MPXL DUV35 P32d 928550229400

These microdischarge lamps are hot restrike, extremely robust, offer a long service life and come with either 35 or 50 watt power ratings. The DL and RP types can be operated in fast run-up mode and emit very little UV light due to the UV blocking outer bulb. In the RP version the burner is mounted for optimal light performance in a converging 50 mm reflector. The DUV versions are unique and emit in the UV spectrum.

Application

• Portable forensic equipment
• Non-destructive testing
• Industrial fiber optics
• Aircraft landing and taxi lighting
• Marine spot and search lighting

Features

35W Microdischarge lamps with an arc length of 3.8 mm mounted on a P32d base, according IEC 61/1: 7004-111-1. They are made for radiation in the UV part of the spectrum.

Ballast/starter

These lamps can only be used in conjunction with an electronic ballast and starter. The lamp DUV 35 is not made for a ‘fast run-up mode’. Lamps can be relit right after switch-off (hot restrike). The ballast must then have sufficient starting voltage and power. Lamp voltage is approx. 85 V.

Lamp behaviour over life DUV35 Lamp life and UV output depend greatly on the type of ballast. If gently started the output in UV will be 10% lower after 500 h life. In this mode some lamps live up to 2000 h, then however with only 30% UV output. If a fast run-up ballast (automotive) is used, the lamp will only be able to make 50 starts. More precise information on lamp life can be obtained from ballast manufacturers.
