Identification
LAMP
CHARACTERISTICS
Identifying a lamp is much like identifying a person;
both have specific characteristics we can recognise. Most lamps
have ten characteristics that will identify a specific lamp:
1. The type of lamp e.g. Tungsten Halogen, Metal Halide etc.
2. The configuration and size of the cap.
3. The watts of power it consumes.
4. The voltage for which it is designed to operate.
5. The shape of the lamp.
6. The lamp's diameter.
7. The length of the lamp.
8. The finish of the lamp.
9. The amount of light, or lumens, the lamp will produce.
10. The life expectancy of the lamp.
