GE 28709 Q20MR16/HIR/CG10 — Precise™ Cover Glass IR MR16 20W 12V MR16 Halogen Reflector Lamp, GU5.3 Base, Narrow Spot

The GE Q20MR16/HIR/CG10 (order code 28709) is a 20W 12V MR16 tungsten halogen reflector lamp from the Precise™ Cover Glass IR MR16 family, with a GU5.3 two-pin base and a C-8 filament. It produces a narrow spot beam at 6000 centerbeam candlepower. Initial color temperature is 3000K and rated life is 5000 hours. Maximum overall length is 1.88 in. This is an HIR lamp — the capsule carries an infrared reflective coating that returns radiated heat to the filament, so the lamp reaches the output of a higher wattage standard halogen MR16 while drawing less power. The lamp includes a cover glass, which contains fragments if the capsule fails and permits use in fixtures without a separate lens. 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 Precise Cover Glass IR range. The halogen capsule carries an infrared reflective coating that reflects radiated heat back onto the filament instead of letting it escape. Because that heat is recycled, less electrical energy is required to hold the filament at its operating temperature — which is how a 20W IR lamp delivers centerbeam intensity comparable to a higher wattage standard halogen MR16. Rated life is 5000 hours, substantially longer than the 2,000 hours of GE's standard MR16 range.

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 20W 12V group within this family are item 28710 (Narrow Flood, 2300 cd), item 28718 (Flood, 1000 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 without a separate lens, where a covered lamp is required

Before Ordering — Verify

• Confirm the beam required. This lamp is the narrow spot at 6000 cd. Other beams in the same 20W 12V group are item 28710 (Narrow Flood, 2300 cd), item 28718 (Flood, 1000 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 20W per lamp across the total lamp count.
• This lamp includes an integral cover glass. If the fixture already has a lens, an open face lamp may be specified instead.
• Confirm the fixture accepts an MR16 with a 1.88 in maximum overall length.
• Confirm fixture ventilation around the lamp neck. Infrared coated capsules run hotter than standard halogen capsules of the same wattage because the recycled heat crosses the capsule glass twice.
• Confirm case quantity — the manufacturer case quantity for this order code is 20.
• 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.
• Do not install a lamp whose cover glass is cracked, chipped, or missing. The cover glass provides fragment containment.
• Ensure adequate ventilation around the lamp neck. Infrared coated capsules operate at a higher temperature than standard halogen capsules of the same wattage, and restricted airflow shortens lamp life.
• 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.
