  • Incandescent, Fluorescent, and Mercury

    In light of many countries legislating the retirement of Thomas Edison’s beloved incandescent lamps in favor of more energy efficient compact fluorescent lamps, it is important to reassure the consumer that this phase-out is both necessary and safe. In order to properly illuminate the concerns regarding compact fluorescent lamps one must first understand their predecessor the incandescent ...

  • Enhanced photobactericidal activity of ZnO nanorods modified by meso-tetrakis(4-sulfonatophenyl)porphyrin under visible LED lamp irradiation

    In this study, zinc oxide (ZnO) nanorods have been synthesized using a simple template-free precipitation technique and deposited on glass substrate. The meso-tetrakis(4-sulfonatophenyl)porphyrin (TPPS) has been synthesized and then immobilized on the surface of ZnO nanorods to prepare an organic/inorganic composite. The samples were characterized by various techniques such as X-ray diffraction, ...

  • Mercury – The Facts, Myths and Clean Up Tips!

    Mercury, the facts. Mercury is an element (Hg on the periodic table) found naturally in the environment. Mercury emissions can come from both natural and man-made sources. It is commonly used in mercury arc lamps for UV curing, however this is a very minimal amount (as little as 5mg) and is used in the lamp to increase the voltage. Due to the harmful effects of Mercury, many ...

  • Characterisation of waste fluorescent lamps to investigate their potential recovery in Turkey

    The investigations in this study were performed on two types of waste linear (tubular) T8 and T12 lamps, which are mostly used in Turkey. Total average value of the mercury mass for the T8 and T12 lamps were calculated to be about 6 mg and 12 mg per lamp, respectively. SEM–EDX elemental analysis showed that approximately 52% of hosphor powders of waste T8 and T12 lamps was measured as calcium ...

  • A novel optical panel photobioreactor for cultivation of microalgae

    In this study, a novel optical panel photobioreactor (OPPBR) equipped with a V-cut/or flat optical panel (OP) and a light source, i.e., light-emitting diodes (LEDs) was developed. The performance of this OPPBR was assessed using cultures of Chlorella vulgaris. Growth rates of biomass were compared in bioreactors operated separately using a V-cut OP, or a flat-plate OP both equipped with LEDs ...

  • Energy Saving Lamps Don't Need to Use Liquid Mercury!

    While mercury in various solid and liquid forms has to be used to make all fluorescent lights (including energy saving light bulbs -  or CFLs) work properly, the mercury does not have to be used in its most dangerous liquid form. It can work just as well in a solid amalgam form combined with other elements. ...

  • Photocatalytic hydrogen generation from water under visible light using core/shell nano-catalysts

    A microemulsion technique was employed to synthesize nano-sized photocatalysts with a core (CdS)/shell (ZnS) structure. The primary particles of the photocatalysts were around 10 nm, and the mean size of the catalyst clusters in water was about 100 nm. The band gaps of the catalysts ranged from 2.25 to 2.46 eV. The experiments of photocatalytic H2 generation showed that the catalysts ...

  • A Better Mousetrap: High-Efficiency Halogen Lamps Are a Superior Energy-Efficient Lighting Solution for Existing Recessed Downlights

    For many homeowners, especially those with children, the kitchen is the most lived-in room in the house. It's a gathering place, a workspace, a study area, an entertainment venue and of course, a room in which to enjoy meals together. Thus, it's not uncommon for kitchen lights to be switched on for four or more hours per day. This presents a legitimate opportunity to save money and reduce air ...

  • Fluorescent Lamp Recycling: Lighting the Future

    An analysis of the lighting industry shows a trend shifting from the usage of incandescent bulbs to fluorescent bulbs. Incandescent bulbs use more fossil fuel energy, are more costly and are less effective than fluorescent bulbs in the amount of artificial light they produce as fluorescents produce more lumens than incandescents. Usage of fluorescent bulbs, however, is not entirely without risk ...


  • Spectral distribution of uv light during aging of medium pressure UV lamps

    As part of a project to validate a UV reactor for disinfection of drinking water, the germicidal output of four medium pressure lamps housed in a continuously operating reactor was followed as a function of time. Spectra were measured monthly and were used in conjunction with radiometer readings to calculate germicidal fluence rates (using DNA absorbance weighting) at the radiometer sensor ...

  • The Alamitos Barrier Recycled Water Project

    Groundwater pumping in the Los Alamitos, California area over the last century has caused groundwater levels to drop, allowing seawater to intrude into the local groundwater aquifer. To prevent additional infiltration by seawater, a coastline barrier of wells injecting fresh water has been in place since 1965. Until recently, imported potable drinking water was injected into the aquifer. However, ...
