GE 20833 Q50MR16C/FL40

GE 20833 Q50MR16/C/FL40 — ConstantColor® Precise™ MR16 50W 12V MR16 Halogen Reflector Lamp, GX5.3 Base, Flood, ANSI EXN

The GE Q50MR16/C/FL40 (order code 20833) is a 50W 12V MR16 tungsten halogen reflector lamp from the ConstantColor® Precise™ MR16 family, with a GX5.3 two-pin base and a C-6 filament. It produces a flood beam at 1700 centerbeam candlepower. Initial color temperature is 3050K and rated life is 6000 hours. Maximum overall length is 1.88 in. This is an open face lamp with no cover glass and must be used in a fixture with a lens or protective shield. Confirm the base type, beam angle, transformer voltage, and fixture shielding before ordering.

Technical Specifications

Product Overview

MR16 lamps are multifaceted reflector lamps: a small tungsten halogen capsule sits at the focus of a faceted reflector that collects and directs the light into a defined beam. The faceting smooths the beam and softens its edge compared with a smooth reflector. 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 ConstantColor® Precise™ range, which holds a consistent color point across the life of the lamp and from lamp to lamp. 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 description 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 beams in the same 50W 12V group within this family are item 20839 (Narrow Spot, 9100 cd), item 20835 (Narrow Flood, 3200 cd), item 20834 (Narrow Flood, 2500 cd), item 20832 (Wide Flood, 900 cd). Voltage matters equally: this is a 12V lamp and requires a matching low-voltage supply.

Compatible Applications

• Retail display and merchandise accent lighting
• Track lighting and adjustable downlights
• Museum, gallery, and exhibit casework
• Hospitality, restaurant, and hotel accent lighting
• Residential accent and decorative lighting
• Display cases and cabinetry lighting
• 12V low-voltage lighting systems with a matching transformer
• Fixtures fitted with a lens or protective shield

Before Ordering — Verify

• Confirm the beam required. This lamp is the flood at 1700 cd. Other beams in the same 50W 12V group are item 20839 (Narrow Spot, 9100 cd), item 20835 (Narrow Flood, 3200 cd), item 20834 (Narrow Flood, 2500 cd), item 20832 (Wide Flood, 900 cd).
• Confirm the socket is GX5.3 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 with a 1.88 in maximum overall length.
• Confirm case quantity — the manufacturer case 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.
• Refer to GE's warning and caution notices for this lamp before installation. The notice codes listed for this order code in the manufacturer catalog are defined in a separate section of that catalog.

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.
