Product Overview

MR16 lamps are reflector lamps: a small tungsten halogen capsule sits at the focus of a dichroic reflector that collects and directs the light into a defined beam. Because the whole optical system is contained in a two-inch lamp, MR16 remains the standard source for display, accent, and retail lighting where a small aperture and a precisely controlled beam matter more than raw output.

This lamp is part of GE's MR16 Start range of 12V halogen reflector lamps. It is an open face lamp with no integral cover glass, so it must be installed in a fixture fitted with a lens or protective shield.

Beam angle is the specification that most often determines which order code is correct, because centerbeam intensity changes substantially with beam spread at the same wattage. Other versions of this 50W 12V open MR16 Start lamp: item 39874 (24° beam, 2,700 cd). Voltage matters equally: this is a 12V lamp and requires a matching low-voltage supply.

Before Ordering — Verify

Confirm the beam required. This lamp is the 36° version at 1,500 cd. Other versions in the same 50W 12V group are item 39874 (24° beam, 2,700 cd).
Confirm the socket is GU5.3 two-pin. GU5.3, GX5.3, and GU7 Turn & Lock are not interchangeable, and a lamp with the wrong base will not seat or retain correctly.
Confirm the supply is 12V and that the transformer is rated for 50W per lamp across the total lamp count.
This is an open face lamp with no cover glass. Confirm the fixture has a lens or protective shield. Do not install in an unshielded fixture.
Confirm the fixture accepts an MR16 lamp with a 47.6 mm overall length.
Confirm pack quantity — the manufacturer pack quantity for this order code is 20.
ANSI code EXN can be used to cross-reference equivalents from other manufacturers. Confirm cover glass, base, and voltage as well, since the ANSI code alone does not distinguish them.
Specifications are taken from GE's European lamp catalogue (Spectrum). Confirm suitability for your installation and local requirements.

Safety and Handling Guidelines

Disconnect power and allow the lamp to cool completely before handling or replacement. Halogen lamps run hot and stay hot well after switch-off.
Do not touch the capsule or reflector with bare hands. Skin oils cause localized overheating and can lead to premature failure. Clean with isopropyl alcohol if the glass is touched.
Handle the lamp by its reflector body or base, not the capsule.
This lamp has no cover glass. Install only in a fixture fitted with a lens or protective shield so that fragments are contained if the capsule fails.
Operate on a 12V supply only. Overvoltage operation sharply reduces lamp life.
Do not install a lamp with a cracked, scratched, or otherwise damaged reflector.
Keep combustible materials clear of the lamp and fixture.
Follow the fixture manufacturer's instructions for lamp orientation and any position restrictions.
This lamp contains no mercury. Recycle or dispose of it in accordance with local requirements.

Compliance

Refer to the warning and caution notices published by GE for this order code before specification or installation.
Contains no mercury. Not subject to mercury lamp disposal or shipping restrictions.
Dispose of in accordance with local regulations.
