Plus, a motion sensing, low-glow lamp makes middle-of-the-night bathroom runs possible without tripping or turning on those obnoxious overhead lights.

Perhaps the most whimsical of the new Echo products is the Echo Glow Lamp, which is basically a glowing light orb that can be controlled by an Echo.

But Casper isn't sleeping on its competition, as the company continues to expand into new product areas (along with mattresses, Casper now sells pillows, sheets, dog mattresses and, most recently, an $89 bedside light called the Casper Glow lamp).

The start-up is moving beyond mattresses as it tries to cater to more millennial must-have niches, including sheets and bed frames, even a bedside light called the Casper Glow lamp, which debuted with a lot of promise but mixed reviews.

Born in Elmina, Antwi moved to Accra at age nine to live with his sister. He was subsequently recruited by Glow Lamp Academy, a programme run by former Ghana international Nii Lamptey, where he became one of the academy's top prospects.

In April 2018, Casper introduced an adjustable bed frame. In June 2018, the company has added to its (one-pillow) pillow line with a new product: the Nap Pillow. In August 2018, Casper refreshed their bedding line with new sheets, along with releasing a nightstand table and bed frame. In early 2019, Casper launched the Casper Glow lamp, an $89 wireless bedside reading light.

In February 2019, Antwi had agreed to sign with Belgian First Division A club Gent, but was unable to secure a Belgian visa. He was subsequently sought after by clubs in England, Hungary and Canada. In October 2019, Antwi scored the tying goal in a shock 2–1 come-from-behind win for Glow Lamp Academy in a friendly against Ghana Premier League side Hearts of Oak.

Lamptey retired from football in 2008. He now breeds cattle and sheep on a farm on the outskirts of Accra. He served as a pundit on Ghanaian television during the 2014 World Cup. He also founded Glow-lamp International School , so as to give back to society and ensure than children have the chance to learn to read and write: something he was never able to do.

Like other gas discharge lamps, the neon bulb has negative resistance; its voltage falls with increasing current after the bulb reaches its breakdown voltage. Therefore, the bulb has hysteresis; its turn-off (extinction) voltage is lower than its turn-on (breakdown) voltage. This allows it to be used as an active switching element. Neon bulbs were used to make relaxation oscillator circuits, using this mechanism, sometimes referred to as the Pearson–Anson effectGE Glow Lamp Manual 1965 , p.

A flicker light bulb, flicker flame light bulb or flicker glow lamp is a gas-discharge lamp which produces light by ionizing a gas, usually neon mixed with helium and a small amount of nitrogen gas, by an electric current passing through two flame shaped electrode screens coated with partially decomposed barium azide. The ionized gas moves randomly between the two electrodes which produces a flickering effect, often marketed as suggestive of a candle flame (see image).

14-18 for low frequency applications such as flashing warning lights, stroboscopes tone generators in electronic organs, and as time bases and deflection oscillators in early cathode ray oscilloscopes. Neon bulbs can also be bistable, and were even used to build digital logic circuits such as logic gates, flip-flop, binary memories, and digital counters.GE Glow Lamp Manual 1965 , p.35-36, 41-66 These applications were sufficiently common that manufacturers made neon bulbs specifically for this use, sometimes called "circuit-component" lamps.

While these lamps are now antiques, the technology of the neon glow lamp developed into contemporary plasma displays and televisions. Neon was discovered in 1898 by the British scientists William Ramsay and Morris W. Travers. After obtaining pure neon from the atmosphere, they explored its properties using an "electrical gas-discharge" tube that was similar to the tubes used for neon signs today. Georges Claude, a French engineer and inventor, presented neon tube lighting in essentially its modern form at the Paris Motor Show, December 3–18, 1910.

A General Electric NE-34 glow lamp, manufactured circa 1930 Neon was discovered in 1898 by William Ramsay and Morris W. Travers. The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers later wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget." Neon's scarcity precluded its prompt application for electrical lighting along the lines of Moore tubes, which used electric discharges in nitrogen. Moore tubes were commercialized by their inventor, Daniel McFarlan Moore, in the early 1900s.

Instruments such as analog voltmeters will indicate up-scale when the instrument's negative lead is connected to the negative pole of a device under test, and the positive lead to the positive terminal. A reversed analog instrument will indicate down-scale, forcing the pointer against the scale end stop; this may damage a sensitive instrument. Digital instruments may indicate reverse polarity of connection with a minus sign before the numerical measurement. A test light using a neon glow lamp will indicate polarity by inspection of the glow around the lamp electrodes; the electrode connected to the negative pole of the circuit will have a glow around it.

The color of the light depends on the gas in the tube. Neon lights were named for neon, a noble gas which gives off a popular orange light, but other gases and chemicals are used to produce other colors, such as hydrogen (red), helium (yellow), carbon dioxide (white), and mercury (blue). Neon tubes can be fabricated in curving artistic shapes, to form letters or pictures. They are mainly used to make dramatic, multicolored glowing signage for advertising, called neon signs, which were popular from the 1920s to 1960s and again in the 1980s. The term can also refer to the miniature neon glow lamp, developed in 1917, about seven years after neon tube lighting.

NE-2 type neon lamp powered by alternating current (AC) A neon lamp (also neon glow lamp) is a miniature gas discharge lamp. The lamp typically consists of a small glass capsule that contains a mixture of neon and other gases at a low pressure and two electrodes (an anode and a cathode). When sufficient voltage is applied and sufficient current is supplied between the electrodes, the lamp produces an orange glow discharge. The glowing portion in the lamp is a thin region near the cathode; the larger and much longer neon signs are also glow discharges, but they use the positive column which is not present in the ordinary neon lamp.

Nii Odartey Lamptey (born 10 December 1974) is a Ghanaian former professional footballer and current assistant manager of Sekondi Wise Fighters as well as the proprietor of a school in Accra called Glow-Lamp International School. During his career he played as a striker from 1990 until 2008 notably for Aston Villa, PSV Eindhoven, Coventry City and the Ghana national football team. He is known foremost for his erratic career, in which he became a superstar as a teenager and then suffered a long string of failures which burnt him out well before his time. Lamptey has been used as a byword for a cautionary tale of putting too much pressure on young players to be successful.

A lightning arrester may be a spark gap or may have a block of a semiconducting material such as silicon carbide or zinc oxide. "Thyrite" was the trade name used by General Electric for the silicon carbide composite used in their arrester and varistor products. Some spark gaps are open to the air, but most modern varieties are filled with a precision gas mixture, and have a small amount of radioactive material to encourage the gas to ionize when the voltage across the gap reaches a specified level. Other designs of lightning arresters use a glow-discharge tube (essentially like a neon glow lamp) connected between the protected conductor and ground, or voltage-activated solid-state switches called varistors or MOVs.
