• For sports lighting applications, Life & Reliability is key. Most of the installations have a limited number of burning hours per year, though during these hours a very limited failure-rate is acceptable
Introduction
• A few lamp-manufacturers offer 2000W Short Arc lamps, though the majority has a very short lifetime, meaning very high Costs of Ownership :
- frequent high exchange costs- frequent hassle / dark spots
and…… lack of confidence that the installation will perform properly during the match to come……
Introduction
• Philips set a target to come up with a lamp:1. Having the best lifetime and reliability as offered by
benchmark competition, while…..2. Having the same mechanical and electrical
specifications as benchmark competition
• From June 2004 onwards, this lamp is available and known as:
MHN-SB Pro 2000W 400V 956 Long Life
Introduction
• The naming ‘SB’, Short Base, clearly expresses the Shorter outer-dimensions of the new lamp compared to the well-known existing Master MHN-SA 2000W lamps

Extensive laboratory tests and OEM customer feedback learnt that Osram lamps have an average lifetime of less than 1000 hrs (!)
Competition Benchmark – Beam Control
Beam Control Philips - Osram:
• The electrode distance of our MHN-SB Pro 2000W Long Life is 25.8 mm, as this distance is 34.1 mm for the Osram HQI-TS 2000W D/S
• The shorter electrode distance of the Philips lamp allows OEM’s to save appr. 15% in the number of systems to be used to illuminate a stadium

Practical Advice
• Luminaires need to be properly designed for the very high temperatures in these 2000 W systems. This is valid for all kind of 2000 W lamps available in the market
• Luminaires which are not designed properly, will get polluted. This results in the need for regular cleaning of the entire luminaire. Polluted luminaires will result in shorter lamp-life

Annex: Lifetime Master MHN-SA/LA versus MHN-SB Pro Long Life
Master MHN-SA 2000W
MHN-SB Pro 2000W Long Life
• MHN-SB Pro lifetime is ‘guaranteed’ till 1500 hrs, but will be extended in future (limited burning hrs in lab. so far)
• Because of the ‘double pinch’ technology, Master MHN-SA/LA will always have a better lifetime-performance than the ‘single pinch’ MHN-SB Pro
• The Master MHN-LA has been specially developed to have an extremely long life (12.000 hrs > 50% survivals)
