When it comes to appearance, LED tubes look exactly like fluorescents. However, they are very different. First, LED is a mercury-free lighting solution. There is no costly recycling fees associated with LED lights. And you will never have to worry about a tube dropping and contaminating an ...
Place the tube safely Once you have removed the old tube light, hand it over to someone else or place it on a plain surface so that it doesn’t rollover. Fix the new tube in the fixture Similarly, take the new fluorescent bulb and fix it into the prongs and rotate it. Once it is...
Pressure bladder how-to videos, parts one and two RknRusty Mon Oct 01, 2012 4:02 am This arose from Cribbs' Baby Clown thread since he's thinking of using a Tee Dee and a pressure bladder. Rather than try to write the instructions I did a little video how-to. Here is ...
Fluorescent tubes work on a similar but different principle from incandescents. In the latter, the filament is electrified and provides high resistance to the current, which causes the filament to glow inside a confined glass globe. This creates light, but also a lot of heat. With fluorescents...
The filament in a light bulb is made of a long, incredibly thin length of tungsten metal. In a typical 60-watt bulb, the tungsten filament is about 6.5 feet (2 meters) long but only one-hundredth of an inch thick. The tungsten is arranged in a double coil in order to fit it all ...
Using a simple motor-driven fan and a heating element, hair dryers blow hot air over wet hair to accelerate water evaporation. The heating element is usually a bare, coiled wire that heats up due to electrical resistance. The fan then blows air over this element, warming it before it exits...
In 1895, a German physicist named Wilhelm Roentgen made the discovery while experimenting with electron beams in a gas discharge tube. Roentgen noticed that a fluorescent screen in his lab started to glow when the electron beam was turned on. This response in itself wasn't so surprising -- ...
Plasma cutters are not the only devices to harness the power of plasma. Neon signs, fluorescent lighting and plasma displays, just to name a few, all rely on it to get the job done. These devices use "cool" plasma. Though cool plasma cannot be used to cut metals, it has tons of oth...
To generate 1 watt for an hour, you'll burn approximately 0.85calories. Round that up to about 1 calorie per watt-hour. If you're powering your laptop with a bicycle generator, you'll burn about 15 calories per hour. Not a bad way to stay fit while surfing the internet!
Lights. Visit a nearby hardware store and invest in several light bulbs. Pay attention to “Daylight” fluorescent light bulbs or “Full Spectrum” bulbs. In addition, it will be a great idea to construct a lighting fixture for your DIY photo light box. For this purpose, you may use your...
