Choosing between solar flood lights and AC-powered LED flood lights is one of the most common decisions for outdoor lighting buyers. The wrong choice costs money; the right choice saves energy, simplifies installation, and improves ROI. This guide walks through the real comparison, when each option wins, and how to spec correctly.
Parameter | Solar Flood Light | AC LED Flood Light |
|---|---|---|
Power source | Solar panel + battery | Grid power (AC 110-277V) |
Installation | No wiring needed | Trenching + cable laying required |
Operating cost | $0 (free solar) | $0.05-0.20 / kWh × usage |
Upfront cost (200W fixture) | US $350-450 | US $80-150 + cabling |
Total 10-year cost (with install) | US $400-500 | US $1,200-2,500 |
Backup during outage | Continues to work | No light |
Best for | Off-grid, remote, security | Grid-connected, high-output |
Solar flood lighting is the correct choice when:
No grid access — construction sites, remote farms, rural roads, mines, oil & gas sites
Trenching is impractical — wetlands, rocky terrain, heritage sites, paved areas
Quick installation is required — emergency lighting, event venues, temporary security
Energy costs are high — remote areas with diesel generators, islands with expensive electricity
Backup lighting is critical — security perimeters, emergency exits, disaster-prone areas
Carbon footprint matters — sustainability reporting, green building certifications (LEED, BREEAM)
AC-powered LED flood lighting is the correct choice when:
Grid is reliable and cheap — most urban installations in developed countries
High lumen output is critical — stadiums, large parking lots, ports (>20,000 lumens)
24/7 operation needed — high-traffic areas where dimming is unacceptable
Tight budget on upfront cost — but willing to pay operating costs
Existing electrical infrastructure — replacement of older HID/Halogen flood lights
For projects with mixed conditions (some grid, some off-grid), hybrid solar-AC flood lights offer the best of both worlds:
AC primary, solar backup: Normal AC operation with solar+battery backup for outages
Solar primary, AC backup: Solar operation with AC backup for continuous-output scenarios
Dual-source with smart switching: Automatic switchover based on grid availability
SUNDE offers hybrid flood lights as part of OEM/ODM customization. MOQ 100 units.
Scenario | Recommendation |
|---|---|
Construction site lighting | Solar (no grid, portable) |
Stadium sports field | AC LED (high lumen, grid reliable) |
Parking lot (urban, grid) | AC LED (high hours, reliable grid) |
Parking lot (remote, no grid) | Solar |
Billboard / signage | Solar (no trenching, easy install) |
Building facade / architectural | Both viable — solar preferred for new construction |
Security perimeter (remote) | Solar (backup during outage critical) |
Industrial yard (grid) | AC LED (high output needed) |
Mine site | Solar (no grid in remote locations) |
Oil & gas platform | Solar (explosion-proof solar options) |
Event venue (temporary) | Solar (no installation needed) |
Farm / agriculture | Solar (remote, no grid) |
SUNDE manufactures solar flood lights from 50W to 400W, all OEM-customizable:
Model | Wattage | Lumens | FOB Price | Best For |

SF-100W | 100W | 17,000 lm | US $175-235 | Parking lots, security |
SF-200W | 200W | 34,000 lm | US $340-440 | Large yards, billboards, mines |
SF-300W | 300W | 51,000 lm | US $480-620 | Sports fields, industrial |
SF-400W | 400W | 68,000 lm | US $640-820 | Stadium-grade, large industrial |
All models feature IP66, LiFePO4 battery, MPPT controller, and OEM branding.
For grid-connected projects, SUNDE also manufactures AC LED flood lights with the same OEM flexibility:

Aspect | Solar Flood Light | AC LED Flood Light |
|---|---|---|
Time per light | 15-30 minutes | 2-4 hours (cabling + electrical work) |
Specialist needed | General labor | Licensed electrician |
Permit requirements | Usually none | Often required (electrical) |
Site disruption | Minimal | Significant (trenching) |
Permitting cost | Low | Medium to high |
Solar installation cost savings are often the decisive factor for new projects on developed land.
