Quick Fixture Finder
Use the mounting position and light direction first. Those clues usually identify the fixture family faster than finish or decorative style.
Path and area lights
Staked fixtures with a stem and a downward-spreading head. Common failures are stakes, sockets, lenses and connectors.
Spotlights and floodlights
Aimable fixtures for trees, walls, flags and façades. Check lamp access, lens, gasket, knuckle and driver.
Deck and step lights
Surface or recessed fixtures mounted into rails, posts, stairs and hardscape. Hidden splices often fail first.
Wall lanterns and sconces
Line-voltage fixtures near doors, garages and patios. Glass and finish matching are often harder than electrical repair.
Recessed and architectural
Ceiling systems that may have separate housing, trim, reflector, LED engine, driver and emergency codes.
Solar fixtures
Battery-powered fixtures with a panel, charging circuit, switch and small LED board.
The Portfolio Fixture Identification Record
Before searching for parts, create a complete fixture record. One exterior photo is rarely enough because Portfolio reused similar shapes while changing the internal lamp, connector, stake or driver.
- Photograph the fixture installed. Include mounting position, nearby transformer or junction box and the full bracket or wire path.
- Photograph every label. Check the underside, inside the lens area, mounting plate, wire tag, transformer door, manual and original box.
- Record the electrical family. Note 120V line voltage, 12V or 15V low voltage, solar battery power or an external LED driver.
- Identify the light source. Record bulb base, lamp shape, LED module, COB board or sealed integrated engine.
- Measure the mechanical interface. Include lens dimensions, screw spacing, stake thread, bracket holes, stem diameter and gasket shape.
- Document the failure. State whether the fixture is dark, dim, flickering, wet, loose, broken, corroded or physically incomplete.
Use the Portfolio Lighting model number lookup when a label is readable. When the number has no dedicated record or the label is incomplete, use the Portfolio Lighting lost models archive.
Master Portfolio Fixture Family Matrix
| Fixture Family | Mounting | Power Type | Light Source | Common Failure | Best Identification Clue | Likely Repair |
|---|---|---|---|---|---|---|
| Path light | Ground stake and stem | Low voltage or solar | Wedge, bi-pin, module or integrated LED | Stake, water, socket | Stake thread and head profile | Stake, bulb, socket, connector or head |
| Spotlight | Stake or surface base | Low voltage | MR16, bi-pin or integrated LED | Flicker, lens, knuckle | Lamp access and aiming joint | Bulb, lens, gasket, connector or fixture |
| Floodlight | Stake, wall or eave | Low or line voltage | Halogen or integrated LED | Driver, water, bracket | Input voltage and driver label | Driver, lamp, bracket or fixture |
| Deck light | Post, rail or wall | Low voltage | Wedge, bi-pin or integrated LED | Hidden splice, screws | Faceplate and wire exit | Connector, screws, lens or fixture |
| Step light | Recessed or surface plate | Low or line voltage | Integrated LED or lamp | Moisture behind plate | Rough opening and box depth | Gasket, driver, faceplate or assembly |
| Wall lantern | Exterior junction box | 120V | E26, candelabra or integrated LED | Glass, socket, finish | Glass geometry and backplate | Glass, socket, hardware or fixture |
| Motion light | Wall or eave box | 120V | Lamp or integrated LED | Sensor, photocell, water | Sensor and control labels | Reset, sensor, driver or fixture |
| Recessed downlight | Ceiling housing | 120V–277V or driver-fed | Lamp, retrofit or LED engine | Driver, spring, thermal issue | Housing and trim codes together | Trim, driver, engine or retrofit |

Portfolio Path Lights: Identify the Support System Before the Lamp
A path light usually includes a head, stem, internal wire, threaded collar, stake and buried connector. The support system determines whether the head can be saved.
Mechanical layer
Broken stake, stripped stem, leaning head, cracked collar or loose canopy.
Electrical layer
Failed bulb, corroded socket, broken lead, loose connector or damaged splice.
Weather-seal layer
Flattened gasket, fogged lens, water inside the head or corrosion through the wire entry.
Use the landscape lighting screw thread guide and Portfolio replacement stakes guide before ordering support hardware.
Portfolio Spotlights and Floodlights: Beam Problems Are Not Always LED Problems
When one spotlight is dim, discolored or flickering, compare it with a nearby working fixture. The cause may be voltage drop, a corroded connector, damaged MR16 socket, wet lens or loose aiming joint.
Replaceable MR16
A removable lamp means brightness, color temperature and beam angle can often be corrected without replacing the housing.
Integrated LED
A sealed board may require a matched driver or complete fixture when the engine is inaccessible.
Separate driver
Record driver input, output current, output voltage range and dimming method.
Cracked lens
A crack changes moisture protection even while the light still works.
Loose knuckle
A fixture that drops out of aim may have worn serrations or a stripped locking screw.
Color mismatch
New LEDs can be cooler, brighter or narrower-beamed than an older halogen system.
Use the replacement LED modules and drivers guide when the light source is integrated.
Deck, Step and Hardscape Fixtures: Hidden Connections Cause Visible Failures
These fixtures often look clean from the front while failing behind the mounting plate. Water can enter through screw holes, travel into cable, collect in a recessed cavity or corrode a splice hidden inside a post.
| Visible Symptom | Hidden Failure | What to Inspect | Mistake to Avoid |
|---|---|---|---|
| Flickers when plate is touched | Loose splice or pinched wire | Wire and connector strain | Replacing LED before checking splice |
| Rust streak below screw | Fastener corrosion and water path | Screw, gasket and opening | Installing a shorter random screw |
| Lens fogs after rain | Backside moisture or seal failure | Gasket compression and drainage | Sealing only the front lens |
| One post light is dead | Wire break at moving joint | Post base and cable transition | Assuming transformer failure |
| New fixture misses opening | Wrong faceplate or rough-in | Plate, screw spacing and cavity | Buying by wattage alone |
For damaged screws and brackets, use the mounting hardware and bracket replacement guide.
Portfolio Wall Lanterns and Sconces: Glass Is Often the Hardest Part to Match
Wall fixtures are frequently electrically repairable but visually difficult to restore. Standard sockets and mounting hardware may have replacement paths, while model-specific glass panels, curved shades and decorative cages disappear after discontinuation.
Measure before searching for glass
- Height, width, thickness and curvature.
- Flat, beveled, notched or rounded edges.
- Retention method: tabs, screws, clips, frame channels or top cap.
- Clear, seeded, frosted, ribbed or amber appearance.
- Number of identical panels and clearance from the bulb.
Use the Portfolio replacement lenses guide and discontinued Portfolio Lighting guide.
Recessed and Architectural Fixtures: One Installed Light Can Have Several Model Numbers
Commercial and architectural downlights should be identified as assemblies. Housing, trim, reflector, LED engine, driver and emergency accessory may each carry a separate catalog code.
| Component | What Its Code Controls | Why It Matters |
|---|---|---|
| Housing or frame | Aperture, ceiling type, thermal rating and installation | Controls physical and listing compatibility |
| Trim or reflector | Finish, beam control and opening geometry | Can fit the hole yet mismatch optics or housing |
| LED engine | Lumen package, color temperature and load | Must match driver output and thermal system |
| Driver | Input voltage, output current and dimming | Wrong current can shorten life or damage engine |
| Emergency option | Battery, transfer behavior and wiring | Cannot be removed casually from egress use |
Use the Portfolio commercial lighting guide for architectural assemblies and Portfolio recessed lighting for residential housings and retrofit modules.
Portfolio Solar Fixtures: Battery Failure Is Common, but Not the Only Failure
A dim solar light is often blamed on the rechargeable battery, but the panel, switch, charging circuit, LED board, contacts and moisture seals all matter.
Battery first
Confirm chemistry, voltage, capacity, size and terminals.
Panel second
Clean haze and check charging before blaming the LED.
Contacts third
Green or white deposits can block charging with a new battery.
Switch fourth
Small slide switches corrode and create intermittent operation.
Board fifth
Water damage can make component repair impractical.
Housing last
A failed seal can make every battery replacement temporary.
A serviceable battery compartment improves repairability. A glued, potted or permanently sealed head lowers it because inspection damages the weather seal.
The Fixture Layer Test: Find the Failed Part Before Buying Anything
Every fixture can be checked as a sequence of layers. This prevents buying a replacement head when the buried connector is the real failure.
- Power layer: confirm transformer, circuit or battery output.
- Connection layer: inspect wire nuts, pierce connectors, terminals, cord entries and local splices.
- Control layer: check photocells, sensors, timers, switches and dimmers.
- Light-source layer: test the bulb, socket, LED engine or driver independently.
- Optical layer: inspect lens, reflector, diffuser and contamination.
- Mechanical layer: verify stake, stem, bracket, knuckle and mounting stability.
- Seal layer: inspect gaskets, glass seating, screw holes and moisture tracks.
The low-voltage failure-points guide explains why a meter can show voltage while a corroded connection cannot deliver usable current.
Fixture Failure Signature Database
| Symptom | Likely Fixture Cause | System Cause to Exclude | First Test |
|---|---|---|---|
| One fixture dark | Bulb, board, socket or connector | Broken branch wire | Test at transformer or known-good point |
| Flickers when moved | Loose socket, lead or connector | Transformer relay chatter | De-energize and inspect movement points |
| Dims after rain | Water in lens, socket or driver | Wet buried splice | Inspect moisture and test voltage under load |
| New LED strobes far away | Driver below minimum voltage | Cable drop or resistance | Measure voltage with LED connected |
| Will not hold aim | Worn knuckle or screw | Soil movement or cable tension | Check joint and stake separately |
| Lens fogs but light works | Gasket or seal failure | Wire-entry moisture | Open, dry and inspect both paths |
| Socket turns green | Moisture corrosion | Recurring failed lens or lead seal | Correct water source before new lamp |
| Runs hotter than neighbors | Wrong lamp or poor contact | Overvoltage near transformer | Compare lamp, voltage and connection |
Portfolio Fixture Repairability Score
This scoring method helps decide whether a fixture deserves component repair, a donor part or complete replacement.
| Score | Construction | Parts Outlook | Typical Decision |
|---|---|---|---|
| 5 — Highly repairable | Replaceable bulb, openable housing, standard stake or bracket | Several measurable or universal parts | Repair the failed layer |
| 4 — Good candidate | Accessible socket or driver, removable lens | Parts require careful matching | Repair if housing and seals remain sound |
| 3 — Conditional | Integrated LED with accessible driver | Specs known but exact parts uncertain | Compare repair with replacement |
| 2 — Difficult | Sealed board, proprietary glass, damaged casting | Donor fixture may be only source | Replace unless appearance match is critical |
| 1 — Retire | Cracked housing, corrosion, brittle wire and failed seal | No dependable repair path | Replace fixture or zone |
Compatibility Checklist Before Replacing One Fixture
- Voltage: match 12V AC, 12V DC, multi-voltage or line voltage.
- Actual wattage: include the fixture in transformer-load and voltage-drop calculations.
- Color temperature: a new 3000K LED may look cooler than an older halogen or warm LED system.
- Brightness and beam: match usable lumens and optical distribution, not only wattage.
- Connector: replace incompatible quick-connect hardware with a proper waterproof splice.
- Mounting: confirm stake thread, bracket size, rough opening, screw spacing and weight.
- Weather exposure: the replacement must suit the actual wet, damp or sheltered location.
- Controls: verify photocell, timer, dimmer, motion and smart-control compatibility.
- Appearance: finish, lens clarity, height and nighttime beam should match neighboring fixtures.
The Portfolio Lighting compatibility guide covers cross-model matching. When an exact part is unavailable, use replacement for Portfolio landscape lighting and Portfolio Lighting alternatives.
When One Failed Fixture Signals a Larger System Problem
A single dark fixture may be local. Several fixtures failing in the same area usually point to the system around them.
Same branch fails
Look for damaged trunk cable, hidden splice, overload or shared connector.
Far fixtures dim first
Measure voltage drop and connection resistance before replacement.
Failures follow rain
Inspect low points, buried splices, cracked lenses and wire entries.
Near fixtures run hot
Check multi-tap voltage and lamp ratings.
Many stakes break
Consider aged plastic, frozen soil, impact and excessive fixture weight.
Multiple LEDs flicker
Check transformer output and high-resistance connections.
Use the Portfolio transformer master guide when several fixtures share the problem. For broad diagnosis, start with Portfolio landscape lights not working.
Not every older Portfolio fixture is considered vintage, but many discontinued fixture families deserve special restoration consideration because of their unique construction and decorative value. If your fixture appears to be an older model, the Portfolio Vintage Lighting guide explains how to estimate its age, evaluate restoration potential, and determine whether preserving the original fixture makes more sense than replacing it.
Do Not Buy a Fixture Until You Know These Five Answers
2. Is the light source replaceable or integrated?
3. What mounting interface must match?
4. What color, brightness and beam must the new fixture reproduce?
5. Is the failure inside the fixture or elsewhere in the system?
Those answers prevent the most expensive mistake: replacing a working fixture because a connector, transformer tap or buried wire was never tested.
Portfolio Lighting Fixture FAQ
Where is the model number?
Check the underside, lens compartment, mounting plate, wire tag, transformer door, manual cover and original box. A Lowe's item number may appear separately.
Can I replace only one landscape fixture?
Yes, when voltage, load, color temperature, brightness, beam, connector and mounting can be matched.
Why does a new fixture not work on an old transformer?
The fixture may require a different AC/DC supply, minimum voltage, polarity, driver architecture or connector. Voltage drop may also keep an integrated LED driver from starting.
Can broken wall-fixture glass be replaced?
Flat glass may be reproducible by a local glass shop. Curved, molded or patterned glass usually requires an exact part, donor fixture or full replacement.
How do I know whether the fixture or wire is bad?
Test a low-voltage fixture at the transformer with a short known-good lead. If it operates normally, inspect the buried run and connectors.
