Lighting a 20-Ft Flagpole: Fixture Selection & Dark-Sky Compliance

You want to illuminate a 20-ft residential flagpole. A 50W halogen flood is the big-box option. Is it enough?

Short Answer: No.

50W at 20 ft delivers ~5–8 foot-candles at the flag—barely visible. Flag code requires "proper illumination." Most pros use 120–150W metal halide or LED equivalents (15–25W LED) with narrow-beam optics (15–25°).

Where to Buy Real Flagpole Lights

• AmericanFlagstore.com – fixtures to 250W, direct consumer.
• Commercial lines: Hadco, Unique, Greenlee, LSI, King Luminaire, Nightscape, Focus, Vista.
• Search manufacturer name + "flagpole light" for spec sheets and distributors.

Critical Check: Local Ordinances

Many municipalities have "dark sky" laws limiting uplight, spill, or wattage. HOAs often restrict fixture type. Verify before buying.

Mounting

• Ground-mounted, 3–4 ft from pole base, aimed up.
• Two fixtures at 90° separation = even coverage.
• Use photocell + timer: dusk to 11 PM (or per local code).

Don't cheap out. A proper fixture costs $150–300 and lasts 15+ years. The flag deserves it.
