Obstruction Light Uses Solar
Hughey & Phillips’ Horizon series L-810 LED-based obstruction light can be powered using a solar array. The low-intensity product is suitable for FAA L-810 steady burning lights and is available in both single and double configurations, operating with a range of 95-277 VAC and 9-48 VDC. H&P says the light lasts 15 times longer than incandescent models and uses about 96% less power.

Two-Pole Switches At 1000 VDC
ABB says its line of switches from 100 to 360 amps are the first two-pole disconnect switches in the industry to achieve a 1000 VDC rating per UL 98B. The switches, made for use in combiner boxes and at the inverter input, occupy up to 50% less space while saving energy and reducing wiring costs. Previous switches required up to six poles wired in series to break 1000 VDC.
