit visible light. Fluorescent lamps are much more efficient than incandescent lamps because the excited atoms give off little of their energy as heat. Compare incandescent lamp.

Type B: Type B retrofits remove the fluorescent lamp and ballast, leaving the existing fixture but requiring the lamp to be directly wired.
If your budget allows, you can avoid the periodic updates to fluorescent lamp standards entirely by installing LED lighting.
Experimental results developed on a fluorescent lamp 32W showed that SRI proposed improved efficiency by 6% compared to the classic SPRI, this is because the SRI does not use a parallel capacitor to the lamp, reducing losses in the cooper of inductance in the tank circuit LC, the proposed circuit SRI also shows a decrease in the switching or conduction losses on MOSFETs.
Then, along came the illuminating engineers and they developed the halophosphor tubular fluorescent lamp. As an example of the impact of this, a new office building was being constructed in the west and it was being equipped with the latest, cost-saving lighting and custom dyed beige carpeting.
A compact fluorescent lamp (CFL), also called compact fluorescent light, energy- saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps.
There appear to be no official recommendations on fluorescent lamp management in Gauteng public schools.
* 20 Watt compact fluorescent lamp equals 1,200 lumen
Starting in June, over 150 newly constructed Walmart stores across the country would install Philips ALTO low-mercury fluorescent lamps. With 80% less mercury than regular fluorescent lamps and no loss in performance, the ALTO lamp was the first fluorescent lamp to pass the Environmental Protection Agency's test for nonhazardous waste.
A normal incandescent bulb of 60 watts can be replaced with fluorescent lamp of 15 watts, saving 45 watts per hour while in case of 100 watt incandescent bulb consumers can save 75 watts per hour by installing fluorescent light of 25 watts, official sources said quoting experts.
Jamaicans are turning out in large numbers to exchange high energy-burning incandescent light bulbs for more efficient fluorescent bulbs, in the final phase of the Cuba-Jamaica Compact Fluorescent Lamp (CFL) Project, also known as the Cuban light bulb program.
For the purpose of increasing energy efficiency at low temperatures special luminaires with so-called heat accumulation tubes [1-6] were developed for accommodating three-band fluorescent lamps. Here the fluorescent lamps are equipped with at least one concentric, translucent full-length protection tube which is fitted in parallel to the fluorescent lamp in the lamp cover and which accumulates the heat radiated by the fluorescent lamp.
When so much control is required in all areas of pharmaceutical manufacturing, the simple use of the right sort of compliant fluorescent lamp can go along way to raising standards and maintaining a safe working environment.
