BEAM ANGLES

25˚ A narrow beam angle ideal for illuminating specific areas of interest with pin 60˚ This wider beam angle allows for greater spacing between fittings, up
points of light. to 1.8m apart, or greater illumination at 1.2m spacings, meaning fewer
luminaires are required. Also produces a more even spread of light at floor
