Halco 81074 ProLED PAR36 4.5W Waterproof LED Lamp – 10–15V, 2700K, 300 Lumens, 32° Wide Flood, IP67

Halco ProLED® 81074 PAR36WFL4/827/IP67/LED – 4.5W PAR36 Waterproof LED | 300 lm | 2700K | IP67 | 10–15V | Replaces 20W Halogen

The Halco ProLED® 81074 (PAR36WFL4/827/IP67/LED) is a 4.5W low-voltage LED PAR36 lamp with an IP67 waterproof rating, delivering 300 lumens at 2700K (Warm White) with 82 CRI and a 32° wide flood beam. Operating on 10–15V through a multi-purpose terminal base compatible with both slip-on and screw terminal connections, it replaces a 20W halogen PAR36 and is engineered for outdoor landscape and well-light applications where waterproof reliability is required. Please verify specifications below before ordering.

Technical Specifications

Product Overview

The Halco ProLED® 81074 is a 4.5W low-voltage LED PAR36 lamp built around an IP67 waterproof rating, making it one of the most durable PAR36 landscape lamps available for well-light and outdoor accent applications. IP67 certifies the lamp against temporary immersion up to 3.28ft (1m), protecting installations where water infiltration in well lights or ground-level fixtures would otherwise cause premature lamp failure and costly maintenance callbacks.

At 300 lumens and 2700K with an 82 CRI, the 81074 delivers warm, accurate-rendering light well-suited for landscape uplighting, architectural accent, and outdoor feature illumination. The 32° wide flood beam provides broad coverage without sacrificing punch, and the 700 center beam candlepower figure gives a useful benchmark for calculating illumination at target distances. The multi-purpose terminal base accommodates both slip-on and screw terminal connections for compatibility with a wide range of low-voltage landscape fixture wiring styles.

With a 40,000-hour L70 useful life and a 5-year limited warranty, the 81074 is engineered for contractor-grade reliability. Sibling models 81075 (6.5W/35W equiv./450 lm) and 81076 (12.5W/50W equiv./800 lm) are also available in the same IP67 PAR36 family for higher-output applications.

Compatible Applications

• Landscape well lights and in-ground uplight fixtures
• Outdoor accent and architectural feature lighting
• Low-voltage 10–15V landscape transformer systems
• Residential and commercial outdoor landscape lighting
• Any PAR36 MP-Term fixture application requiring IP67 waterproof lamp protection

Before Ordering – Verify

• This lamp operates at 10–15V (low voltage); it is not compatible with 120V line-voltage PAR36 fixtures — confirm transformer output voltage before ordering
• Base type is MP Term (multi-purpose terminal); confirm the fixture accepts slip-on or screw terminal PAR36 connections, not a GU5.3 or other bi-pin socket
• If higher output is required, confirm whether 81075 (6.5W, 35W equiv., 450 lm) or 81076 (12.5W, 50W equiv., 800 lm) better match the application
• IP67 rating covers temporary immersion to 1m depth — for continuous submersion applications, this rating may not be sufficient; consult Halco for guidance
• Account for voltage drop on long low-voltage cable runs; confirm transformer output at the fixture end stays within the 10–15V input range

Safety and Handling Guidelines

• Disconnect the low-voltage transformer from line power before installing or removing the lamp
• The MP-Term base accommodates both slip-on and screw terminal connections; ensure the chosen connection method is mechanically secure and insulated against moisture
• Do not exceed the fixture’s maximum lamp wattage rating
• Allow the lamp to cool before handling if recently in use
• Dispose of in accordance with local electronics recycling regulations; this lamp contains no mercury

Compliance

• IP67 Waterproof — protected against temporary immersion between 5.9″ (15cm) and 3.28ft (1m)
• RoHS Compliant
• No mercury, no UV or IR emissions
• Mercury-free (no state shipping restrictions)
