Hello Dan,

Please allow me to offer some insight!

The effect which you are trying to achieve on the tree will determine what type of fixture you use and how many you use.

Judging from the current size of the tree, a spotlight with a medium/high level of light output (lumen count) and a wide beam spread would do well to illuminate the entire canopy of the tree. However, if this tree will grow significantly overtime, it may be wise to use (2) spotlight fixtures to up light the tree from either side and preserve the 3D effect.

As with any landscape lighting project, I would recommending using LEDs for their increased efficiency and longevity.

As for lighting pergola uprights or privacy screens, scone style lights are typical used as the light output is complementary to the features of the objects and provides functional light as well.

For some reference:

*(Traditional Up/Down sconces)*

*(Up/Down Deck Lights)*

For uplighting the other trees, it is difficult to make current recommendations on features that may grow immensely; thereby changing the lighting effect. But, some basic guidelines can still be applied:

On average-sized trees, standard spotlights (MR16 bulbs or integrated LEDs, medium level lumen count) would work well. For the smaller-sized trees/shrubs, consider using fixtures with lower levels of light output (lumen count); such as MR11 fixtures. Make use of narrow beam spreads for narrow trees/objects and wider beam spreads for trees with larger canopies or for wall washing effects. All LEDs selected should have a color temperature of 2700k (most commonly preferred in landscape lighting for its subtle but crisp nature).

The brand which you decide to use is at your own discretion; I would recommend one with reputable quality and favorable warranties. Regardless of the fixtures you chose, be sure to check that they are compatible with your existing transformer.

Hopefully this was helpful!
