The GL-BL300 features IP66 rated rugged outdoor ready design and beam angle options including 70 and 120 degree lenses.
The large aspheric lens is designed to give a superior homogeneous light beam over the total beam angle.
A beam angle of 120 degree gives a uniform light distribution across the luminaire and delivers better illumination to the surroundings.
The sharply focused microwave beam angle ensures safe and reliable measurements without any interfering signals even in narrow tanks with baffles.
In conjunction, the scanning beam technology eliminates the time-consuming need to manually insert separate shaping accessories for each beam angle in order to match the beam to the shape of the tumor, concluded the company.
On fixed-mount cap lamps, the beam angle is permanent because neither the bracket on the helmet nor the clip on the headpiece has a mechanism to adjust the angle.
The LEDs' 40-by10 deg beam angle provides subtle illumination, while the fixtures' placement-- approximately 30 cm (1 ft) away from the foliage and flush with the top of a glass encasement--keeps the sources out of sight.
Producing up to 450 lumens with a 300-degree beam angle, the lamp provides uniform light distribution.
