6. Improvement Recommendations

1 Upgrade to LED Fixtures

Replace fluorescent T8 fixtures with LED equivalents providing similar light output at 50% lower power consumption.

Expected Benefits:

• 50% energy savings ($630/year)
• 50,000+ hour lifespan
• Instant-on performance
• Better light quality (CRI 80+)

Recommended Specs:

• 4ft LED tubes, 18W each
• 2200 lumens per fixture
• 4000K color temperature
• Dimmable 0-10V

ROI: Payback period of 18-24 months with energy savings alone

2 Optimize Fixture Layout

Current fixture spacing may be causing uneven light distribution. Consider:

Spacing Recommendations:

• Mounting height: 12-15 ft
• Spacing: 1.5x mounting height
• Aisle lighting: 1.2x spacing
• Perimeter: closer spacing

Potential Impact:

• 15-20% better uniformity
• Eliminate dark spots
• Reduce glare issues
• Improve task lighting

3 Implement Controls

Add occupancy sensors and daylight harvesting to reduce energy use during unoccupied periods and utilize natural light.

Recommended Controls:

• Motion sensors in low-traffic areas
• Daylight sensors near windows
• Time-based scheduling
• Wireless control system

Energy Savings:

• 20-30% additional savings
• $250-375 annual reduction
• 6-12 month payback
• Easy installation
