What does the flashing LOAD icon mean on a Paradise transformer?

A flashing LOAD icon indicates the transformer is overloaded — total fixture wattage exceeds 100% of rated capacity. The transformer auto-shuts down at 120% overload. Disconnect fixtures until the LOAD icon stops flashing. Keep total wattage at or below 80% of rated capacity.

Can I use a Paradise transformer without a photocell?

Yes. Sunwise mode uses your geographic zone and the current date to calculate dusk without a photocell. It can be installed indoors or behind shrubs. Only AUTO mode requires the photocell. ON, OFF, and TIMER modes also require no photocell.

Paradise Landscape Lighting Transformer Troubleshooting: Every Model, Every Fix

Q: Why won't my Paradise GL33120 turn on after I set Sunwise mode?

Sunwise mode only activates at its calculated dusk time. If today's dusk has already passed when you finish programming, the transformer will not activate until tomorrow's dusk. Switch to ON mode to verify the system works, then return to Sunwise. Also verify current time and date are set using MODE plus ENTER simultaneously.

Paradise Transformer Models: Specs, Brand History, and Compatibility

Paradise Garden Lighting transformers have been sold under multiple brand names across a corporate ownership chain. Southwire previously owned the brand. In February 2021, Southwire divested the Moonrays intellectual property (a sister brand) to Fusion Products LTD, headquartered in Cambridge, Ontario. Paradise transformers appear on Amazon and in retail as both "Paradise" and "Sterno Home" — these are the same product line with the same model numbers and the same official manual (ManualsLib document 1296511 for the GL33120).

Model	Capacity	Output	All 5 Modes	Photocell	Sunwise	Install
GL33050	50W	12V AC	Yes	AUTO mode only	Yes — 3 zones	Indoor or outdoor
GL33120	120W	12V AC	Yes	AUTO mode only	Yes — 3 zones	Indoor or outdoor
GL33300	300W	12V AC	Yes	AUTO mode only	Yes — 3 zones	Indoor or outdoor
GL33600	600W	12V AC	Yes	AUTO mode only	Yes — 3 zones	Outdoor recommended

All models share the same LCD interface, button layout, and five operating modes. Scroll right on smaller screens if columns are cut off.

All Paradise transformer models output 12V AC — the universal standard for consumer low-voltage landscape lighting. This means Paradise transformers are fully compatible with Portfolio, Malibu, Hampton Bay, Moonrays, and virtually all consumer 12V landscape fixtures. The wire connection format uses a screw-terminal block inside the front panel. For full cross-brand compatibility details, see the brand connector compatibility guide. For how Paradise compares to other brands in the consumer and mid-tier market, see the low-voltage landscape lighting brand comparison.

The 5 Paradise Operating Modes — What Each One Does and When to Use It

Every Paradise transformer problem starts with identifying the current mode on the LCD display. A transformer in OFF mode looks identical to a failed transformer until you check the screen. These five modes govern all transformer operation.

ON — Always On

Fixtures powered continuously, 24 hours a day. No photocell or timer active. The correct mode for testing: if lights work in ON mode but fail in AUTO or SUNWISE, the transformer and wiring are functional and the problem is mode configuration, not hardware. Compatible with indoor and outdoor installation.

OFF — Always Off

Transformer is locked off. This is the most frequently misdiagnosed "failure" mode — accidental button press changes the transformer to OFF and the entire system goes dark. Before assuming any hardware failure, verify the display does not show OFF. Cycling the MODE button restores operation immediately if OFF was the cause.

TIMER — Fixed On/Off Times

User-programmed start and end times that do not adjust with seasons. Critical behavior documented in the official manual: Timer mode only activates at its exact programmed start time. If you set the start time to 7 PM and it is currently 8 PM, the timer will not activate until 7 PM the following day. Requires correct current time and date to be set first. No photocell needed.

AUTO — Photocell Dusk-to-Dawn

Uses the external photocell sensor to activate at dusk and deactivate at dawn or a set end time. Requires the photocell to be mounted in a location that receives direct sky light — cannot be installed behind shrubs, under overhangs, or inside a garage. If AUTO activates during daylight, the photocell is reading a shaded area as dark. Switch to SUNWISE mode to eliminate photocell dependence.

SUNWISE — Astronomical Timer

Calculates local dusk and dawn using your geographic zone (NORTH/CENTRAL/SOUTH) and the current date. No photocell required. Adjusts automatically for seasonal daylight changes — activates earlier in winter, later in summer, without any reprogramming. Can be installed anywhere, including indoors and behind dense landscaping. Requires correct time/date setting AND correct zone selection to work accurately. The most powerful mode and the most setup-sensitive.

✓ Mode Selection Guide Testing system function: use ON. Indoor install without photocell access: use SUNWISE. Photocell available and correctly positioned: use AUTO. Fixed schedule that never changes: use TIMER. System completely off during a season: use OFF. For almost all permanent landscape lighting installations, SUNWISE is the optimal mode — it provides dusk-to-dawn operation without photocell dependence and adjusts automatically to seasonal changes.

The LOAD Icon: What Every Display State Means

The Paradise LCD display includes a five-segment LOAD bar that shows real-time power consumption as a percentage of the transformer's rated capacity. It is the most important diagnostic indicator on the unit — and the one most homeowners ignore until a problem occurs.

LOAD Icon State	What It Indicates	Correct Response
0% — empty	No load detected. Mode may be OFF, no fixtures connected, or wire connections are not making contact at terminals.	Check mode setting. Open front panel and verify wire connections are clamped securely under terminal screws.
Less than 20%	Normal — low load, well within capacity. Healthy for the transformer.	No action. Adequate headroom for additional fixtures if desired.
20%–99%	Normal operating range. Optimal operation is 60–80% of capacity.	No action. System operating as designed.
Flashing / blinking	OVERLOAD — total fixture wattage exceeds 100% of rated capacity. Transformer is stressed and at risk of thermal shutdown.	Disconnect fixture runs from terminals one at a time until LOAD stops flashing. Use the transformer sizing guide to verify correct sizing. Keep load at or below 80% of rated capacity.
Auto-shutdown (all dark)	CRITICAL OVERLOAD — load exceeded 120% of rated capacity and the internal protection circuit shut the transformer down.	Unplug transformer. Wait 5 minutes. Reconnect with significantly reduced fixture load. If transformer shuts down immediately with no fixtures connected, a short circuit in the wire runs is likely — see step 3 of the diagnostic sequence below.

Scroll right on smaller screens if the table extends beyond the viewport.

⚠ Overload vs Short Circuit — Do Not Confuse These An overloaded transformer (flashing LOAD icon) recovers when fixtures are removed. A short-circuited transformer shuts down even with no fixtures connected. To distinguish: disconnect all wire runs from the transformer terminals and plug in. A healthy transformer reads LOAD at 0% with nothing connected. A transformer that shuts down with no load connected either has an internal fault or the short is in the cord connecting it to the outlet. See the GFCI tripping and ground fault guide for zone isolation to find a short in buried wire runs.

Sunwise Astronomical Timer: Complete Setup and Fix Guide

Sunwise is the feature that makes Paradise transformers genuinely distinctive in the consumer landscape lighting market. It is also the feature that generates the most setup errors. This section covers exactly how Sunwise works, the three geographic zones, the mandatory two-step setup sequence, and every documented failure mode.

How Sunwise Calculates Dusk and Dawn

Sunwise uses a three-zone geographic classification of the continental United States combined with the current date and time to mathematically estimate local sunset and sunrise. No photocell is needed because the transformer is not reading sky light — it is computing when sky light should end based on your latitude band and the time of year. As the seasons progress, the calculated dusk time automatically shifts: later in summer, earlier in winter. A landscape lighting system set to Sunwise mode in March will automatically turn on later at night by June with no user intervention.

The Three Sunwise Geographic Zones

NORTH Zone

All locations north of Chicago, Illinois. Also the correct selection for all Canadian locations. If you are in the northern tier of the United States — Minnesota, Wisconsin, Michigan, New England, the Pacific Northwest — select NORTH. Selecting the wrong zone produces lights that activate significantly too early or too late relative to actual local dusk.

CENTRAL Zone

Locations between Chicago, Illinois and southern Missouri. This covers a broad swath of the central and mid-Atlantic United States. If you are uncertain between NORTH and CENTRAL, CENTRAL is the correct default for most of the continental interior. Kansas City, Indianapolis, Columbus, and similar cities fall in CENTRAL.

SOUTH Zone

All locations south of Missouri. Covers the American South, Southwest, Texas, and Florida. If lights consistently activate earlier than actual local dusk, try switching from CENTRAL to SOUTH. Per the official manual: at extreme northern or southern latitudes, Sunwise accuracy may be limited and a different mode may be preferable.

The Mandatory Two-Step Sunwise Setup Sequence

Both steps must be completed before Sunwise will operate correctly. The official manual states explicitly: "This step is needed for the lighting modes Auto, Timer and Sunwise to work properly or else they won't open/close at the right time."

Step 1 — Set current time and date:

MODE + ENTER simultaneously

Press MODE and ENTER at the same time. The display will enter time/date setting mode. Use the UP and DOWN arrows to select values. Press ENTER to confirm each value. Set date first, then time. Without this step, Sunwise cannot calculate the correct dusk time for your location and date.

Step 2 — Set Sunwise geographic zone:

MODE + UP simultaneously

Press MODE and UP at the same time. Select NORTH, CENTRAL, or SOUTH based on your location. Press ENTER to confirm. This setting persists after power loss — you do not need to reset it unless you move the transformer to a different geographic location.

Step 3 — Select SUNWISE mode: Press MODE alone to cycle through modes until SUNWISE appears on the display.

Step 4 — Set end time: Choose between DAWN (automatic, recommended) and a fixed end time. To select DAWN, scroll UP/DOWN during end-time selection until the DAWN icon (sunrise symbol) appears on the display, then press ENTER. DAWN end time adjusts automatically with the seasons — the lights turn off later in summer and earlier in winter.

Common Sunwise Failures and Their Causes

Symptom	Cause (From Official Manual)	Fix
Sunwise set but nothing happened	Mode was programmed after today's dusk. "Timer and Sunwise mode only open up at their exact start time setting (Start for timer and dusk for Sunwise)."	Switch to ON mode to verify the system works. Wait until tomorrow's dusk, or reset the clock to a slightly earlier time temporarily.
Significant delay vs actual local dusk	Wrong geographic zone selected. "Make sure that you selected the right zone."	Access zone setting (MODE + UP) and try the next zone south. Repeat if needed.
Sunwise not optimal at all	Extreme latitude. "If you live far to the north, or far to the south, Sunwise may not be optimal."	Use TIMER mode with manually set times, adjusting seasonally. Or use AUTO mode with correctly positioned photocell.
Lights stay on past dawn	DAWN end time not selected — fixed end time was set instead.	Re-enter end time setting, scroll until DAWN icon appears, press ENTER to select it.
Sunwise stopped working after power outage	Current time and date were lost. Sunwise cannot calculate dusk without correct date.	Re-enter time and date (MODE + ENTER), then verify SUNWISE is still the selected mode.

Scroll right on smaller screens.

Every "my Paradise transformer stopped working in Sunwise mode" case I have investigated resolved at one of two points: either the mode was set after that day's dusk had already passed (lights come on the next evening and the homeowner thinks the transformer mysteriously fixed itself overnight), or the time and date were never set before Sunwise was selected. The official manual is explicit about both issues but neither is mentioned in any consumer-facing FAQ or retailer support documentation. The fastest diagnostic: switch to ON mode. If lights come on immediately, Sunwise was a configuration issue, not a hardware failure.

Complete Paradise Transformer Troubleshooting — 7 Steps in Order

Work through these steps in sequence. Skipping to a later step wastes time — approximately 70% of reported Paradise transformer failures resolve at steps 1 through 3.

Read the LCD display — is the mode set to OFF?

An accidental press of MODE can cycle the transformer into OFF mode, producing complete system darkness that looks identical to a failed transformer. Check the display. If it shows OFF, press MODE to cycle to ON and verify lights activate. This resolves roughly 20% of apparent Paradise failures instantly. Also verify the display is powered — if the LCD is completely dark with the unit plugged in, the outlet has no power.

Switch to ON mode — do lights activate?

Press MODE until ON appears. If lights activate immediately in ON mode, the transformer and all wiring are functional. Return to the Sunwise setup guide above and reprogram the astronomical timer. If lights do not activate in ON mode, the problem is not a timer configuration issue — proceed to step 3. This step isolates whether the problem is in the transformer/wiring or in the mode configuration.

Reset the GFCI outlet

Locate the GFCI outlet the Paradise transformer plugs into. Press the RESET button on the outlet face. If the system activates after reset, a ground fault in the landscape wiring tripped the GFCI. Use the zone isolation procedure in the GFCI tripping guide to identify which wire run contains the fault. A GFCI that trips immediately after reset has an active ground fault that must be located and repaired before normal operation resumes.

Check the LOAD icon — is it flashing?

A flashing LOAD icon confirms overload. Disconnect landscape wire runs from the transformer terminals one at a time. Monitor the LOAD icon after each disconnection. When the icon stops flashing, the last disconnected run was pushing the system over capacity. Calculate total fixture wattage on all remaining connected runs and verify it is at or below 80% of the transformer's rated capacity (96W for GL33120, 240W for GL33300, 480W for GL33600). See the transformer size calculator.

Check wire connections at the terminal block

Open the front panel by pulling the right side below the LCD screen. Inspect each screw terminal — each landscape wire conductor should be clamped firmly under its screw with no bare copper exposed outside the terminal. Loose connections produce complete system failure or intermittent operation. Re-strip wire ends (remove 0.5 inches / 12.7mm of insulation), twist copper strands, reinsert, and tighten the terminal screw firmly. Pull on each wire to confirm it cannot be removed by hand. See the landscape lighting connectors guide.

Diagnose dim far-end fixtures — voltage drop

If fixtures near the transformer are bright but fixtures at the far end of wire runs are dim or flickering, voltage drop across the wire run is the cause. Paradise transformers output 12V AC with no adjustable voltage tap (unlike some Hampton Bay models that offer a 15V tap). Options: reposition the transformer closer to the fixtures, replace 16AWG wire with 12AWG for long runs, or add a second transformer at a different point in the system. See the voltage drop guide and the minimizing voltage drop guide.

Measure output voltage with a multimeter

Set multimeter to AC voltage (20V range). Touch probes to the output terminals with transformer in ON mode. A functional Paradise transformer reads 11.5V to 12.5V with no load. Below 10V indicates internal degradation. 0V with the GFCI and outlet verified working indicates complete internal failure. See how to test a landscape lighting transformer. If output voltage is 0V in ON mode with a verified working outlet, the transformer has failed internally and requires replacement.

When to Replace Your Paradise Transformer

A Paradise transformer that reads 0V output in ON mode with a verified working GFCI outlet has failed internally and is not serviceable. Paradise transformers have no user-accessible internal components or fuses that can be replaced at home.

Any standard 12V AC landscape lighting transformer is a compatible replacement. Your existing wire runs and fixtures connect without modification — only the terminal wire connections need to be transferred. If you valued the Sunwise astronomical timer feature, the Hampton Bay Hubspace 200W smart transformer provides a comparable astronomical timer function with additional WiFi and app control. For standard dusk-to-dawn operation without smart features, the Hampton Bay SL-120-12A (120W) or SL-200-12A (200W) are the most widely available current-production equivalents. For complete replacement guidance see the Hampton Bay transformer replacement guide and the transformer replacement guide.

For selecting a replacement based on your system's total wattage, see the transformer sizing guide. For understanding what other brands are available at similar and higher price points, see the brand comparison guide.

Paradise Transformer Troubleshooting FAQ

Why won't my Paradise GL33120 turn on after I set Sunwise mode?

Sunwise mode only activates at the calculated local dusk time for your geographic zone. If today's dusk has already passed when you finish programming, the system will not activate until the following evening's dusk — this is documented behavior, not a malfunction. Switch to ON mode to immediately verify the transformer and fixtures are working. If they are, return to Sunwise and wait until tomorrow evening. Also verify the current time and date are correctly set using the MODE+ENTER button combination.

What does the flashing LOAD icon mean on my Paradise transformer?

A flashing LOAD icon means the total wattage of connected fixtures exceeds 100% of the transformer's rated capacity. The GL33120 shuts down automatically at 120% overload. Disconnect fixture runs from the terminal block one at a time until the LOAD icon stops flashing. Keep total connected wattage at or below 80% of rated capacity — 96W maximum for the GL33120, 240W for the GL33300. See the transformer size calculator.

Can I use a Paradise transformer without the photocell?

Yes — Sunwise mode operates entirely without a photocell. It uses your geographic zone setting (NORTH/CENTRAL/SOUTH) and the current date to calculate dusk and dawn. You can install a Paradise transformer in a garage, basement, or behind dense landscaping in Sunwise mode and it will operate on the correct schedule. Only AUTO mode requires the photocell. ON, OFF, and TIMER modes also require no photocell.

My Paradise transformer worked fine and suddenly went completely dark — what happened?

Four most common causes in order of frequency: (1) mode accidentally changed to OFF — check the LCD display first; (2) GFCI outlet tripped from a ground fault in landscape wiring — reset the GFCI outlet; (3) overload protection activated from a wiring short or new fixture added that pushed load over 120% — check LOAD icon; (4) power outage caused Sunwise mode to lose its time/date setting and the mode defaulted incorrectly. Switch to ON mode as the first diagnostic step.

Are Paradise transformers compatible with Portfolio, Malibu, and Hampton Bay fixtures?

Yes. All Paradise GL-series transformers output 12V AC, which is the universal standard for consumer low-voltage landscape fixtures. Portfolio, Malibu, Hampton Bay, Moonrays, and generic consumer 12V fixtures are all compatible. The screw terminal connection at the Paradise transformer accepts standard 14AWG and 12AWG landscape wire used by all consumer brands. See the connector compatibility guide for details on cross-brand connections.
