SuperFET(TM) MOSFETs withstand high-speed voltage (dv/dt)- and current (di/dt)-switching transients necessary for ballasts to operate at high frequencies. With on-resistance of 0.6-1.2 W and 600 V breakdown voltage, units minimize switching and conduction losses. DPAK-packaged devices meet requirements of joint IPC/JEDEC standard J-STD-020C and are compliant with
For much of the last century, balloons could go far higher than airplanes. One ascent set a record that lasted into the jet age. Compared with the cutting-edge world of aerospace engineering, balloons are the essence of low tech.
» When the wizard Gandolf walked into the caves in Lord of the Rings, he turned the globe atop his scepter into a glowing source of light. So far, lighting engineers can only perform this trick in the movies, but they are always working on new ways to create light.
Of the 147 McPherson High School students who took Advanced Placement (AP) exams last spring, 72.6 percent scored 3 or above. Those scores could earn college credit for these students from participating universities and colleges.
Transtar, one of the UK’s remaining manufacturers of specialist lighting control gear has relocated. The company, which became part of the worldwide Hubbell Electrical Products (HEP) group in July 2005, has moved its operations to HEP’s Glasgow manufacturing facility, which is ISO9001:2000 accredited. “Access to the research, development and technical resources of HEP will allow us to develop the
Available in 120, 240, and 277 Vac input version, Enbryten Down Cool White Model ENBC-120DIM-WHT70-6F-WHT recessed can consumes 15 W and uses 60 lumen/W LEDs. Light with 120 Vac input works with any phase control dimmer. Nichia based LED system and integral patented electronic ballast configuration has expected lifetime of 30,000-50,000 hr based on ambient conditions. UL1598 classified can
Now that the clocks have been turned back and darkness looms in the early evenings, Americans will be flipping on the light switches earlier and more often, which is why the Environmental Protection Agency (EPA) in Washington D.C. urges us to make energy-efficient choices when it comes to lighting.
Retail today is extremely competitive; most stores have tight margins and are constantly looking for ways to attract consumers. To this end, merchants are realizing the importance of lighting.
