The lamp
The MAC 2000 Wash comes with a double-ended lamp
installed. This is one of two models:
• Up to the middle of 2004 the lamp will be an OSRAM HMI
1200 W/S discharge lamp.
• During 2004 the Philips MSI 1200 discharge lamp will be
phased into being supplied with the MAC 2000 Wash.
The lamps are both high-efficiency short-arc sources
providing an exceptionally stable 6000K color temperature,
respective color rendering indexes of 90 (OSRAM) and 85
(Philips), and an average life of 750 hours.
Both lamps are capable of hot restrike.
The ends of the lamp have specially developed keys, as
shown in Figure 10, to ensure proper installation.
Note:
Do not use OSRAM HMI 1200 W/S lamps with the
non-keyed SFc 10-4 base.
Warning!
Installing any other lamp may create a safety
hazard or damage the fixture!
The lamp has an average life of 750 hours. To reduce the
risk of explosion, replace the lamp before usage exceeds
125% of the average life, i.e., before it exceeds 940 hours.
To read lamp hours from the control panel, please refer to
"Readouts" on page 13.
For optimum performance, avoid turning off the lamp
before it has warmed up fully.
