The xenon across the electrodes the neon gas will ionize but conduct filled tube is the one the makes all the light. However there almost no current.As the PD approaches the critical value is another flashtube which contains neon gas. It flashes as the neon gas glows with its characteristic orange/pink well but provides a different function as will be explained colour. At about 70V (called the striking voltage) current later.) will flow across the electrodes. The PD must drop to about 60V (the extinction voltage) for current to stop flowing. -

Applications can be severe service (cold, vibration, accessibility), architectural (color, black light), industrial (appliances, germicidal, safety, low voltage, infrared/heat), transportation (aircraft, railroad, marine), and infrastructure (airport, emergency building lighting, traffic signal, sign). Lamp listings are grouped into market/application sections, each containing a “family” of lamps by application or commonalities (such as base, shape, spectral distribution, color temperature), to assist in selection or interchange. Ordering Lamps To order lamps use the GE Order Code, Description and Case Quantity columns. If a lamp is colored BLUE it is stocked in Europe, GREEN is Europe and North America, BLACK is North America only. Otherwise procurement must be through an international distributor or your GE sales representative. North America, European and International sales offices are in the appendix.

Tips and Tricks the Plamp Clip Reflector/Diffuser Notches The
Tips and Tricks The Plamp ® II PP-200 Extending the reach of your Plamp II If you need more reach one option is to attach the Plamp II to an object other than your own tripod. Another option is to extend the length of your Plamp by adding extra links to its arm. We sell a 12” long extension (part # PP-222). The trade-off to adding extra length to your Plamp PP-222 is that it becomes less rigid. 12” Plamp II Extension ($8.00) Reconnecting the ball-and-socket joints of your Plamp If the articulating arm is bent forcefully beyond its normal range of motion, it is possible for the segments to pop out of joint. Fixing this is simply a matter of popping the segments back together. If you have a hard time reconnecting the joints (we realize it takes quite a bit of force), you can warm the socket (female) end in hot water (boiling or near-boiling). This will cause the socket to expand and make it easier to pop the ball portion into place. Adjusting the rotational resistance of the clip The Plamp clip is designed to rotate relative to the articulating arm with slightly less Package Contents: The Plamp II (Qty 1) resistance than is found between similar arm segments. If you desire this resistance to be higher or lower, you may accomplish this by adjusting the Torx 20 mounting screw clockwise (for more resistance) or counter-clockwise (to loosen) Wimberley, Inc.
