GE 79233 Q35MR16HIR/CCG55 — Precise™ ConstantColor™ MR16 IR 35W 12V Halogen Reflector Lamp, GU5.3 Base, Wide Flood 55°, 1000 cd

The GE Q35MR16HIR/CCG55 (product code 79233) is a 35W 12V MR16 halogen infrared reflector lamp from the Precise™ ConstantColor™ MR16 IR family, with a GU5.3 two-pin base and a dichroic mirror reflector. It produces a 55° wide flood beam at 1000 candelas peak beam intensity, with a colour temperature of 2950K and a rated life of 5,000 hours — 2.5 times longer than a standard MR16. The IR capsule carries multiple layers of durable interference film that redirect radiated heat back onto the filament, giving up to 43% energy savings against a conventional MR16 at equivalent output. The CCG designation indicates an integral cover glass, and UV control reduces fading and discolouration of lit merchandise. The lamp measures 50.7 mm in diameter by 50.5 mm long and is supplied 20 per case. Confirm the beam angle, base, and transformer rating before ordering.

Technical Specifications

Product Overview

Incandescent and halogen lamps lose approximately 76 percent of their input energy as radiated heat and convert only about 8 percent into useful light. The Precise IR halogen capsule addresses that directly: multiple layers of very durable, thin interference film on the capsule redirect infrared energy back onto the filament instead of letting it escape. Because the filament is partly heated by recycled energy, less electrical power is needed to hold it at operating temperature, which is how these lamps deliver up to 43 percent energy savings against a conventional MR16 at comparable output.

Two consequences follow that matter in practice. The beam runs cooler, because the infrared that would otherwise travel forward with the light is returned to the capsule — useful when lighting heat sensitive merchandise, food displays, or artwork. And rated life is 5,000 hours, two and a half times that of a standard MR16, which cuts relamping labour in high fixture-count installations such as retail ceilings and hospitality spaces.

GE's patented reflector coating technology gives this range its ConstantColor designation: colour rendering holds steady across the life of the lamp rather than drifting as the reflector ages, so a lamp replaced in year three still matches its neighbours. UV control reduces fading and discolouration of lit fabrics, packaging, and artwork. The dichroic mirror reflector passes heat rearward through the reflector rather than forward into the beam.

This product code is the 55° wide flood at 1000 cd. Beam spread is the specification that most often decides which code is correct, because peak beam intensity changes dramatically with beam angle at the same wattage — within the 35W group here, output ranges across item 77904 (Narrow Spot 10°, 12000 cd), item 77905 (Narrow Flood 24°, 4200 cd), item 77906 (Flood 36°, 2000 cd). The CCG suffix indicates the closed cover glass version, which contains fragments if the capsule fails and allows use in fixtures without a separate lens.

Compatible Applications

• Retail display and merchandise accent lighting
• Track lighting and adjustable low voltage downlights
• Lighting heat sensitive merchandise, food display, and artwork (cool beam)
• Museum, gallery, and exhibit casework where UV control matters
• Hospitality, restaurant, and hotel accent lighting
• Residential accent and architectural lighting
• High fixture-count installations where the 5,000 hour life reduces relamping labour
• 12V low voltage lighting systems with a matching transformer
• Fixtures without a separate lens, where a closed cover glass lamp is required

Before Ordering — Verify

• Confirm the beam spread required. This lamp is the 55° wide flood at 1000 cd. Other beams in the 35W group are item 77904 (Narrow Spot 10°, 12000 cd), item 77905 (Narrow Flood 24°, 4200 cd), item 77906 (Flood 36°, 2000 cd).
• Confirm the wattage. The same 55° beam is also offered as .
• Confirm the socket is GU5.3 two-pin. GU5.3, GX5.3, and GU7 Turn & Lock are not interchangeable.
• Confirm the supply is 12V and that the transformer is rated for 35W per lamp across the total lamp count. Note that an IR lamp draws its rated wattage even though it delivers the output of a higher wattage standard lamp — size the transformer to 35W, not to the lamp it replaces.
• Confirm the fixture accepts a 50.7 mm diameter by 50.5 mm long MR16.
• This is the CCG closed cover glass version. If the fixture already has a lens, an open front lamp may be specified instead.
• 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 pack quantity — the manufacturer pack quantity for this code is 20.
• When cross-referencing, use the GE product code rather than the description. GE lists several similar 35W codes in this family — 77906 (CCG36), 77911, 79017 (both CG35CD), and 79233 (CCG55) — that differ in beam angle and construction.
• Refer to GE's warning and caution notices for this lamp before installation.

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.
• Seat the lamp fully in the GU5.3 socket. A partially seated lamp can arc at the pins.
• 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 product code before specification or installation.
• Contains no mercury. Not subject to mercury lamp disposal or shipping restrictions.
• UV control reduces ultraviolet output, limiting fading and discolouration of lit materials.
• Dispose of in accordance with local regulations.
