Product Overview

The ProLED MR16 Series from Halco Lighting Technologies is a line of low-voltage LED reflector lamps built to replace 10W, 20W, 35W, and 50W halogen MR16 lamps. The 81061 occupies the 4W position in that line and is rated by the manufacturer as a 20W halogen equivalent. All lamps in the series share a GU5.3 bi-pin base, an 82 CRI rating, a 40,000-hour useful life rating, and a 2.00-inch maximum diameter with a 1.97-inch maximum overall length, so they drop into standard MR16 sockets without changing fixture geometry.

This particular version is configured for 60-degree wide flood distribution at 2700K warm white, delivering 300 lumens with a center beam candlepower of 210. Halco specifies a 10–18V input range for this wattage tier, which is intended to give installers tolerance for voltage drop across longer low-voltage runs rather than forcing a strict 12V feed at the socket. Halco notes energy savings of up to 87% for the series, based on $0.11 per kWh over a 25,000-hour life.

The lamp is dimmable to 5%, though Halco states that it may not be compatible with all dimming systems and that dimming performance varies by system. Magnetic transformers are recommended for dimming applications, and the lamp may not be compatible with all electronic transformers. Halco also notes that these lamps are acceptable for use in sealed metal landscape fixtures when protected from the elements, and that the lamp can be used in Sollos fixtures.

Compatible Applications

• Landscape lighting — path, accent, and specimen fixtures using GU5.3 MR16 sockets
• Accent and display lighting in residential and commercial interiors
• Retail merchandise and showcase lighting
• Replacement for 20W halogen MR16 lamps in existing low-voltage fixtures
• Sollos landscape lighting fixtures
• Sealed metal landscape fixtures where the lamp is protected from the elements
• Systems supplying 10–18V at the lamp, including runs with meaningful voltage drop

Before Ordering – Verify

• Confirm the fixture uses a GU5.3 bi-pin base. GU10 twist-lock and GU4/MR11 bi-pin sockets will not accept this lamp.
• Confirm the supply voltage at the lamp falls within 10–18V. This wattage tier is rated for that range, and other tiers in the ProLED MR16 series use a different range.
• Confirm the beam spread. This lamp is 60° wide flood; the series is also offered in 20° narrow flood, 40° flood, and 60° wide flood versions.
• Confirm the color temperature. This lamp is 2700K; other options in the series include 2700K, 3000K, and on selected wattages 5000K.
• Verify transformer type. Magnetic transformers are recommended for dimming; the lamp may not be compatible with all electronic transformers.
• Verify dimmer compatibility by testing in the actual application before committing to a full installation, since dimming performance varies by system.
• Confirm the fixture is not an enclosed fixture, which is outside the manufacturer’s rated use.
• Confirm the fixture location is dry or damp, not wet, unless the lamp is inside a sealed metal landscape fixture that protects it from the elements.

Safety and Handling Guidelines

• Disconnect power to the fixture or transformer before installing or replacing the lamp.
• Allow the existing lamp to cool before removal, particularly when replacing halogen lamps.
• Handle by the lamp body; avoid applying force to the GU5.3 pins during insertion or removal.
• Seat the pins fully and squarely in the socket to avoid arcing or intermittent operation.
• Do not install in enclosed fixtures, where trapped heat can shorten LED and driver life.
• Do not operate the lamp outside its rated input voltage range.
• Inspect landscape fixture gaskets and lenses so the lamp remains protected from moisture.
• Installation should follow all applicable national and local electrical codes.

Compliance

• UL listed for damp locations
• 82 CRI per the manufacturer’s published ordering information
• Useful life rated to 40,000 hours at 70% lumen maintenance (L70)
• 5-year commercial/industrial limited warranty from date of purchase, based on 10 hours of use per day
• 20-year lamp warranty when the lamp is installed in Sollos fixtures
• Specifications per Halco Lighting Technologies ProLED MR16 Series documentation; all sizes and specifications are subject to change by the manufacturer
