| 1. | These colors can be replicated using a gas-discharge lamp containing the same element.
|
| 2. | There his work focused on gas discharge lamps and high temperature resistant materials.
|
| 3. | This included using high-voltage, high-frequency alternating current to light a wireless gas-discharge lamp.
|
| 4. | With some discharge lamps, very high voltage is used to strike the arc.
|
| 5. | At Philips, he did research on lighting systems, especially gas-discharge lamps.
|
| 6. | Cold cathode discharge lamps use higher voltages than hot cathode ones.
|
| 7. | Gas discharge lamps can produce a wide range of colors.
|
| 8. | The fluorescent lamp is perhaps the best known gas-discharge lamp.
