| Nominal
Voltage |
Type
of tension the lamp is intended to be used for i.e. 6v, 12v,
24v |
| Test
Voltage |
Exact
tension the lamps was designed to develop its best performance
at i.e. 6.75v, 13.2v, 28v |
| Flux |
Amount
of light going out of the lamp in all directions |
| Lumen
Maintenance |
Ratio
of light output of new lamp/old lamp measured after 75% (Tc)
of specified lifetime expressed as percentage of initial flux |
| Lifetime |
Time
that elapses until the filament breaks and the lamp emits no
more light (B3=3% Tc=63.2% lamps that fail) |
