The luminous efficacy of the 60W LED lamp is 150 lumens per watt (lm/W), and the total luminous flux of the 60W LED lamp is approximately 6000 - 9000 lumens.

Actual irradiation effect at 60W: Under the standard configuration of an installation height of 8 meters and a spacing of 25-30 meters, the average illuminance on the road surface can reach 15-25 lux (National Road Lighting Standard: the illuminance for secondary roads is 10-15 lux, and for branch roads it is 8-10 lux).

It can clearly illuminate a 2-lane road (about 7 meters wide), and the outlines of pedestrians, vehicles, and road obstacles (such as potholes and stones) can be identified, with no obvious lighting blind spots.

60W + 5000K combination: The road surface at night presents a bright and refreshing white light, allowing the colors of electric vehicles and pedestrians' clothing to be clearly identified, thereby enhancing traffic safety.

Lighting design for 60W lamps
Bat-wing type lighting: Light spreads to both sides, suitable for wide roads (such as 6-8 meter roads), with high edge illumination.

Narrow-angle lighting: Light is concentrated downward, suitable for high pole lamps or scenarios requiring long-distance projection (such as squares, parking lots).

60W street lamp case: Under the same power, street lamps with professional lighting design can increase the uniformity of road illumination from 0.3 to 0.6 (the closer the uniformity is to 1, the better the lighting effect).

The 60W LED street lamp can provide bright and uniform lighting at night, suitable for most urban side roads, rural roads and small and medium-sized parks. It can not only meet the traffic safety requirements but also take into account energy conservation and economy. The actual effect needs to be comprehensively evaluated based on the installation height, spacing and light distribution design to avoid resource waste caused by insufficient power or excessive lighting.
