How To Choose Best Flood Light For Outdoors

1. Einleitung

Flood light delivers wide, even illumination across large areas. With beam angles up to 180°, it suits various outdoor needs. But with so many options available, choosing the right one can be tricky. This guide helps you pick the best flood light for outdoors based on key specs and real-world scenarios.

2. Buyer’s Guide

Brightness and luminous flux (Lumens - lm):

Importance: Directly determines the range and intensity of lighting. Wattage (W) only represents power consumption, while luminous flux (lm) is the true outdoor led flood light brightness indicator.

Selection suggestions:

Small area lighting (courtyard, porch): 1000 – 3000 lm
Medium area (single lamp post in parking lot, basketball court): 5000 – 15000 lm
Large area (football field, industrial area): > 20000 lm (usually requires a combination of multiple lamps)

Abstrahlwinkel:

Importance: Determines the shape and range of light coverage. The larger the angle, the wider the coverage but the lower the central brightness; the smaller the angle, the more concentrated the light.

Selection suggestions:

Large area uniform lighting (squares, courtyards): Choose a wide beam angle (90° – 120° or larger).
Mid-distance accent lighting (building facades, parking lots): Choose a medium beam angle (60° – 90°).
Long-distance projection (stadiums, high mast lights, airports): Choose a narrow beam angle (15° – 30°).

Color Temperature - Kelvin - K:

Importance: Affects visual perception and environmental atmosphere.

Common range:

Warm white light (2700K – 3000K): Warm and comfortable, suitable for residential courtyards and hotel landscapes.
Neutral white light (4000K – 4500K): Natural and clear, most commonly used in parking lots, roads, and sports fields (taking into account both recognition and comfort).
Cool white light (5000K – 6500K): Bright and sharp, suitable for industrial areas that require high alertness, large-scale sports events, and security monitoring areas. Note: Cool white light may increase the sense of light pollution.

Color Rendering Index (CRI):

Importance: Indicates the ability of a light source to restore the true color of an object. The higher the CRI (maximum 100), the more realistic the color.

Selection suggestions:

Security monitoring, parking lot: ≥ 70 (need to clearly identify license plates, faces, and object colors).
Stadiums, commercial outdoor flood lights: ≥ 80 (ensure accurate colors of athletes and products).
High-end landscape lighting: ≥ 90** (restore the true colors of plants and building materials).

Ingress Protection - IP Rating:

Importance: Key indicator of dust and water resistance. Outdoor lights must have a high IP rating. All our flood lights are waterproof outdoor led flood lights.

Interpretation: `IPXX` (the first digit is dustproof, the second digit is waterproof).

Recommended/harsh environments:

Minimum requirement: IP65 (completely dustproof and protected against low-pressure water jets).
Heavy rain, coastal salt spray areas: IP66 (protected against strong water jets) / IP67 (protected against short-term immersion).
Dusty construction sites, sandstorm areas: the first digit is ≥6.
Underwater or long-term water spray: IP68 (water depth and time must be specified).

Material and heat dissipation:

Shell material: Die-cast aluminum is the best choice (good heat dissipation, high strength, corrosion resistance). Avoid cheap plastics.

Heat dissipation design: Fin-type heat sink is the mainstream. Poor heat dissipation is the main reason for the shortened life of LED lights! We have professional Hochtemperatur-Flutlicht.

Energy efficiency and lifespan:

Luminous efficacy (lm/W): The higher the value, the more energy-efficient it is. High-quality outdoor led flood light usually have a luminous efficacy of 100-150 lm/W or more.

Rated lifespan : Select a nominal lifespan of ≥ 50,000 hours and based on the L70/B10 standard (70% of the lights maintain more than 70% brightness after 50,000 hours). Note: High temperatures will significantly shorten the lifespan.

Dimming and smart control:

Dimming function: Does it support 0-10V/DALI/PWM/thyristor dimming methods? Is it necessary to provide Outdoor flood light fixtures motion sensor dimmable.

Intelligent control: Is it necessary to connect sensors (human body, light sensitivity), timers or intelligent systems?

6. People also ask

Can I replace the outdoor led flood light with a regular LED light?

Strongly not recommended! Ordinary LED lights will quickly break down (water ingress/short circuit/light decay) outdoors, and even cause safety hazards. You must choose professional waterproof outdoor LED flood lights. And ordinary LED lights do not have the lighting effect of outdoor LED flood lights.

Do your LED flood lights consume a lot of electricity?

Compared with traditional lamps, it saves energy significantly, but the power selection needs to be reasonable. The luminous efficiency of LED is 150 lumens/watt, which is more energy-saving than sodium lamps (about 100 lumens/watt) and halogen lamps (about 20 lumens/watt).

How far will a 200W LED flood light reach?

The irradiation distance depends on the beam angle, not the power alone!

200W narrow beam light (30°) illuminates the court: the football is visible from 50 meters away

200W wide beam light (120°) illuminates the parking lot: covers 4 parking spaces (approximately 15 meters x 15 meters)

How far does 20,000 LED flood light lumens shine?

Lumens determine the total brightness, and the irradiation distance is still dominated by the optical design (beam angle)!

Narrow beam (20°): concentrated light spot, maximum range 60 meters + (such as football field corner flag area lighting)

Wide beam (120°): light diffusion, effective distance is only 10-15 meters (such as square ground lighting)

Zum Beispiel:

Need to illuminate the stadium 30 meters away: choose 20000 lumens + narrow beam (30°)
Need to cover 100㎡ warehouse floor: choose **20000 lumens + wide beam (120°) + installation height 6-8 meters
