Portfolio Lighting Master Model Technical Database: Specs, Parts and Compatibility Index

Quick Answer: How This Database Helps

This page helps identify what a Portfolio model is, what electrical system it belongs to, what usually fails, and what replacement direction makes sense. That matters because many older Portfolio products are searched by Lowe's item number, not by the model number printed on the transformer, fixture sticker, or original package.

Use this database with the Portfolio Lighting model number lookup, the model specs guide, and the model parts directory when you need a deeper repair path.

If your model number points to an older discontinued fixture, start with the discontinued Portfolio Lighting guide so you can understand whether the product is still serviceable, parts-only, or better replaced with a compatible modern fixture.

The master model database should treat Cooper Portfolio architectural LED products differently from simple retail model numbers. Long catalog strings often describe an assembled system, not one part. The Portfolio architectural LED catalog guide breaks down those configurable codes into housing, driver, LED engine, trim, finish, and retrofit logic.

Logic Summary: Model, Power, Failure, Compatibility

If the transformer powers on but the lights still fail, compare the symptoms with Portfolio transformer not powering lights and Portfolio transformer getting hot before replacing the unit.

Need exact replacement parts, connector dimensions, transformer compatibility, or legacy fixture identification? Use the Portfolio Lighting Replacement Handbook before ordering replacement components or rewiring older systems.

Beyond Model Numbers: Understanding Why Fixtures Fail

A model number can identify a fixture, but it does not explain why the system stopped working. Successful repairs require understanding the relationship between transformers, wiring runs, LED drivers, connectors, photocells and fixture electronics. While this database helps identify Portfolio Lighting products and specifications, visitors troubleshooting an active failure should also review common transformer failure symptoms, use integrated LED bypass testing techniques to separate fixture failures from power-supply problems, and consider Portfolio Lighting AI diagnostic assistance for guided troubleshooting, discontinued-part matching and personalized repair recommendations.

Technical Compatibility Rules Before You Use the Model Cards

Transformer rules

Portfolio transformer compatibility starts with voltage and load. A 12V AC transformer can power compatible low-voltage landscape fixtures, but the transformer wattage must stay below practical load limits. I use the 80% rule: a 120W unit should normally be planned around 96W, a 200W unit around 160W, and a 300W unit around 240W.

For deeper transformer decisions, use the Portfolio transformer wattage guide, transformer sizing guide, transformer troubleshooting guide, and transformer wiring diagram.

Fixture rules

A socketed fixture is usually easier to repair than an integrated LED fixture. If the fixture uses a replaceable MR16, T5 wedge, candelabra, or medium-base lamp, you can often repair the light without replacing the housing. If the LED is integrated, the connector, wire lead, and driver/module condition matter more.

For fixture parts, use the Portfolio Lighting replacement parts guide, LED modules and drivers guide, and low-voltage wire connectors guide.

GL22640–GL22647 Legacy Series Note

The GL22640 through GL22647 models are treated as a Lowe's-era low-voltage transformer family. The biggest technical issue is not just wattage. It is connector compatibility. These older systems may use proprietary or older clip-on connector styles that do not match modern Portfolio replacement connectors.

The best compatibility path is usually to confirm 12V AC output, test the transformer under load, and adapt the field wiring to modern 12/2 cable with weatherproof low-voltage connectors when the old connector ecosystem is no longer practical.

Individual Portfolio Model Specification Cards

Each model below includes a legacy identity, electrical profile, housing/build note, repairability score, common failure point, compatibility mapping, and technical note. Use the button on each card to return to the master table.

Portfolio Transformer Model Deep-Dive References

The master model database is the best starting point for broad identification, but certain Portfolio transformers need their own page because wattage class, timer behavior, enclosure style, photocell logic, and terminal layout can change the correct repair decision.

Commercial model records are most useful when the individual numbers are treated as a connected assembly rather than unrelated parts. A housing may remain usable even when the driver fails, but the replacement driver must still match the LED engine’s current, voltage range, dimming method, thermal limits, and listing instructions. The Portfolio commercial lighting guide provides the system-level interpretation needed to turn database entries into a safe repair or retrofit plan.

For older black-housing power packs, the EE4859BK Portfolio low-voltage transformer reference helps compare label details, outdoor enclosure style, wiring access, and replacement clues before assuming the unit is obsolete.

If the model sticker is faded but the number appears to match 999928302, use the Portfolio 999928302 power-pack identification guide to narrow down transformer behavior, setup clues, and compatible replacement direction.

Smaller systems should be checked against the SL-100-12 Portfolio 100-watt transformer manual, especially when fixture count, total wattage, cable distance, and basic 12V output limits need to be confirmed.

For larger systems with heat, cycling, shutdown, or unstable output symptoms, the LTF300WH Portfolio 300-watt diagnostic page gives a more repair-focused path than a general model listing.

When the issue involves an older kit or part family rather than only the transformer, the Portfolio 0066580 model parts and manual lookup helps connect archived model identification with replacement parts and repair planning.

Exact Model Pages With Deeper Technical Diagnostics

The strongest model database does not just list numbers. It connects each model to the real-world failure behavior that owners see after years outdoors: moisture intrusion, broken stakes, bad sockets, connector oxidation, transformer hum, and fake voltage readings.

For exact-model support, use the SS9C-P5-BKT-CPK1 parts decoder, the 0378225 low-voltage connector guide, the 0157561 flood light troubleshooting page, the 0062582 path light repair guide, the 0805200 transformer testing guide, and the 7404280540 fixture compatibility page.

Technical databases are strongest when they show how certain each record is. Some Portfolio models have manuals and specifications, while others only have a label, receipt number, or repeated owner report. The Portfolio Lighting Lost Models Archive separates verified records from likely matches, partial matches, and models that still need owner confirmation, which makes it safer to choose replacement parts.

Each one adds model-level repair logic that is more useful than a simple manual link.

Recently Added Portfolio Fixture Model Guides

Identifying discontinued Portfolio fixtures and sourcing replacement parts is much harder when no documentation exists online. The model-specific guides below cover the most-searched discontinued Portfolio fixture item numbers — each page provides specs, parts identification, troubleshooting by symptom, and compatible replacement options for that specific model.

If you are working with outdoor wall lanterns, deck lights, or fixtures with internal circuit boards that have no available manual, these pages are the most complete resources available. Each guide also links to the broader Portfolio replacement parts library, the model number lookup, and the discontinued Portfolio lighting hub.

For the full list of discontinued Portfolio model guides including transformer-specific pages, use the discontinued Portfolio lighting hub or the model number lookup to find the guide that matches your specific item number.
