Product Overview
The 31621-6 (ENH) is a low-voltage halogen lamp from Philips' Photo Projection Lamps line, built for precise, repeatable output in projection, photographic, and instrument applications. It is rated for bdth burning position and a 175-hour average life at 120V.
Photo projection lamps are precision-manufactured to tight filament and envelope tolerances so that beam pattern and color are consistent from lamp to lamp; always confirm the ANSI/type code and voltage against your equipment's original lamp specification before ordering, as many lamps in this family share similar bases and wattages across different voltages.
Compatible Applications
- Slide, movie, and overhead projectors
- Microscope and instrument illumination
- Photographic and audiovisual equipment
- Medical, dental, and scientific instrument lighting
- Retrofit replacement in fixtures originally specified for this ANSI/type code
Before Ordering – Verify
- Confirm the ANSI/type code (ENH) and voltage (120V) against your equipment's original lamp specification — this lamp family includes many similar-looking lamps that share a base and wattage but differ in voltage.
- Confirm base type (GV5.3) and bulb shape (MR16) match your equipment's lamp socket/reflector.
- Confirm burning position (BDTH) is compatible with your fixture's mounting orientation.
Safety and Handling Guidelines
- Turn power off before inspection, installation, or removal of the lamp.
- Allow the lamp to cool completely before handling or relamping — these lamps operate at high filament and envelope temperature.
- Do not touch the bulb envelope with bare hands; oils can cause premature failure and hot spots. Handle by the base wherever possible.
- Do not use the lamp if the outer glass is scratched or broken.
- Do not exceed rated voltage; overvoltaging shortens life and increases the risk of premature failure.
Compliance
- Dispose of/recycle according to federal, state, and local regulations for lamp components.
- Confirm ANSI/type code ENH matches your equipment documentation before installation.
