Solaraluma Flex 1664 Solar Flood Light
Complete Setup Guide
Everything you need to mount, connect, and configure your solar flood light — panel to pole — in under 20 minutes. No electrician. No wiring. No permit required anywhere in the U.S.
📦 What's in the Box
Before you start, lay everything out on a flat surface and confirm all 6 items are present. Nothing extra to order — everything you need for a complete installation ships in the box.
📡 The 16ft Detachable Panel — Why It Changes Everything
Most solar flood lights lock the panel directly to the light head. If your barn wall faces north, your workshop is shaded, or you need the light inside the stall — you're forced to choose between coverage and charging. Not here.
The Solaraluma Flex 1664 connects the panel to the light with a 16.4-foot (5-meter) weatherproof DC cable. Mount the panel in full sun on the south face of your barn roof. Run the cable around the corner or through a small drilled hole. Mount the light exactly where you need it — inside the barn, on a shaded north wall, above the workshop door, or in a horse stall. No compromise. That's a fundamental design difference that makes this light work where others don't.
- Panel faces south in full sun
- Light mounts inside barn or on shaded wall
- 16.4ft cable routes around corners
- Optimal charge and optimal coverage
- Works on any wall facing
- Panel and light locked to same surface
- North-facing wall = dead battery by midnight
- Shaded walls lose 60–80% of charge
- Interior barn use is impossible
- Forced to sacrifice placement for sun
⚠️ Before You Start — Read This First
- Never connect this unit to 220V AC or any household current. It will permanently damage the light and may cause electric shock or fire.
- Mount only on solid, permanent surfaces — walls, timber posts, steel poles. The bracket must not flex or shift in wind.
- Do not open or disassemble the light housing or solar panel frame (unless replacing the battery yourself). Doing so voids the 2-year warranty immediately.
- Clean the solar panel regularly. Dust, pollen, and bird droppings reduce charging efficiency by up to 30% — especially in dry ranch and desert environments.
The LiFePO4 battery ships at a partial charge for transport safety. Before the first night of use, place the panel in direct sunlight for one full day (6–8 hours). This pre-charges the 24Ah battery to full capacity and guarantees all-night brightness from night one. Skipping this step is the most common reason the light goes out early on its first night.
What You'll Need (Not in the Box)
- Drill with appropriate bit for your surface (masonry, wood, or metal)
- Phillips head screwdriver
- Pencil or marker (for marking hole positions)
- Ladder suited for 10–16ft working height
- Tape measure or level (optional — helps with alignment)
🔧 Step-by-Step Installation
Follow these steps in order. Most property owners finish in under 20 minutes. You'll need your drill and the included hardware — nothing else.
Unbox and Identify All 6 Parts
Lay everything out on a flat surface. Confirm you have: solar panel, flood light head, DC cable, wall bracket, hardware pack, and remote. Check that the DC cable connector matches the port on the flood light — the connectors are keyed and only fit one way. Do not force the connection.
Connect the DC Cable (Panel → Flood Light)
Align the waterproof connector from the solar panel cable to the port on the flood light. Match the flat orientation guides before pushing in, then twist clockwise to lock. A secure connection shows no gap at the collar. This is the only "wiring" in the entire install — and it's completely tool-free.
Choose Your Mounting Locations
Flood Light Location: Select the wall, barn door frame, post, or interior surface where you need light coverage. Recommended mounting height: 10–16 feet (3–5 meters). Higher = wider coverage radius. Lower = more concentrated brightness on a smaller zone.
Solar Panel Location: The panel needs unobstructed direct sunlight — no overhangs, tree branches, or structures casting shade. South-facing at a 35° tilt is optimal for most U.S. locations. You have 16.4 feet of cable to work with — the panel doesn't need to be on the same wall or even the same side of the building.
Mark and Drill Mounting Holes
Hold the mounting bracket against the wall at your target height. Use the bracket holes as a template and mark your drill points with a pencil. Drill tip by surface type:
- Concrete or masonry: Use a masonry bit and the included anchors
- Wood post or timber: Drive screws directly — no anchor needed
- Metal surface: Pre-drill with a metal bit, then use the included screws
Attach the Mounting Bracket
Drive the included screws through the bracket into your drilled holes. Once mounted, pull firmly — it should not flex, shift, or wiggle at all. This bracket carries the flood light through wind, rain, and ice loads. Pre-adjust the bracket angle before attaching the light so it points toward your target coverage zone.
Hang the Flood Light Head
Slide the flood light head onto the mounted bracket and secure with the included bolts. Aim the beam toward your coverage area — a 30–45° downward tilt from vertical works well for most driveway and gate applications. Tighten all bolts fully. The IP66 housing handles any weather condition once locked.
Mount and Angle the Solar Panel
Mount the solar panel bracket at your sun-facing location. Important: the solar panel must be positioned above or at the same height as the flood light — this prevents water from pooling at the cable connection point. Route the DC cable along the wall edge using cable clips for a clean, wind-resistant run. Refer to the Panel Angle Guide in Part 2 for optimal tilt by U.S. region.
First-Time Activation — Press AUTO
With the panel connected and in sunlight, point the remote at the flood light and press the AUTO button. This activates optical/dusk-to-dawn mode — the recommended setting for daily use. The light will turn on automatically every evening at dusk and off at sunrise, every single night, with no further action needed.
☀️ Solar Panel Placement & Angle Guide
Panel angle is the #1 factor that determines all-night runtime. Getting this wrong costs you 25–50% of daily charge — meaning your light may dim or go out before dawn.
100% charging efficiency. Ideal for most U.S. latitudes. Start here.
~75% efficiency. Flat-roof mounts lose significant output, especially in winter.
~50% efficiency. Too steep — especially in summer when the sun tracks high.
• Northern Tier (MT, WY, ND, MN, ID): Increase tilt to 40–45° from December through February for better winter sun angle
• Southern Tier (TX, AZ, FL, NM): 25–30° works well year-round — sun stays high
• Pacific Northwest (OR, WA): Use 5H or 8H timer mode during Nov–Feb to stretch battery reserve through low-sun stretches
• All regions: Avoid any partial shading — even 20% shade on the panel can cut output by more than 50%
🌈 3 Color Temperatures — Pick the Right One
Switch color modes anytime using the WW/CW/NW button on the remote. No tools, no ladder. Here's when each setting works best:
Soft, amber-tinted light. Creates a welcoming, relaxed atmosphere without harsh glare. Ideal for patios, porches, landscaped entries, and anywhere you entertain guests after dark.
Clean, balanced light — closest to natural afternoon sun. Maximizes visibility without harshness. The everyday setting most ranch and property owners use for driveways and gates.
Crisp, high-contrast light that mimics clear midday sunlight. Maximum visual clarity for tasks, work areas, and security. Preferred by barn owners doing nighttime chores.
🎮 Remote Control — Every Button Explained
One remote handles everything. No app. No WiFi. No Bluetooth pairing. Point it at the light from the ground, press once, done — even after installation at 12 feet.

🧹 Maintenance & Long-Term Care
- Clean the solar panel every 4–6 weeks with a damp cloth. In dry, dusty ranch and farm environments, a coating of dust and pollen can reduce daily charge by up to 30% — directly shortening your overnight runtime.
- Inspect the DC cable connection twice a year (spring and fall) to confirm it's fully seated and sealed. Check after any severe storm or high-wind event. A partially loose connector is the most common cause of unexplained dim performance.
- Adjust panel tilt angle seasonally in northern states. Re-tilting your panel to 40–45° from December through February can recover meaningful charge capacity as the sun drops lower on the horizon. Takes five minutes with a screwdriver.
- Battery replacement is a DIY job when the time comes — typically 8–12 years from installation. The front-frame access panel opens without special tools. Swap the 24Ah LiFePO4 cell and you're back to full original performance. No need to replace the whole unit.
- If the light starts dimming earlier in the night: clean the panel first, then check the DC cable connection. If the issue persists, contact our Wyoming team at info@solaraluma.com — we respond within 1 business day.
