Fluorescent lamps, compact

A number of new technology promotion options are being explored in the lighting area. Work is undeiway on market transformation programs based on bulk procurement for improved efficacy incandescent light bulbs and for compact fluorescent lamps and fixtures. For incandescent lamps, adaptations of the infrared reflective lamp coating that is already in use on reflector bulbs are encouraged by the EPAct requirement. 

Key technologies that are used in modern lighting include electronic ballasts, more efficient tubular fluorescent lamps, compact fluorescent lamps, and lighting controls. Fluorescent lighting is the predominant lighting system installed in post-1980 buildings and is used in 71 percent of floor space. Specialty retail stores use a combination of fluorescent and...

How can the Ecodesign Directive be further developed to handle the RISKCYCLE-topic So far, pollution issues are involved in the context of product evaluation and the derivation of product standards, but rather in the sense of LCA to capture the energy side and the other relevant environmental indicators. The topic of mercury in compact fluorescent lamps (CFL) has made it clear that pollution issues can be quite important in the context of this Directive. However, relevant limits for energy saving lamps were first set by a waste-related regulation, namely the Annex of the WEEE Directive [7].

Of other concern are mercury-containing lamps. At the end-of-life, compact fluorescent lamps/fluorescent tube lights (CFLs/FTFs) are either disposed in bulk (sold in auction) or disposed individually along with municipal waste. Proper and safe collection of these products would mean its intact collection, transportation and recovery of different components including mercury. The case study outlines the possible hazardous consequences due to improper handling of EoL CFLs and FTLs and proposes a future safe collection, recycling and disposal plan. 

CFL (Compact Fluorescent Lamp) In lighting, CFL stands for compact fluorescent lamp, a type of light bulb that provides considerable energy savings over traditional incandescent light bulbs.

This is essentially the story of my invention of the quartz halogen lamp, the incandescent lamp that does not blacken. It is still my hope that an A-line type, quartz halogen lamp will become the lamp of choice where compact fluorescent lamps are not suitable. 

Flat-panel screens contain mercury (except for plasma screens). These flat panel screens require separate internal lighting sources to illuminate the liquid-crystal flat screens from behind. Usually this is a cold-compact fluorescent lamp (CCFL) which contains mercury.

A reasonable number of internal lighting points should be wired that will only take energy-efficient lamps such as fluorescent tubes and compact fluorescent lamps, CFLs.

In a recent work by Nawi et al. (Nawi et al., 2012) conunercially acquired TiO photocatalyst (99% anatase) powder was mixed with epoxidized natural robber-50 (ENR50)/polyvinyl chloride (PVC) blend by ultrasonication and immobilized onto glass plates as TiO -ENRSO-PVC composite via a dip-coating method. Photo etching of the immobihzed TiOj-ENR50-PVC composite was investigated under the irradiation of a 45W compact fluorescent lamp. The composite samples are charac-...

In synthetic contexts, thiyl radicals are known to engage in a number of useful reactions [191-198], including C-H bond abstraction [197, 199-203]. Recently, MacMillan has demonstrated the capacity of catalytically generated thiyl radicals to cleave the C-H bond of benzylic ethers for radical coupling reactions (Fig. 27) to form diaryl methanols (a) [204] or p-amino ethers (b) [205]. The light source is either a Blue LED or a Compact fluorescent lamp (CFL), as designated above. In both reactions, a wide variety of arene components and ether substitutions are tolerated to furnish a diverse set of products and only a catalytic amount of methyl thioglycolate is necessary to affect the desired C-H HAT event. In the formation of diaryl ethers (Fig. 27a), phosphate serves as the base, whereas the P-amino ether...
