Sylvania 37MR16/IR/FL35/C #58633

Sylvania 58633 37MR16/IR/FL35/C — TRU-AIM® IR MR16 37W 12V Halogen Infrared Reflector Lamp, GU5.3 Base, 35° Flood, 3000K, CRI 100

The Sylvania TRU-AIM® IR 37MR16/IR/FL35/C (item number 58633) is a 37W 12V low-voltage tungsten halogen MR16 reflector lamp with infrared reflective coating on the capsule. It uses a GU5.3 bi-pin base, produces a 35° flood beam at 2200 centerbeam candlepower, and delivers 3000K light at CRI 100 with an average rated life of 5,000 hours. The lamp combines a UV-control capsule with the IR coating to eliminate UV-B and UV-C radiation, and uses a hard coated dichroic reflector that holds its color point across the life of the lamp rather than shifting. An axial filament produces an exceptionally smooth beam pattern, and the lamp is supplied with a clear cover glass for use in unshielded fixtures. Maximum overall length is 1.750 in with a 2 in reflector diameter. Confirm the beam angle, base, and fixture ventilation before ordering.

Technical Specifications

Measured Operating Temperatures (37W)

Temperatures were measured in open air at 25°C (77°F) ambient using a Bender & Worth 884 socket, and are provided for reference only. Actual temperatures in a specific fixture will differ.

Product Overview

TRU-AIM IR lamps achieve their efficacy through thermal recovery. The tungsten halogen capsule is ellipsoidal and carries an infrared reflective coating, so radiated heat that would otherwise be lost is reflected back onto the filament. Because that heat is recycled inside the capsule, less electrical energy is needed to bring the filament to its operating temperature — which is how a 37W lamp reaches the centerbeam output that a higher wattage standard dichroic MR16 would require. Sylvania's own comparison places this lamp at 2200 cd against a competing 50W flood lamp at 1700 cd.

The filament is axially aligned between the focal points of the ellipsoidal capsule, with a return lead wire routed back down the center of the filament to optimize infrared reflection without interfering photometrically. Xenon fill gas in the burner further raises luminous intensity and efficacy. The practical result is an exceptionally smooth beam pattern without the striations or hot spots a transverse filament can produce.

Two features matter for merchandise and artwork. The hard coated dichroic reflector holds its color point across the life of the lamp instead of drifting, so a display relamped in year three still matches one relamped in year one — and lamps in adjacent fixtures match each other. The UV-control capsule combined with the IR coating eliminates UV-B and UV-C radiation, which reduces fading on UV-sensitive merchandise, textiles, and artwork. Together with a color rendering index of 100, that makes this lamp a common specification for retail display, galleries, and museum casework.

This lamp is supplied with a clear cover glass, which is what the /C suffix denotes and what makes it suitable for unshielded fixtures where an uncovered MR16 would not be permitted. Average rated life is 5,000 hours.

Compatible Applications

• Highlighting merchandise and retail display lighting
• Accent and display lighting in track and adjustable downlight fixtures
• Highlighting heat sensitive merchandise
• Art galleries and museum casework, where UV control and color consistency matter
• Hotels and restaurants
• Decorative room lighting and ambient lighting
• Case lighting strips and display cabinetry
• Landscape lighting fixtures on 12V systems
• Unshielded fixtures requiring a covered lamp
• Energy-saving replacement for a higher wattage standard dichroic MR16 flood

Before Ordering — Verify

• Confirm the beam spread required. This lamp is the 35° flood (FL). Other beam angles in the 37W TRU-AIM IR family are narrow spot 10° (item 58641, 12,500 cd), narrow flood 25° (item 58634, 4400 cd), and wide flood 60° (item 58837, 1100 cd). Centerbeam candlepower changes substantially with beam angle.
• Confirm the wattage tier. The same 35° flood is also made in 20W (item 58533, 1000 cd) and 50W (item 54173, 2850 cd).
• Confirm the socket is GU5.3 bi-pin with 1/4 in maximum pin spacing. GU5.3 is not interchangeable with GU10 or other MR16 base types.
• Confirm the fixture is supplied by a 12V transformer or low-voltage supply. This lamp will not operate on line voltage.
• Confirm the transformer capacity accommodates 37W per lamp across the total lamp count.
• Confirm the fixture accepts a 2 in diameter MR16 with a 1.750 in maximum overall length, including the cover glass.
• Confirm whether a covered lamp is required. This item includes a clear cover glass; uncovered versions of TRU-AIM IR lamps are separate order codes.
• Confirm fixture ventilation around the lamp neck. Infrared conserving capsules run hotter than standard halogen capsules of the same wattage because the recycled heat passes through the capsule glass twice.
• Confirm case quantity — this item is supplied 20 per case.

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 glass 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.
• Ensure adequate ventilation around the lamp neck. Infrared conserving halogen capsules operate at a higher temperature than standard halogen capsules of the same wattage, and restricted airflow at the neck shortens lamp life.
• Do not install in a fixture or socket that inhibits air flow in the neck area.
• 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 or cover glass.
• 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.
