The 1470 Series’ quadrant-specific distributions also allow for power-to-light efficiency since there’s no need to block light from areas where it’s not wanted or required. This feature also reduces the customer’s ongoing costs, as they’re only paying for the light being delivered, not for excess light they don’t need.
The bollard bases are designed with radial slots to position the posts relative to their light output with up to 30 degrees of rotation available along the fixture’s centerline. A patent-pending vertical adjustment anchorage feature ensures the 1470 Series bollards can be mounted vertically. Even if J-bolts are not cast vertical to final grade or if the project’s final grade is not quite level, installers can make adjustments of up to ¼-inch to level the fixture.
Like the Vista 1500 Series Step Lights, the 1470 Series uses Cree XTE LEDs for illumination with hot binning at 85 C and good LM-80 depreciation values. The Cree XTE LEDs in the 1470 Series are in the 20- to 30-watt range for 360-degree output. Each 90-degree quadrant requires between 5 and 7.5 watts depending on the chosen power level. Outputs range from 1600-plus lumens for the low-power-level (360-degree) option to over 2,300 lumens for the high-power-level (360-degree) option. The 1470 Series is available in 3000K (standard), 3500K, 4000K, 4500K and 5000K color temperatures.
