Model identification and verified starting point

Portfolio WLL103BZ is the Wren Hill integrated-LED outdoor wall lantern, item 1085711. The manual lists it for wet locations and states total fixture wattage of 7.8 watts. The LED is integrated and the manual says not to attempt to replace it.

This guide separates documented model facts from practical troubleshooting. Where the surviving documentation does not establish a component value, proprietary part number or interchangeability claim, the page does not guess. Use the physical label on your fixture or power pack as the final authority for the unit in front of you.

Confirm WLL103BZ before buying anything

WLL103BZ is easy to confuse with other bronze Portfolio wall lanterns because the useful identifier is on the fixture label, not the architectural style. Keep model WLL103BZ and item 1085711 together in your notes.

The manual also covers related WLL104BZ, but that does not make every part interchangeable. WLL103BZ is the 7.8-watt integrated-LED version documented here. Photograph the label before the fixture comes off the wall; once a discontinued lantern is removed, that label may be the only reliable way to search for an exact used fixture or compatible replacement.

The most important repair fact: there is no normal bulb to change

The manual explicitly says not to attempt to replace the LED. That changes the troubleshooting logic. When the lantern is dark, removing the lens and shopping for a screw-in bulb is the wrong first move.

First determine whether the fixture is receiving correct line power and whether the wiring connections are sound. If power is present and the integrated LED/driver assembly has failed, replacement of the complete fixture is usually more realistic than a lamp change. Do not substitute an undocumented LED board simply because it physically fits.

Completely dark versus flickering versus dim

A completely dark WLL103BZ can result from loss of branch-circuit power, a loose splice, a failed integrated driver/LED assembly or a fixture-level connection problem. Flicker points more strongly toward an intermittent connection or failing electronic driver.

A fixture that has become noticeably dim while neighboring lights remain normal deserves comparison at the same time of night and with the same circuit conditions. Diagnose the symptom at the fixture before assuming a whole-house voltage problem.

A safe wiring check tells you more than random parts swapping

This is a 120V hardwired wall fixture. De-energize the circuit at the breaker and verify the work area is safe before touching conductors.

Inspect the junction-box connections, grounding conductor, wire connectors and mounting arrangement. Look for a conductor that was pinched behind the mounting strap or a splice that loosened as the fixture was tightened to the wall. If you are not comfortable working on line-voltage wiring, this is the point to use a qualified electrician rather than experimenting on an energized fixture.

Moisture does not automatically mean the fixture was never wet-rated

The manual identifies WLL103BZ for wet locations, but wet-location approval does not make installation details irrelevant. Water can still enter through a failed wall seal, damaged enclosure, loose hardware or an opening around the junction box.

If moisture is present, determine whether it is coming through the fixture or from the wall cavity. Drying the lantern without correcting the entry path only resets the clock on the same failure.

When the light works only after tapping or moving the fixture

Intermittent operation after movement is a strong reason to inspect connections before condemning the integrated LED. With power safely off, check whether the fixture conductors and supply conductors are securely joined and whether mounting pressure is disturbing a splice.

Do not keep cycling or striking an intermittent electronic fixture; arcing or a loose line-voltage connection is a service issue, not a workaround.

Replacement strategy for a discontinued integrated-LED lantern

When the LED/driver has failed and no documented service assembly is available, match the replacement to the job rather than to the old wattage alone. Record fixture height and width, junction-box location, backplate dimensions, projection from the wall, finish, light output you actually liked and wet-location requirement.

An integrated LED replacement can be appropriate, but a fixture with a replaceable lamp may be attractive if future serviceability matters more than duplicating the original construction.

Preserving a matched pair or row of lanterns

A single WLL103BZ failure is harder when several matching lanterns remain on the house. Before replacing one with a visibly different design, search the exact model and item number for old stock or a sound used fixture, while recognizing that age and unknown history matter.

If an exact match cannot be found, homeowners often get a better visual result by replacing a symmetrical pair and keeping the surviving original as a labeled spare for another location.

Related Portfolio research paths

The Outdoor Lighting hub helps compare wall-fixture problems, the Model Parts Directory keeps exact identifiers together, and the Discontinued Portfolio Lighting archive is useful when the goal is to preserve a matched exterior set. Use the electrical-code and safety guide for installation requirements rather than treating a model guide as a substitute for local code.

A five-minute evidence check before you remove the lantern

Before loosening the decorative nuts, take a few photographs in daylight and at night. Photograph the backplate against the wall, the light pattern, any condensation, the label, and the relationship between the fixture and the junction box. Then note whether other lights on the same circuit are operating normally. If the WLL103BZ is the only dark fixture, that evidence keeps the investigation local.

If several fixtures on the circuit are affected, stop treating the lantern as the only suspect. After power is safely disconnected, inspect whether the wall opening is protected from water and whether the mounting strap holds the fixture squarely. Save the old fixture until the replacement has been installed and tested; its backplate, wire length, mounting-hole spacing and finish are useful references when a replacement description is incomplete. This approach also prevents a common mistake with discontinued lighting: throwing away the only exact physical sample before confirming that the new lantern covers the old wall marks and fits the existing box.

Use Model 00742 as the Exact Record for This 300W Power Pack

For a whole-system outage, pair this exact-model record with Transformer Troubleshooting. If the controls respond but the yard stays dark, use Transformer Not Powering Lights. Preserve the 00742/item 0534701 identity while checking the Model Parts Directory so a generic power-pack page does not replace exact-model evidence.
