The fixture is further designated by a W for wide beam angle.
For a narrower beam angle with higher lux and increased throw, the Tulip I Lux Enhancer accessory turns the GL-BL150 into a spotlight, great for outdoor lighting tower usage and whenever a tighter beam is desired.
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.
Another design upgrade to the product that offers innovation and differentiation over competitors was to move away from the conventional narrow beam angle (historically used in halogen lamps) that most other LED manufacturers employed towards a wider 600 beam.
Bulbrite PARs and Reflectors are designed to utilize less power resulting in energy savings while offering more beam angle options than before: Narrow Flood, Flood and Wide Flood.
They have a range of 30 in and a beam angle of 80[degrees].
The bulbs Delta is selling at 7-Eleven convenience stores feature omni-directional 270-degree beam angle, 100,000 times of on-off, two-year warranty, and Nichia-made LED emitters.
Each dust-penetrating, non-contact sensor sends pulses in a 70-degree beam angle, taking multiple measurements from the material surface and continually mapping the material surface to detect changes in level, account for uneven surface topography, and calculate a highly accurate volume estimate for the contents of the silo.
This collection of articles describes both processes as they are planned and engineered with topics such as a meta-heuristic for subset selection problems, beam angle optimization, fast exponentiation, dynamically reconfigurable sensor electronics and diffusion controlled cellular automaton performing mesh partitioning.
