We are in need of a new website that represents our new facilities however, we do not have funds to have this done at present so please bear with us. To comply with new laws on reducing energy usage, fluorescent and HID lighting systems — both examples of arc discharge lamps — have become more complex and varied in their performance. Take this weekly quiz to test your knowledge of the 2014 National Electrical Code requirements. EC&M previews the highly anticipated Top 50 electrical contractors list, ranked specifically by electrical revenue. Through proven methods including variable frequency drives (VFD), LED lighting and conservation methods and control, many new and existing facilities achieve the savings that they expect.
No other variable frequency drive (VFD) can match the proven reliability, operational flexibility and 20-year lifespan of SINAMICS PERFECT HARMONY medium voltage drives. Lithium-ion battery prices have decreased over the years and are now becoming a viable option for data center UPS.
Historically, lighting controls have always had a singular responsibility: Manage the light. The energy released during an arc flash event can result in severe damage to personnel, equipment, and property.
The Bovie Woods light features two ultraviolet bulbs for superior diagnostic capabilities as well as two daylight fluorescent bulbs with a temperature color of 6,300 degrees Kelvin for general examinations.

A 10-year total cost of ownership (TCO) analysis is provided showing li-ion is 39% less than VRLA despite their capital cost premium. 1) Fluorescent lamp operation A linear fluorescent lamp consists of a tube of glass with an electrode on each end. The sealed tube is filled with a very low pressure (atmosphere) of argon and a small amount of mercury, while a coating of phosphor lines the inside surface of the tube. The electrode, or filament, in a fluorescent lamp is similar to the filament of an incandescent lamp, except for a coating (called the emission mix) that increases the ability to emit electrons. The UV radiation, or energy, absorbed by the phosphor coating is re-radiated as visible light energy.


The industry is moving to electronic ballasts for the newer T8 lamp family, and the newest T5 family of lamps uses only electronic ballasts. Rather than delivering a 60-Hz current to a lamp, the electronic ballast provides an input current between 20,000 Hz and 40,000 Hz, resulting in greater phosphor excitation and thus a higher light output. Typically providing a 10,000 to 15,000 switching cycle, an instant-start ballast generally has the lamps wired in parallel.
Typically providing a 15,000 to 20,000 switching cycle, a rapid-start ballast generally has the lamps wired in series.
Additionally, the case of an electronic ballast should be well grounded and securely mounted against a flat metal surface to achieve heat transfer.
In general, excessive heat is the enemy of all electronic components, potentially shortening the life of the equipment and causing early component failure. A dimming system involves the use of a central controller, a pair of low-voltage 18- to 22-gauge wires to provide control to each ballast, wall-mounted control stations, and remote hand-held controllers. If you follow proper installation techniques, you can avoid the troubleshooting process later on.
Here are some considerations to keep in mind when installing fluorescent dimming systems: (click here to see Fig.
4) If 0V to 10V, powerline and digital electronic ballasts are retrofitted into existing fixtures, the sockets must be of the rapid-start type — not the jumpered (or shunted) instant-start type. With greater lengths, the ballast leads have increased capacitance, which lowers the voltage to the lamps. All linear fluorescent lamps reach their maximum light output at a specific ambient temperature.
1, 2008, MV ballasts can no longer be manufactured or imported under the Energy Policy Act of 2005. The original MH lamp starting method placed an additional electrode, or probe, close to one of the electrodes to initiate a small arc at one electrode end to help the main arc to strike — thus the name “probe-start” lamp. The Security Act of 2007 halts the production of 150W to 500W probe-start MH magnetic ballasted fixtures, beginning this year. Electronic HID ballasts with a continuously dimmable feature down to about 50% of full output power are available, and they have greater dimming efficacy than magnetic types. Maximum ballast-to-lamp distances and minimum wire gauge size should be observed to ensure reliable starting. Increasing conductor size may not boost the allowable maximum distance, and might instead increase wire capacitance, which can further attenuate the ignition pulse.
For ballasts without ignitors (mercury and probe-start MH), the ballast to lamp distance is determined by conductor size to keep any voltage drop below 1%. Visual indications include blackening at the ends of the arc tube and electrode deterioration.
The line voltage should be checked at the fixture, not at the panel, to account for any voltage drop. For constant wattage ballasts (CWA, CWI) the voltage should be within ±10% of the nameplate rating.
If the supply voltage is proper, measuring both the open-circuit voltage and short-circuit current can usually reveal the problem. A ballast may have an integral ignitor, so the safest procedure is to insert a capacitor across the meter for all open-circuit voltage measurements. A CFL that is incompatible with a particular ballast model may not properly start and operate or it could experience early failure. It turns out that the new ballast design is not compatible with the PL-L lamp type, but it is suitable for the PL-C Cluster 4-pin lamp.
