| 1 | It was designed for maximum heat dissipation. | |
| 2 | Old-style incandescent light bulbs generate heat as well as light. | |
| 3 | This characteristic may make the materials ideal for use in drawing heat away from objects that include computer chips. | |
| 4 | Heat management, power supply, and drivers - the bulbs' controlling circuit boards - get more complex. | |
| 5 | Hollow filaments may have dissipated heat, much as the frills of some modern lizards do today. |
