Back in the incandescent lighting days, dimming (whether accidental or intentional) could sometimes be advantageous to a particular lighting design.  As LED research has progressed, the engineers have thankfully moved us from high Kelvin (bluish) LEDs with no adjustability to warmer white LEDs, to (finally!) giving us the ability to dial in the Kelvin temperature, change the beam spread and dim the light output to best suit our projects’ needs.  The flexibility is amazing!

WAC Landscape Lighting fixtures give lighting designers two to three key features to adjust:

Yellow defines what is adjustable on each fixture. 

With adjustable fixtures you can easily dial in the intensity, the beam width and select the Kelvin Temperature (color of the light) that works best for any given object being illuminated.  The fixtures adjust with a screw driver or the simple turn of a collar on the fixture body. Very easy to accomplish and requires no special equipment or programming.

The key thing to remember with adjustable LED fixtures is that you need to size your wire run load and your transformer(s) based on the highest wattage setting (whether you use it or not).  Tally the “VA” (Volt Amps) for each fixture on a wire run and the total connected to a specific transformer, and keep it less than 80% of the listed capacity. If you undersize the wire or transformer(s), and use a higher wattage setting (brighter light), you run the risk of overloading the system.  Wire and transformers can shut down, melt or burn in an overloaded condition.

So as you’re planning your lighting designs consider the flexibility of being able to adjust fixtures on the fly in the field.  No more having to swap fixtures or lamps out if you need a different output.  The best thing you can do is experiment and see what different settings look like on different objects.  And most importantly – have fun with it!  Lighting on the whole, and particularly specialty techniques like shadow lighting and silhouette lighting, really ups your game, and if a well-designed landscape is the “jewelry” on your home, then lighting is what adds the sparkle and brilliance to the jewels.
