What’s Included in the Box

Unboxing the 48-pack revealed excellent industrial-grade packaging: reinforced pallets with corner protectors and individually boxed panels. Each panel includes:

• 1 x Sunco 2×4 LED flat panel with integrated driver
• 4 x T-bar mounting clips (pre-installed)
• 1 x Quick-start guide with wiring diagram

Notably absent are junction boxes or dimmer switches—these require separate purchase. Build quality exceeded expectations; matte-finish steel frames showed zero warping, and the polycarbonate lenses had flawless optical clarity.

Installation & Usage Guide

Step 1: Pre-Installation Configuration

Using the recessed DIP switches inside each panel’s wiring compartment:

1. Select desired CCT (1=4000K, 2=5000K, 3=6000K)
2. Choose wattage mode (A=50W, B=40W, C=30W)
3. Set dimming protocol to 0-10V (Factory default)

Step 2: Drop Ceiling Installation

1. Turn off circuit breaker
2. Remove existing fluorescent fixtures
3. Position Sunco panel in T-grid, securing with 4 clips
4. Connect black/red dimming wires if applicable
5. Wire nut live (brown), neutral (blue), ground (green-yellow) cables

Step 3: Advanced Dimming Setup

When using 0-10V controls like the Lutron Hi-Lume ballast:

1. Trace dimmer’s purple (signal+) and gray (signal-) wires
2. Connect to panel’s red and black dimming wires respectively

Step 4: Zone Grouping Strategies

Group panels by department (e.g., 5000K/50W in packing stations, 4000K/40W in office areas). For advanced automation, pair with occupancy sensors.

Performance Testing Results

Brightness & Uniformity

Using a Klein Tools LT85 light meter at 10′ height:

• 50W Mode: 812 lux center → 755 lux corners (93% uniformity) > exceeds IES standards
• 40W Mode: 623 lux average with 4% color deviation

No flicker detected via high-speed camera tests—crucial for reducing eye strain during 8-hour shifts.

Energy Efficiency

Week-long monitoring with an Emporia Vue showed:

• 50W mode: 12.2kWh/day for 48 panels vs 23kWh with old T8 fluorescents
• Annual savings projection: $1,872 (at $0.14/kWh)

Thermal Performance

After 8 hours at 50W mode:

• Hottest point: 111°F (lens center)
• No thermal throttling observed versus competitors’ 15% output drop

Pros and Cons Analysis

Advantages

Frequently Asked Questions

Is Sunco 48-Pack worth buying over DIY LED kits?

Yes—pre-assembled panels offer standardized performance crucial for commercial spaces. DIY solutions often vary in color quality between fixtures.

How does Sunco compare to Litetronics L2 series?

Sunco matches L2 series’ 6500LM output but at 28% lower cost with triple the CCT options. Litetronics has better UL Type-C rating though.

What dimmers work best?

Universal 0-10V controllers like the Enlighted D70 ensure smooth light ramping per Circadian standards.

Can I install these in suspended ceilings without grids?

No—T-bar mounting clips require standard 15/16″ grid systems. For hard ceilings, consider surface-mount conversion kits.

What’s the shipment weight/dimensions?

400 lbs total—delivered on pallets via freight carrier. Requires 48″ x 48″ dock space for unloading.
